Well, the snow is finally leaving, and thoughts of gardening are filling my days. I love Oriental lilies, but I hate those darned red lily beetles. Last year, I must have squished hundreds. I ordered some Neem Oil. Thought I would give that a try this year. I've read that there are mixed results with this product. Have any fellow Canadians tried Neem Oil, and what were your results?

Any other suggestions for controlling this horrible pest? Other forums suggest imidacloprid, but I don't think it is available in Canada. Thanks.

RE: Lily Beetles

I've eliminated a lot of lilies because of the beetles. I'm just not willing to do that kind of maintenance on a large scale. I check for the eggs (red lines on the back of the leaves) and wash them off by running a soapy paper towel up the stalk from the base. If you can kill the eggs, you are obviously going to get fewer beetles. I have noticed that they bother some lilies more than others. Regal lilies seem to be less bothered than most - perhaps their narrow, coarse leaves are less attractive egg laying sites. But there are some broad leafed types that also don't seem to be as bothered, which surprised me (I'm not sure of variety names for those...) In my garden, the ones that seem most affected are the lilies with medium wide strap-like leaves. Pay attention to which seem most targeted and maybe you can edit your lilies down to types that seem less bothered by the beetles....

I've heard that cultivating the soil around the lily plants in early spring to expose the hibernating adults is useful, although I'd be very careful not to cause root damage. I've found that a lot of vigilance early in the season is the most effective, eliminating the eggs (which are fortunately brightly coloured and that I just scrape of with my fingernail), killing those disgusting larvae which I refuse to touch with my hands (I knock them off with a twig or something into a bowl of soapy water) and squishing the adults which are easy to catch. Last year I had almost no trouble at all. Of course it helped that I had few neighbours close by growing lilies. I moved over the winter and have ordered a fair number of lilies (OK, so I'm addicted) and it will be interesting to see how it goes. I haven't tried Neem oil yet, because although I am a very lazy gardener, I am also a very cheap one and will rarely spend money on a product if a free method works. But I would definitely try it before getting rid of my lilies. Daylilies are nice enough, but they're just not the same thing, are they?


 o
RE: Lily Beetles

Thank you for the replies. Janet, I agree, Daylilies just aren't the same thing. I have many Daylilies in my garden as well, but the Orientals, are just stunning. I can't resist them. I will try your suggestions...I've never seen the eggs...guess I don't really know what to look for. I will try the Neem oil this year, but it hasn't had rave reviews in the other forums. I'll post my results. If anyone has any other suggestions, I'd love to hear them.

The eggs are a reddish orange, and laid in rows on the undersides of the leaves. And look for the larvae especially on the lower leaves. At least they start their munching where it does the least damage to the appearance of the plant (and where they are least likely to get noticed).


 o
RE: Lily Beetles

I also had major trouble with those little beggars. I used 'Creepy Crawly' the household bug spray for all the nasty critters like earwigs, roaches, ants etc. I used it because it was all I had on hand at the time. It did work. I've heard that Seven is also effective, but haven't used it personally.

I'm usually not a chemical type of person, but I was desperate to get rid of them. These beetles are nasty and will eat through your Asiatic and Oriental lilies in record time. If you're an organic gardener, then your plan of attack will probably include neem oil and the old 'squish & drown' method.

I finally gave up last year & shovel pruned the majority of my lilies. It broke my heart! I left a few, simply because I couldn't bear to part with all of them.

No way - I refuse to part with my lilies - I spent 100s of dollars a few years ago, and never saw a beetle until last year (then I saw 100s)- there has to be a way to get rid of them! I was hoping neem would work, but apparently not? I am going to try and be very vigilant and get them in the egg stage...............shall see - life will of course get in the way of my good intentions.

RE: Lily Beetles

Oh, no...I hope I don't get any lily beetles, I haven't so far, but it sounds like we all will encounter them 'cause there-a-comming!!!!!

Most of my lillies are in large containers on the patio, I was thinking of putting them in the ground...changed my mind on that now tho. I'll be able to watch over them more easily this way.

I only hope this infestation will "run its' course" and be gone in the future. I hope this compares the ladybugs....they were out in swarms three years ago here in London (they were so dense that entire sides of buildings were covered with them...and they exhibited the non-typical behaviour of biting too!). Last year their numbers had dropped down to near normal, but they were a concern. Not as destructive as these @#@#*&^% lilly beatles. Oh well, I'm prepared to get some neem and a bowl of soap. I love my lillies, what lovley scent!!!!

RE: Lily Beetles

I don't see any reason why neem oil won't work - I've been using it this winter to control my usual pests and it has worked FAR better than I'd hoped. The only thing is that to work as an antifeedant it has to stay on the leaves, and you might have to spray after it rains (it also kills on contact and inhibits the growth of all stages, so even if it is washed off it would still be worth spraying). It would probably be a good idea to spray on a weekly basis anyway - just to keep them from coming back!

So far I've been lucky, and I haven't seen any nasty beetles. I know they're in my area, but maybe because I only have a few they haven't bothered me - I hope...

RE: Lily Beetles

Honestly, if you keep physically removing the eggs, larvae and adults you will see success. I was really vigilant one year (you might say obsessed) and my problem has pretty much disappeared. They are so easy to remove that the only investment is your time.

