Getting rid of gnats?

Posted by gamebird (My Page) on
Wed, Sep 2, 09 at 16:47

Around this time last year, our gnat population surged. It was just a few weeks after we'd all moved in and my already irritable husband went nuts about it. We took out the trash daily, cleared out all the perishables (apples, oranges, bread, etc.), moved the house plants, poured boiling water down the drains, swabbed the toilets and mopped the floors and so on. Still we had gnats. They ended when it got really cold outside. I knew the gnats weren't due to hygiene because my very fastidious mother also had them. She said it was just one of those things this time of year.

Well this time of year, we now have them again. And again my husband is revving up for the same practices as last year, which to my mind didn't do a lick of good except give him something to kvetch about and nag me about doing.

Today I put out a saucer with some honey in it thinking the gnats would land on it and get stuck. They are ignoring the honey, right next to my indoor compost container, in favor of sitting on some okra tops in same. I tried putting some tape where they'd been sitting on the counter, but they have chosen to sit elsewhere now. Or fly around erratically, which is even more annoying.

Is there anything useful I can do to get rid of these things? If it were due to food sitting out (my husband is urging me to get rid of all the tomatoes sitting out, ripening on the counter), then I'd have thought it would have happened a month or so ago when I had partly burst cantaloupes sitting around. I had a few then, but not many. Now there's so many that they're bothering me and I'm not that much of a clean-freak.

Rather than have fights about whether my food-handling practices are attracting bugs, I'd rather do something to eliminate the gnats. What can I do that really works?

Gamebird,
It's harvest time! So, I think the problem must be caused by the compost container. Even when we keep it closed, it somehow, almost magically draws gnats or fruit flies. The only thing I know to do is keep the fresh compost in a plastic bag tightly closed, then empty it frequently into another compost container with a lid just outside the kitchen door, and zoom the batch to the compost pile once or twice a day.

I will be interested in hearing other suggestions. Give your hubby a chill pill and a hug and tell him it's not like an Egyption plague.

I've been harvesting stuff since late June. I don't get why it's a problem now. And it was a problem last year even though I didn't have a compost container inside.

RE: Getting rid of gnats?

Gamebird - I too have been fighting them and yes, it's just that time of year! However, I've come cross 2 solutions that don't cost a lot of money and seem to work for me.

The first - mix in equal parts apple cider vinegar and sugar. I then put it in a jar of some kind and sit it up on my fridge. You can make several and set them around various parts of the kitchen. Gnats are drawn to any decaying food (like bananas at my house) and for some reason, they're drawn to the vinegar smell too. The sugar will make it a bit syrupy (in time) and when they land, they can't get out and drown. I try to make sure that the jar is only half full with this mixture so they have farther to fly up to get out.

Second - mix 2 T Red Wine Vinegar plus 1 t. Dawn Dish Soap. This works well in a concentrated area like a countertop. I haven't had as much luck with this as the first recipe, but it still works. Maybe add a Tablespoon of the soap to the first recipe? That also holds the gnats in the solution and they drown.

Those little buggers are just down right irritating when they're flying around your face while you're trying to do dishes. You might also try baking soda with the vinegar down your drains and/or garbage disposal.

Hope this helps!

I tried the vinegar/dish washing solution in a little jar and in a saucer. After several hours, I have 12 dead in the jar and none in the saucer. They are within 12 inches of each other, but no gnats in the saucer! Why would that be, I wonder?

Time to get out some more little jars. I'll try some vinegar/sugar/soap and see if they like that more than vinegar/dishwashing soap.

RE: Getting rid of gnats?

Thanks for the info Paula. That makes sense. I guess I lucked out not having gnats. My pests have been these tiny little ant like bugs crawling around. I might try your fix on them.
This has been a terrible year for pests. Grasshoppers especially. I've given up trying to fight them.

RE: Getting rid of gnats?

Gamebird - the recommendation I found with the red wine vinegar said to use a saucer too, but I also found that didn't work. I used a custard bowl the next time with a little bit better success, then used a jar. The jar method seems to work much better with either recipe. I think it must be the distance "up" they have to fly in order to escape. It's much easier for any living creature to move horizontal as opposed to "up and out". I can move sideways but if I have to jump .... forget it!

Barbara - you can try this recipe for your crawling ant critters but have you tried pepper? Red or black, I've had complete success with lining my window sills and even the back of cabinets with either or both kinds of pepper. There's something about it that ants just do not like. I've even mixed a bit of grits in with just for good measure. It has ALWAYS worked. Thru the years, my young adult daughters have called me from their apts. crying "Mom! I've got ants!! What do I do?" I always gave them this antidote and they were amazed it worked. The only problem is you have to re-apply every 2 or 3 days and don't open your windows on a windy day. Maybe a combination would work? Try it and let me know! And I don't think it would help with the monster grasshoppers we've got this year.

Good luck to you both. Those critters are so danged annoying!!!!! Of course, they're mild compared to cougars! LOL!

RE: Getting rid of gnats?

It isn't very pretty but I hang one of those sticky fly strips under my top cabinet next to my compost container. It works. I bought a stainless steel canister with a rubber gasket and a latch for a compost container but the gasket warped over time and the gnats still get in. If anyone has an idea for a gnat proof container let me know. In Washington the sanitation dept requires people to compost and provide both countertop containers and outdoor composters. The countertop units are about a gallon in size, seal tightly and have activated charcoal in a filter in the top to prevent odors. And there weren't gnats in my friends kitchen.

RE: Getting rid of gnats?

