Earwig infestation

Posted by photopilot 5, SLC UT. (My Page) on

Just as things are starting to look good around the garden, we notice small holes in the leaves, and some plants are just a few days short of being devistated at the rate it is happening.

We went to the local farmers market and talk to the "master gardeners" they said it was probably earwigs. We went to the local garden store and the expert there said to spray carbaryl, which is the same as Sevin. We were desperate to save our garden so purchased this and brought it home. I did not like the though of spraying insectiside around our mostly organic garden especially after reading about the product. We also have cats in the garden, I read it kills bees, trout, etc. The final straw was having to wear pants, long sleeves and closed toed shoes. I decided to look for a healthier alternative to spraying.

So last night I put a few of the Oil, Molasses, Soy traps around the garden. There were some small looking earwigs piled in each one this morning.

Having read previous posts about earwigs I realize we have some issues that are beneficial to there existence in our yard. I'll describe the garden in hopes of coming up with a plan to reduce the pest damage without using chemical warfare. The garden consists of two beds 12x10 feet each. We have a number of plants that are densely packed into the garden beds (mixed greens, potatoes, onions, squash). The second bed was a mess with weeds, so we laid a bed of mulch in the form of hay just a few days ago. Because of our schedule we are only able to water the plants at night when it is cool.

So those are the conditions in the garden that are encouraging our earwig population. Now that I realize i have a problem what can I do to fight the little menaces?

The tuna can traps seemed to attract and kill them and I will try the newspaper trick. How many of these traps and how far apart should I place them? Do I need to change them each night or can i let them marinate? Any other suggestions on how to fight them, besides getting rid of the mulch, then what do I do about the weeds?

Thanks for any help.

RE: Earwig infestation

Some bad advice there since Carbaryl is not something you would wnat to use first, and suggesting that any given insect might be the cause of the problem with no further investigation is really poor judgement on the part of those "Master Gardeners", and I would tell them. Something that potent and long lasting should only be used as a very last resort, maybe just before burning the garden off.
Have you, or anyone else, see any Earwigs?
Have you considered the possibility of slugs?
Have you considered the possibility of any other insect?
IPM means properly identifying the problem once it is established that a problem actually exists and then applying the least toxic means of control possible.

RE: Earwig infestation

So we started out with a few of the soy traps and found a bunch of things in the morning, including many earwigs. There are no slugs around but the occasional snail. So we have now spread the traps around all the favorite plants (for pests). We are getting a lot of things in them each day, not just earwigs, I hope I am not decimating all my beneficial bugs. The rolled up newspaper has yet to yield any earwigs.

With the traps our eaten leaves are now at an acceptable pace. Now we are looking at beneficial nematodes to control them. Will let you know how that works.