Now don't get me started about Iris borers! AAARGH.

RE: Lily Beetles

Hey wait a minute! Are you people saying that the red lily beetle is still a menace by the time August comes around???

I though these beetles came only in the early season with Asiatics, and cease shortly therafter. I just bought an oriental lily for a friend who gets the red lily beetle something bad on her Asiatics. I bought her an oriental lily in hopes that the beetle's lifespan is over by the time it blooms in August. Please don't say it isn't so :(

Is the red lily beetle still around mid-late August?
Will they attack oriental lilies?

If you don't get rid of them in spring, yes, they're around all season. The adults hibernate in the soil near the lilies. If you get rid of them well in spring, you'll only get the occasional "fly-in" from somewhere else, and how bad that will be depends on how many others there are in the neighbourhood. I have heard though, that they like Asiatics better than Orientals. Don't know if it's true or not.

As you can see by my other post ("Just killed 16" or something like that), I've been killing them for a week - this past weekend the count topped 100 - today I got 2 more. On the weekend most of the ones I killed were in pairs making MORE lily beetles!!! I don't clean off my beds until spring, leaving everything for the birds, so they were emerging from around the lilies and hiding under the leaves and stuff - tok me a long time to carefully clean off the beds. They were far more active this warm weekend and kept trying to fly away. My large fritillaries are up a considerable amount and I am going to inspect them carefully later today. I have been finding them on my emerging irises as well. As the other lilies emerge I will check and spray with neem and dishsoap - I really hope all of this effort works! I love my lilies.


 o
RE: Lily Beetles

When I lived in Montreal I kept two bricks by the bed with lilies because I couldn't bear to touch these disgusting things. The bricks were very effective, I killed about 100 and the following year there were many fewer.

 o
RE: Lily Beetles

Watch out in early spring for the Lily Beetles on your Fritillaria. When the lilies are still small and the crown imperials are going strong, the lily beetles show interest.

Cygon, a systemic pesticide works well for me. 2-4 applications during the summer, I just spray it on the leaves and it works wonders. It's strong stuff and even though I'm fairly neutral on the pesticide topic, I really want to minimize it's use. It gets applied to the one small clump of tiger lily that I've chosen to keep.


 o
RE: Lily Beetles

I noticed most of the posters on this subject are from Ontario / Eastern Canada. Does anybody know if this is a problem on the West coast? I will be checking my lilies carefully now but I have never noticed a problem with this particular pest.

Cheers,

 o
RE: Lily Beetles

I believe the lily beetle was first introduced into North America in Montreal more than fifty years ago. There have been several other new sources of infestation, but the fact that it has had lots of time to establish in this area means that it is much more common in Ontario and Quebec.

But... Things being the way they are - bulbs being shipped all over North America by individuals and companies... It's only a matter of time before the beetles get established in any area that they'll tolerate. So you guys on the west coast might not have them - yet, but if you ever see a pretty red beetle - *KILL IT*.

Don't know about Sevin I really don't like to use chemicals if I can help it - but try the manufacturer's website. Squishing really seems to be working - did find a dozen or so more on my fritillaries that are budding, but they are all dead now! I just hope that this does keep the population down for the rest of the season.


 o
RE: Lily Beetles

After squishing a handful of these guys earlier this Spring, I did 2 things:
1. I sprinkled Sevin dust over all my Oriental Lillies (one application only)
2. I put down about 4 inches of mulch

I haven't seen one red devil since. The lillies all look healthy, with some damage from the early bugs. I'm keeping a close watch on them, but so far, so good.


 o
RE: Lily Beetles

I concur! You must squish the guys early in the season, unrelentlessly! Thereafter, they really slow down and pretty well peter out the rest of the season.

I used this approach last year and was very successful. This year I have had very few and my lillies are looking there best ever.


 o
RE: Lily Beetles

I agree with squishing. Once you are rid of the adults you should be o.k. As long as they haven't laid too many eggs.
They have a thirty day cycle. You must remain vigilant over the summer to make sure they are kept clean.


 o
RE: Lily Beetles

My squishing has been successful - I occasionally find one or two, and did kill 2 larvae on some small fritillarias that had finished blooming and were hidden by other plants. I have found a few eggs and dispensed with them - nothing compared to the 100s of beetles and lacy-leaved lilies of last year - I continue to be vigilant - good excuse to spend more time walkign around the garden! I have lovely healthy lilies, just starting to bud..............now, the green worms on the columbine are another story, but my spray of Murphy's oil soap in water seemed to take care of them.

RE: Lily Beetles

MG. Haven't reached the west coast YET. Please please, soak all your new bulbs in a mixture of javex & water for minimum 30 mins and then rinse well before planting. This will stop you unknowingly introducing them to west coast. Ditto for iris. Submerge any new iris from east coast for minimum 30 mins to make sure you don't put aan irisborer in your garden by mistake. Borers are not yet on west coast either - yet.

What I did when living in Ontario. I put white paper down and shook liliy beetles onto it. Still hadto check under every leaf for eggs though.

 o
RE: Lily Beetles

Well I had to break down and finally spray. I had controlled the adult population very well but...... They had laid many eggs which hatched into disgusting lily eating monsters. I only sprayed the lily stems and avoided any other flowering plants. THey seem to lay their eggs on the lower leaves so they are hard to find. I checked a day after and they were nicely dead. The good thing is the sprays work little on the adults but kill their babies. I think I have prevented the next generation from moving on . The question is did I get them all . We shall see.