These aren't gnats, in my book. Gnats are those tiny flies which make a buzzing sound in ones ear and sometimes bite. I would call these flies fruit flies. Another name for them is vinegar fly. They have a three day life cycle. That is three days from egg to fly. In between the exist as a little larva. They reproduce in decaying food, as someone already mentioned. Growing up, our house was surrounded by apple trees. Fruit flies LOVE apples. So we had them BIG TIME.

Trapping sound like a very good idea. It will also help to eliminate anything possible which is ripe or spoiling, and keep your compost pail tightly covered. Be sure you never leave stuff in the pail for a full 72 hours, and you should never have fruit flies coming out of it.

RE: Getting rid of gnats?

I use a yellow sticky fly trap like Dorothy does and hang it over the sink. (It is high enough that it doesn't hit you in the head.) I haven't had many of the fruit flies, but I carry out my compost at least twice a day, so that isn't there to attract them, or it isn't there for long. I agree with George that they likely are fruit flies....and we will have problems with them a bit here and there during the harvest season. I only have actual gnats if I am overwatering seedlings, which for obvious reasons, I try to avoid doing.

Barbara, For little ants, I've had successed with the pepper Paula mentioned, or with cinnamon.

Dorothy, I have seen compost buckets like you mentioned, but don't remember where although I'm sure it was online since your typical store doesn't carry compost buckets.

The next time I come across one in a catalog, I'll post it. I'd like to get one of those myself.

I don't have one either but there are lots on line.

RE: Getting rid of gnats?

You're right, George, they are fruit flies. A few years back in a college genetics class we had to raise fruit flies and then look at them under a microscope to identify characteristics. I had forgotten just how short their life span is but knew it wasn't very long.

Soonergrandmom, thanks for the link. I'll look as I'm about ready to retire my old container.

Dawn, You must have more compostables to have to go out twice a day, but this time of the year I take out once when I feed the chickens.

RE: Getting rid of gnats?

I use one of those plastic Folgers coffee containers. It has a snap-on lid, and I keep the lid on it all the time. It tends to get full pretty quickly, and on days when I'm processing things I have to dump it several times, but normally it holds about one day's worth. After I dump it, I wash it before putting it back into use. I don't seem to be having much problem with fruit flies, at least not yet, and DH always has bananas laying out on the counter.

I remember one year I had some kind of bugs flying around and I had a little trouble figuring out why. Finally I discovered the problem. I had dehydrated some bananas and I had three one-gallon zip-lock bags of them up in the cabinet. The insects had actually eaten holes in the plastic to get at the contents and all three bags were ruined and had to be thrown out. Now when I store dehydrated produce, it's in the freezer. I'm trying out storing a bag of dehydrated apples in one of those five-gallon buckets that I bought wheat in. It has a really tight-fitting lid. If that is problem-free I can save some freezer space in the future.

There is also some kind of fruit-fly or gnat or whatever that infests houseplants. If you examine the plant carefully, you can see the little critters milling around on top of the soil, and in and around the leaves of the plant. In years past, I've killed them by setting the plant down inside a paper grocery bag, dropping a mothball into the bag and then putting another bag, upside down, over the one that's right-side up. I learned from Dawn that you shouldn't use mothballs for stuff like this and in fact have gotten rid of what I had. I keep thinking about my Grammy Britt and how she used to store things in mothballs so much that her house always had that mothball smell. She died of liver cancer when I was 15, and she was only in her early 70's.

I don't keep very many plants in the house any more so I don't have any recommendations about what to use instead of the mothball method.

I bought flying insect spray and a box of sticky paper. Between those two, the problem seems whipped. I hope it stays that way.

Dorothy,

My garden was so late this year in terms of producing that I have been doing a lot of canning, dehydrating and freezing the last couple of weeks....more of doing a whole lot at one time instead of having it more evenly spaced out over the course of the summer. Consequently, I have had a huge amount of compostables, but it is beginning to drop off as I catch up on putting food by.

Game bird, Good. I'm glad you've got a handle on it. It does seem to be a pretty common problem at this time of year.

RE: Getting rid of gnats?

The gnats are back and driving me crazy outside my back screen door. They try to come inside and get stuck in the screen. Now that the weather is nice I like to keep my doors open and can't because of the gnats coming through the screen. I clean piles of them out of the screen every morning.

Can someone help?

RE: Getting rid of gnats?

Clair,

I'm going to assume y'all have had rain and your soil is moist right now because those are the conditions that encourage gnats outdoors.

If that is the case, you're likely going to have gnats until the soil dries up or until y'all have a really hard freeze, which in your zone might be a few weeks away still.

There are some great tips for natural gnat control on the linked page.

If you don't have pets that might lap up the soapy water, place a white or other light colored plate outside the back door. Fill it with water and add a couple of drops of dish soap to the water. It will work as a gnat trap.

Good luck,

Dawn

RE: Getting rid of gnats?

I have used the lemon dish liquid in bowls and it works somewhat. The best is the sticky fly traps over the kitchen sink, though, IMHO. However, I hung one the other day and our beautiful new kitten, Cuddles, thought it was a toy. He got tangled up in it, stuck to his tummy and back leg, and he freaked out, running (or hobbling) around the house til I could catch him. His little heart was beating frantically. I finally got it off of him, and other than missing a bit of fur, he survived. I want to hang another, but am waiting a few days to do it when he is not checking me out in the kitchen (very nosy lil thing) and hopefully it won't draw his attention.

The stuff is terribly hard to remove from your hands, I can tell you. I tried soap (not a chance), fingernail polish removed (maybe a little), and then rubbing alcohol (worked the best followed by soap).

Still the traps work for anything that might be flying around indoors!