These are the most disgusting and devious creatures there are. They actually cover their babies in poop so that even birds won't touch them. Works, doesn't it!?

They seem to prefer my oriental Casablanca and Stargazer lilies the best, although they enjoy the asiatics and Orenpets as well. They seem to have less fun on the trumpets for me as well and I agree that the leaves are too thin for them and they are a challenge.

RE: Lily Beetles

I have been away for two weeks, and in that time ALL of my lilies have been decimated by these bugs! boo hoo. I have not been able to find cygon here in Ont. should i bother now, or just cut them down (what's left) and remulch? Ant suggestions are greatly appreciated. Honestly, they look like they've come out of a nuclear winter, and those bugs are everywhere.


 o
RE: Lily Beetles

They're pretty fast little buggers arean't they! I only found my first ones ever a couple of days ago, but because they're well established in my area I've been checking every day or two for years. Four larvae and one adult took some noticable chomps out of my lilies in just a couple of days.

Cygon isn't available in Canada unless you're a commercial grower of some kind, and then you need permits - it was pulled from store shelves several years ago because it's moderately toxic.

Neem oil should work (some neem oil products are less effective because they're too dilute - it's not an approved pesticide yet and therefore there are no minimum standards of potency)- it probably won't have much effect on the adults, other than to make the leaves unpalatable and force them to go to an untreated plant, but it should interfere with the growth and developement of the larvae. The larvae won't be able to turn into an adult and lay any more eggs. Some plants can take up neem oil through the roots and it then becomes a systemic and can kill that way - I have no idea if lilies have this ability, but it wouldn't hurt to drench the soil around the plants just in case.

I would not recommend mulching - the larvae will drop to the ground when ready to pupate and the mulch will just give them plenty of places to hide in. You might actually want to scrape off the top inch or two of soil around the plant and replace it with fresh soil.

Many people have recommended squishing, and I agree - you can wear disposable latex gloves if the ick factor is too high, or you can wipe the larvae off with a damp cloth. The adults can be knocked off into a dish of soapy water or grabbed with a soapy cloth and sent for a swim - they can fly away so you have to be quick!

RE: Lily Beetles

When I started this thread back in the Spring, I was hoping someone had a miracle potion to keep these critters at bay. With no miracle cure, I did the daily pick and squish routine. Every 7-10 days, I found a few more adults, then eventually no sign of them.

My picking and squishing efforts were also well worth the effort. The late lilies are blooming now and not a sign of beetles. I did find a few on the asiatics, but made short work of them. I an sure they are still around, so I will do the same next year - dig around the lilies as soon as they start to emerge and get them while they are sluggish! Now if someone could tell me how to deal with the grasshoppers that are eating everything (lily blooms included), I would be grateful.

RE: Lily Beetles

I live in Nova Scotia, environmental-hypocrite capital of Canada. It's okay to kill plants and animals and their habitats if you're a developer but if you're a peon gardener there is nothing here to control pests, especially this *!#@ beetle. Does anybody know where I can buy in Canada "Bayer Provado Ultimate Bug Killer", and/or "Merit"? Their "magic" ingredient is Imidacloprid. There's another product called "Bioneem", made from oil from the Neem tree that's supposed to be effective also, sometimes appearing under the labels of "Turplcx", "Azatin EC", "Margosan-O", and/or "Align". I'd liie to buy and try that as well. Help!!!! My liliies are slowly being devoured. I check them several times per day and can't keep up with freeing them from these pests.

RE: Lily Beetles

I live on the Quebec-Vermont border and these little bugs are driving me CRAZY!!! I've been having a squish fest for some time now with the adults but only noticed the larvae on the back of the leaves today. EWWWW! They are disgusting little things. I bought some Safer's insecticidal soap in hopes of killing the larvae at least. The adults are easily squished so I'm not worried about them. I just hope I can get rid of the next generation because thy've really done a number on the bottom leaves so far.


 o
RE: Lily Beetles

Check out your local hydroponic gardening suppliers - they'll have Neem Oil on the shelf (one good brand name is Einstein Neem Oil) in concentrated form that needs water & alittle dishsoap to allow the oil to mix with water.

I put on a pair of dollar store wool gloves overtop of a pair of dishwashing gloves and soaked the gloves in the neem mix, I coated the underside of every plant leaf with this solution by simply cupping the gloves together with the stem in the middle of my cupped gloved hands, and this gets each underside leaf wet with the solution as well as dislodging any eggs, starting from the bottom/base and moving up the plant in a cupping-like fashion.

I dip the gloves into more solution for each plant, coated the leaves and dripped the excess on the ground near the base of each lily and move on to the next plant.

My lilies were dessimated last year but this year, I've killed about 40 adults and with the wet-glove treatment, manage to elimating the underside of the leaves of eggs. I have maybe 6 leaves with slight damage from the initial adults that I've subsequently squashed and I repeat the neem oil glove trick every two weeks to keep the underside of the leaves 'egg free'.

I may slow down and only do this treatment monthly now as there hasn't been a slug or adult in sight since I started doing this in early May..I have approximately 60 lilies stalks out there so it takes about 1/2 hour to do this 'stem in wet gloved hand' trick. But if it means I'm reducing the overall population and keeping the eggs from developing into slugs - I'm happy and so are my lilies.


 o
RE: Lily Beetles

That's a great idea sydseeds! I've done something like that with my bare hands for my cardamom (trying to control thrips), but I find neem oil is so stinky, and the smell lingers on my hands for a day or two.

So far no lily beetles in my yard. I only saw one adult last year, and just a few larvae and eggs. I'm checking daily, and keeping my fingers crossed. I've got about 30 stalks so I'm not a major target, but still (would have had over 40, but the squirrels had something to say about that)...

1% Rotenone Powder - Is This The Answer?

Hello fellow Canadian gardeners! This is the first year I have dealt with red lily beetles - ugh! Although my primary interest is daylilies, last year I purchased a *lot* of oriental, LA and asiatics to tuck into my beds as they are just so breathtakingly beautiful and complimentary to the daylilies. After reading this thread in the early Spring, I knew to keep an eye out for beetles and sure enough, I saw them a couple of weeks ago. I have hunted and squished and spent entirely too much time trying to rid our gardens of these pests. Today I found the bottom half of leaves of two beautiful orientals that were almost destroyed by about 20 larvae and I declared battle on the bugs. According to a University of Guelph page, rotenone is a possible insecticide. I sprinkled Green Earth 1% rotenone powder that I happened to have on hand on upper and lower sides of the leaves and within an hour the larvae dried up and fell off.

This is my first try, but the results seem terrific and the cure is one I have not seen any references to... rotenone is an organic pesticide, reasonably non-toxic (unless you are a fish), fairly inexpensive and easy to use. Wondering if anyone else has tried it and what your results were.

Cheers, Marquisa


 o
RE: Lily Beetles

Good for you for squishing - that's the best method of control if you have few enough lilies. I'm not sure how you feel about pesticides, but rotenone is not as safe as you think it is (see here). It can be quite dangerous if inhaled, it is a proven teratogen (causes birth defects) in rats, and it causes parkinson-like symptoms in rats, dogs and monkeys. That doesn't mean it will be as dangerous to humans, but would you take the chance if you were pregnant or had children around? It breaks down very quickly in the environment, so it's long term effects aren't severe, but because it breaks down so quickly, it isn't around to control the pests you want to eradicate. You have to use it repeatedly to achive control.

I know I can be a bit of a soapbox preacher when it comes to pesticide use, but I believe that there aren't adequate warnings on the labels to educate us to the possible dangers of these things. If you think about it - is killing lily bugs worth that possible risk to your or your children's health?

You can buy neem oil from Richter's. That is a safe (but smelly!) way of controlling many pests, including lily beetles. Or you might have to do as claubill and many others have done - throw in the towel :-(. Populations have been exploding over the last few years, and there's not much to be done about it.

RE: Lily Beetles

Bonniepunch - thank you for the education on Rotenone. I learned a lot from your link and found this link coming out of the U of Guelph where they analysis the connection between Rotenone and Parkinsons disease:
http://www.gene.ch/gentech/2000/Nov/msg00029.html (this study openly states that when compared to most botanicals, rotenone is the most toxic to humans and other mammals - they go into great detail about the scary effects in the section entitled "Added Notes on General Toxicity" that goes well beyond Parkinsons and into Acute toxicity, Chronic toxicity, Reproductive effects, Carcinogenic effects, Organ toxicity, etc.

Bonniepunch - you can jump on the soapbox anytime - I really appreciated being able to learn alot about this relatively unknown botanical which is not as safe as the makers may tout it to be. Cheers

RE: Lily Beetles

Wow am I super glad I came across this thread.

I saw a red beatle on one of my Oriental Lily and I didn't think much of it. It was nice looking and I thought it was there to help control aphids and other pests but after reading this thread, it appears it is the pest.

One day, I notice there are holes in leaves of my lily and since I didn't see any other pests around the lily but the red beatle, I knock if off the lily instead of squishing it, thinking nothing more of it. I didn't know it was a beatle that specifically attack Lily, until now.

Guess i'll keep more of a vigilant eye on my lilies from now on. I hope it was a male and not a female that was carrying eggs.

Thanks for the post.

RE: Lilly Beetles

Hello. I am an avid gardener who enters the garden competitions. I have over two hundred Asian Lillys in my front garden. In the past years I have fought Lilly Beatles with a vengance. Watching the plants and killing each bug one at a time and still I would lose the battle. But not this year. I mix 15 ml of Neem Oil and 15 ml of Insecticidal Soap in a one litre spray bottle of warm water. Then after spraying all of my plants and the neighbours as well. I kept looking for the elusive little critters and if I saw even one I sprayed again. Now I have beautiful growth and no holes in the leaves. I haven't lost any of my plants. I now use the Neem Oil mixture on my whole garden to take care of a host of unwanted insects. It can also be used on your indoor plants as well. It is non toxic. I purchase the product at the Co Op. And have found that by mixing it stronger than the container states. I have had great success in overcoming the problem.

RE: Lily Beetles

This topic, surely was interesting to read.
I as well have had trouble with the Red Lily bug. I worked hard on the problem for three years, and each year thought I had beat it but by mid sumjer they where back at it and winning.
I believe the problem was that you watch for them early in summer and squish and spray etc. but with a large number of garden beds, there is so much to do, that you don't have time, perhaps to be as dilligent with squishing and watching them as your attention is on other things.

Fortunately, we moved. Two years ago and not a sign of a lily bug until the other day. When I found four of them on one plant. I cut the plant right down, it had fortunately finished blooming, just. Put it into the can in back I have for burning, and set it and some newspaper etc. on fire
Have not seen anymore. What a dreadful sight it was.

I will keep in mind what you have found successful, Gary.
It was fun, a good laugh and interesting, reading all the comments.

RE: Lily Beetles

So you have those beetles too. I tried the neem and it helps, but then I used some cigarette tobacco, leftovers in front of stores in those big ashtrays. Touch them with rubber gloves.
soak this in warm water sovernight and mix with the neem solution, seems to work fine.
need a source to buy soldier bug (podisus0 and lacewings,
ANYONE CAN HELP ME?

RE: Lily Beetles

I really don't like using chemicals in the garden, but I have resorted to using Sevin powder on the red lily beetle. It really seemed to work, along with diligent picking and squishing of the bugs.

RE: Lily Beetles

Hi, Does anyone have a photo of what these beetles look like? And are they really out in April in Zone 5? I have had asiatics for many years and a few other kinds for about 7 and I have never noticed any beetles on them. I live out in the country though and don't have close neighbors. I have purchased several new Lilies this year and want to be prepared. Does anyone also know where you can get neem oil. I saw it at the Stratford garden show and maybe should have bought some considering all of the pesticides that we aren't going to be able to get in Ontario after this month.
Also does anyone in Ontario know what this "Preen"(I hope that is the name) is that appears on many gardening forums here? It sounds like a pre-emergence pesticide that you spread on the ground. Is there anything in Ontario that is like that for gardens?
Thanks

RE: Lily Beetles

Hi Swontgirl:

Wow, this is the thread that will not die (started in 2005) much like lily beetles.

Neem oil is a plant extract. It is NOT a pesticide. The product was originally used for making your houseplant leaves nice and shiny (sort of like an Armour All for plants). It can help with some bug problems as it can suffocate small bugs and insect eggs. But again it is NOT a pesticide and after many years of experimentation I can tell tell you it NOT a great option for bug control. (Big sigh) I wish it was. I have yet to see a single organic product that actually works (even bigger sigh) decently to kill bugs. I am sure several will challenge me on this and I welcome them to come to my gardens and prove the worth of whatever method / product they are using. No flaming though as I don't use chemical pesticides. I started my green / environmental phase back in the 60's when I was in hippie movement and so had a head start on the vast majority of people here in America. Just stating the 'organic' method of pesticide control has a long way to go before it lives up to the lofty claims people already make.

Cheers,
MG

Beetles:
lilies did not even finish coming up and they are half eaten already by the red bugs. I pick and squash them by hand. Haven't tried Sevin yet - which as of today is forbidden - I went to a nursery store yesterday and loaded up on Sevin for days and years to come - just in case vinegar and soap is no go.
Neem oil - I love it and use it although I refuse to pay for ready made mixtures for mega bucks. Every Indian/Caribbean store carries neem oil for couple bucks. It's good for a gallon spray bottle or more. Just remember to add some basic dish washing liquid to it to hold it together and voila - mites are gone and leaves shine. It works exceptionally well on mites on brugmansias.

RE: Lily Beetles

The little red lily beatles showed up in my garden last spring, I had never seen nor heard of them before. They completely destroyed my lilies last summer. This year I have been doing some research on them and have found that if you pick them off and squish them and then aply a mixture of neem oil , dish detergent in warm water, shaken well that should keep them off ,so far this seems to be working I have not seen a beatle in days. The Neem oil can be found in most Indian food grocery stores.

The fact that it is a plant extract has nothing to do with it being a pesticide.

If you use it to spray for bugs - it is a pesticide. This is true by simple definition, but also by the official Ontario definition of a pesticide.


 o
RE: Lily Beetles

Sorry to be contraversial, but the derivation of the word pesticide means "to kill". If you spray some product to kill a "pest" and it doesn't kill it, then it cannot be a "pesticde" (at least not for that particular pest).

RE: Lily Beetles

Waverley, NS here (just outside of Halifax)... I became obsessed with squishing last summer when my lily garden came under siege and was almost decimated. It is now May 21st, 2009 and the lilies are coming up again. So far, no sign of the little red buggers. Canadian Tire sells a product called Green Earth Neem Foliar Leaf Spray, product #59-3838-2. I'm going to pick up a bottle, just in case, and may make an offensive strike this weekend, just in case.

RE: Lily Beetles

Hmm. ..
In my garden I found 2 of those red beetles. I squished 'em good. I have potted lilies that are about 80ft from the garden lilies. I haven't seen the beetles there yet. Every couple of days I go hunting for the little buggers.
THanks for the tip Jetjock. I will have to go searching for that spray tonight. Only wish it would work on deer as well! ;>

RE: Lily Beetles

Don't get rid of your lillies. I have come up with a good solution to get rid of the beetles, that won't cost the earth.
I went out last Sat. to buy the spray. I noticed on the 1 that 1 ingredient was cooking oil, on the other was soap.
I went to the grocery store and bought veg. cooking oil and
I use Sunlight dish soap. Erwigs do not like Sunlight soap, so I thought why not mix up some cooking oil with my sunlight and spray my plants. It works. I use.
1 cup cooking oil, 1/2 cup sunlight dish soap put in 1 liter
spray bottle fill with water. Shake well and spray all those bugs on your lillies. Within 2 sec. the big beetles were dead. it will also kill the lauva I'm keeping an eye on the eggs to see if it kills them 2. Also I have been spraying the ground around all my lily plants.
Try this and see what you think? It works for me.
Good luck with your lillies. I just love mine and refuse to get rid of them.


 o
RE: Lily Beetles

I grab the adults and drown them in a little container of soap and water. for the larva, I spray them off with a squirt bottle of soap and water.

I have been using my method since Sat. Saw a couple
on different plants yesterday. Sprayed them and they died in 2 seconds flat. Today I checked my lillies this morning before work and didn't see any beetle's. Will check again when I get home. Here's hoping that I got rid of my infestion.

Hi Everyone

I too have a have beetle problem I guess I am one of lucky ones because I have just noticed them the other day. I have never had a problem with them although I have only had my garden for the last 5-6 years and this thread was started back in 2005.

I am in Mississauga, Ontario not sure if this a problem everywhere or just pockets of these nasty little pests. I too am going to try the recipe up above and see if that works.

Won't do much for my lilies this year, they have been chewed right up but maybe next year and I will be more vigilant about keeping an eye out for these little suckers right from the get go! :)


 o
RE: Lily Beetles

I have been fighting the lily beetle battle as well. Picking, squishing, and some insecticidal soap. I as well do not like using chemicals in the garden, I'm so concerned about the bees :(. I'm going to also try the recipe above. Would the soap hurt beez and butterflies I wonder? I haven't seen as many adults this year, but I was relentless when seaking out and distroying the tiny eggs. Slightly off topic, but another lily destroyer I have are SLUGS! They like to hide out in the day lilies and then suck the life out of the asiatic foliage. Someone suggested shallow containers of beer, but it's not that effective. Do egg shells really work? Any suggestions?

RE: Lily Beetles

Holy Freaking WOW! So I'm a Brownthumbed Photographer and I am trying DESPERATELY to garden (as my inlaws are all pros... *sigh*) and decided to get adventurous this year and plant what I think are asiatics, and some cala lillies...

Well I just had my first cala come up and darned is it gorgeous! HOWEVER right beside it is my asiatic and I noticed this BEAUTIFUL red bug on it only 3 days ago... well didn't I notice the darned thing again but on closer inspection I now have lacy leaves to match. I'm absolutely devastated - but BLISSFUL that I found this thread (As old as it may be)

I don't know if anyone still checks this out but I'm going to go get some neem oil tomorrow with the munchkin and then spray the HECK out of my entire garden.

It just boggles my mind though because I have Tiger Lilies out the whazoo in the very same garden and have never seen this blighters before.

Cross your fingers for me!! I only have the one stalk in this area of the garden and really don't want to lose it!

Please don't do that. By spraying everything, you will kill off a lot of beneficial insects as well. If you do that, then there is nothing at all to stand between the plant eaters and your plants. In the long run, this will cause more problems with pests than you have now. Any insecticide use must be done responsibly. It doesn't matter if you're using DDT or dish soap - use only what you need, where you need it.

Do buy the neem oil, and do spray your asiatic lilies, but that's all you need to do.

Also, your Callas should be safe. While commonly called 'calla lilies', they are not lilies at all and the lily beetles will not eat them.

We put bird houses up in the garden. We also have a large garden that we can till. Tilling the soil seems to help and the birds are doing there share by eating the eggs and any beetles I brush off. With all the rain this year, I haven't seen to many, only one I fed to the birds.

RE: Lily Beetles

Hello from Digby Nova Scotia May 3, 2011, well I just killed 13 of the bad red bettle today. I actually didn't know what they were but quickly went back out to the garden when I did, killed all the adults I found and actually removed the leaved containing the eggs, scraped around the first 1/2" of soil. I will be checking them several times a day as I have asiatics and love them. This is the first time I have seen these beetles here. Oh and they have also been eating my glads as they emerge up about 6" from the ground, the fresh leaves.


 o
RE: Lily Beetles

Everyone wants to "squish" the red devil. I had my first infestation here in western Massachusetts in 2009 and battled the sucker for 2 years with hand picking and squishing adults and larvae. I finally realized that squishing may be sending phernomes out to other adults. Now, as a trial in 2011, I capture the adults and put them in soapy water. If anyone has had this experience before, please let me know as I want to know if this method works or I am wasting my time by
not squishing them.


 o
RE: Lily Beetles

I got these darn things last year and they devestated my lilies -- I have a several different kinds. I have been squishing them for the last week or so but there are lots of them. Read this thread and hit them with a rose and flower insecticidal soap from Safer. Some are dead but you have to get the soap right on them. Just bought a product with diocetimous earth (ok I know that is spelt wrong). And I got some Neem spray. I also mixed up a large yogurt container with dish soap, Mr Clean, Hydrogen Peroxide and rubbing alcohol. Picked them off and dumped them into that mixture and they were dead in under a minute but I don't want to spray that mixture on my plants. I also picked them off and hit them with Windex -- dead in under a minute -- because it has ammonia in it.

Am going to try the recipe above next time at the store to pick up ingredients and try spraying plants with it--I don't really want to spray them with Windex :-)

RE: Lily Beetles

Hey there, WOW this post is great!!! Also same question as last posted above. I found two cute beetles on one of my black beauty heirloom lilies which are 5 1/2 feet tall not bloomed yet and only 2 years old... I thought it was funny as they were going at in, in 2 days my lilies had holes in them!. I went through leaf by leaf removed the eggs, removed the larvae which I thought was dirt, removed all my leaves which were closet to the ground then used the vegetable oil/sunlight/water mix, sprayed my lilies leaf by leaf top to bottom 3 times over lol. Will this work? do mixtures like these damage the plants. I will do anything to get these beetles away. I have only seen 3 in total, 3 leaves with eggs, and 13 larvae, I also cleaned up the soil around the lilies and found nothing murking beneath, I am wondering instead of going to my nursery I went to canadian tire had a sale on lilies and some of my smaller lilies did not come back up this year, maybe they were infested.

Any help that has worked? will the vegetable oil/water/soap mis work? and will that mixture damage my plants?


 o
RE: Lily Beetles

I have to disagree with many, many comments above. So many of you are saying that if you are disciplined and get a good head start squashing the beetles, you will have less later in the season.

When I first saw these bugs in action at a neighbour's garden, I looked them up on the Montreal Botanical Garden's website. There, they say that in my zone 5 garden, there can be three swarms within one season, and there can even be more if we have an unusually long, warm summer.

Not long after, I have discovered these sons of #?&*?&*?% on my lilies, in midsummer. I went to work squashing them as best I could, as the Botanical Garden's only recommendation is to do just that. They say themselves that although several chemical and organic methods are taunted as being effective, nothing comes even a little close to the good old squashing method.

Sadly, I did not know at that time that these bugs also attack fritillaria and I planted some the very same year. Things get complicated also by the fact that I like the cottage garden look and so always plant plants close to each other and mixed together, so it is very hard to get inbetween them to do a good clean-up. I know the method whereby one shakes the plant onto a sheet of paper or cloth on the ground is out of the question for me!

This is my second year battling the beetle. The beetles that overwinter start by munching on my tulips, which usually come up about ten days before the fritillaria. Yes, I said THEY ARE WILLING TO STOOP AS LOW AS MUNCHING ON TULIPS! As soon as the fritillaria shoots are up, they attack them. Then, it is on to the lilies, all the while they still keep close to tulips when disturbed.

I don't think it is worthwhile to dig around in the soil. It is much harder to katch'em and kill'em that way. I think it is best to wait until they grow up, then they are really easy to spot and usually remain high enough off the soil that you can dump them into a shooter glass of soapy water like I do without even touching them. I am very happy when I catch them "socializing" in pairs. They seem to be on drugs then and totally unaware of their surroundings. In any case, even though they can fly all right, they very seldom do. So, dumping them into a shooter of soapy water is probably the easiest, least time consuming and least potentially root-damaging method.

I am very vigilant. My fritillaria, lilies and tulips are all at the front entrance, where I go for cigarette breaks. I check the plants almost every time I go for a cigarette and dump them into my trusty shooter glass every time. I never see more than a couple at a time, probably because I am so anal about getting them all. Still, they keep coming and I have to keep picking them off plants right up until it is just too damn cold for them to be out and about, which in my case is October.

Stargazer lilies seem to be their favorite snack here. Although I am ruthless about picking the beetles, Stargazer leaves always get the unsightly swiss scheese look by the end of the season.

I think I am going to buy one of those neat little bug vacuums. Nothing better than to be able to just "shoot" them. The vacuum has a small nozzle you can precisely target them with and it has a reservoir that gives the beetles an electric shock when they land inside. I also get cucumber beetles in my veggies patch pretty bad each year, and these fly away before you can touch them, unlike the lily beetles, so the little vacuum would provide double duty here.

RE: Lily Beetles

I HAD a gorgeous garden with Asiatic lilies. Then those voracious red beetles appeared in my garden in the late 1970's in Ottawa (zone 5) and decimated my entire stock within a week. They were relatively unknown at the time. It was babysitting money I used to build up that garden which really broke my heart. Rather than replace them I pulled them all out and started planting other garden plants. Even doing that those little red devil's plagued my garden for years. I no longer grow ornamental lilies of that type anywhere because I lost a lot of hard earned money to them. Daylilies I grow and I have wild tiger lilies on our land which I enjoy but don't care to single out just in case. I leave them in situ.

Those bugs leave one ugly mess with their poop as well. Really disgusting to say the least.

RE: Lily Beetles

Wow, I have looked a bit but will have to be more vigilant now. If this crazy weather ever settles down and warms up they will be coming out. I found my first few last fall when I was digging out some lilies I had planted for cutting for my son's wedding. They crawled out of the soil and I got a couple but missed a couple too. I was so shocked to see them as I had never had any before. This garden was a ways from the main gardens I have lilies in but it means they are closeby. I bought some diatomaceous earth at a garden show this winter to be prepared and will have to try it.

The lily beetle is back with all it's fury in Calgary. They attacked my lilies last year (all types). I discovered them just today. I'm tempted to rip out all my lilies, but like all other people who have posted, they are so pretty and so much money has been invested.

They survived the Calgary winter. I suspect they'd survive across the entire Canadian winter, not just here.

Thanks for the great info on this thread. I'm a little worried that the mild winter we've had is going to lead to some nasty infestations by mid summer so I'm trying to be vigilant. I'm already battling a ridiculous number of rose aphids and it's not even June! I'll try the neem oil/soap remedy and report back. Now I know who devoured my beloved fritillaria meleagris in the spring. Little jerks.

 o
RE: Lily Beetles

Thanks - Great link.
It answers some of my questions about the life cycle etc. I have been finding some adult beetles over the last 10 days or so. I am just squishing them. My mother-in-law seems to have more than me. I have found a few lines of eggs and squished them too. So far there isn't much damage to my lilies but then some of them are so thick any holes wouldn't be readily visible unless you were close up.
Does anyone know if there's a particular time of day the beetles prefer to be out? Or do they like sun and dislike cold etc? Do they go back to the ground at night or com e out? Anyone with more experience than me figured it out?
My husband has found more here on an old patch of tiger lilies than I have found on my other species and hybrids. As far as I am concerned they can keep eating them although we have been squishing those too! I found one larva(I think it was by the descriptions I have read) and squished it too.
The adult numbers have definitely tapered off-I found none today so hopefully that is it, but probably not!


 o
RE: Lily Beetles

I cannot believe this thread has been going for so long and I have never seen it or posted my experience.

I love lilies and have lots of Asiatics and had been bothered by the beetles until I met a lady several years ago at a flower show put on by the Horticulture students attending a college here. I used to have horrible infestations with eggs under all the leaves and some of the stems eaten bare. She gave me these directions and they work: in the spring, when the shoots of the lilies are just about to burst forth, spray them and the earth around them (that's where the eggs over winter) with a 10% solution of household ammonia. This will not hurt the plant, but it kills off most of the eggs. You may get a few of the beetles but you just catch them and quish them (I love doing this). There are many things that SEEM to kill them but the fact is, they have no predators here in Canada, and pesticides may seem to kill them but that's not the case. They usually die off after laying their eggs. My personal method is to spray the earth around the plants in the fall and in the spring. I also am very vigilant and search around the bases of the plants in spring. This is the first place of attack and I hunt them down and kill them. If they do get to the point of laying lots of eggs (that black gunk) on the under side of the leaves, a gloved hand run up the stalk will remove them and I squish them by rubbing my two gloves together. I have had a few around this year, but I usually see them before they can so any damage, and I also look for the telltale sign: little jagged bites out of the leaves. It is true that they don't attack orientals, but I have seen them on other plants, and again I squish them. I have kept them under control this way.
P.S. The ammonia spray is also great for slugs. I go out on slug patrol after 9 p.m. and spray them. Doesn't hurt the foliage, not even of lettuce, but it stops them dead in their tracks.


 o
RE: Lily Beetles

I live in Toronto, Canada, and I do have some lilies, and lots of iris, but didn't really notice any of these beetles! (hope not at least), but I used to watch the famous American Gardner "Jerry Baker" and he always mentioned using stuff like antiseptic mouth wash, and yes ammonia and add small amounts to like 2 gallons of water and spray his plants with that mixture. Actually you can look his videos up online or just get the CD's at the library as I did. Good luck 2 all :) Hala


 o
RE: Lily Beetles

RE: Lily Beetles

Yes!! I have had great success with Neem Oil....you have to be vigilant and spray often but it works. Unfortunately, it is very hard to find. I bought it at Canadian Tire 2 years but last year they didn't have it. And I found my 1st bug today..... :(


 o
RE: Lily Beetles #2

I bought an asiatic lily called "Lollipop" 3 years ago from a huge nursery in Toronto and brought it home to Barrie. By doing so, I unknowingly brought home some unwanted pests! Since then I have been battling this awful beetle. I tried spraying soapy water (hate to use chemicals) but it didn't stop them.

The surest way to get rid of them is to squish them!

Each day, at least twice a day, I run my hand up the stalks of my lilies (I am no longer squeamish) and dislodge any larvae sticking to the undersides of the leaves. It's messy but worth it if you want to enjoy your lillies. i look at ALL undersides of leaves for the new beetles....it's alarming to see a very straight line of new beetles, sometimes as many as 6 or 7, or as few as only 3. They remove easily with thumbnail as others mentioned in the first thread.

My method of removing them physically is paying off for me; have not seen one in over a week.

Granted, I only have 3 or 4 asiatics so it goes quickly for me. I feel for all you lily lovers who have lots of lilies...this is a time consuming chore, and not a pleasant one.


 o
RE: Lily Beetles

A gardening expert on the radio said that heavy insect infestations go in cycles, so it appears to me that the reign of terror of the red lily beetle is finally at an end in the Montreal area.

I have seen no more than 5 or 6 of the little buggers so far this year and my lilies have no bites marks on the leaves or unopened buds. and my first open Farolito lily is perfectly beautiful.
