I hate these bugs! Come spring we're inundated with them. They love all things moist and dark, under parts of plants, under rocks and in any garden plant litter. They do not confine themselves to the out of doors. It is not uncommon on opening doors to have dozens of these creatures run from under the door and from the top of the door. I think I would have to make my house a toxic dump to get rid of the earwigs and I refuse to use poisons.

I took one of these bugs to a local nursery last summer to see if I could get it ID'd. It suddenly seemed to be everywhere in my garden. The staff person said, "Oh, that's an earwig but we've always called them "pincher bugs" because if you touch one, you get pinched." She's right!

These are nasty bugs. I see them hiding under flower pots and such during the day. Last summer I would go outside at night and see them on my daylilies, pansies, clematis, jacobs ladder, basil, tomatoes, peppers, just about everything with a flower or fruit. I would open my cupboards and there they were. Anyone know how to get rid of them? I dont have them yet this year in Iowa, they usually dont start coming out until early to mid June and then again in aug- sept. I try to do organic gardening but I would like to get rid of them. I think they overwinter in leaf piles and such that accumalate under my front porch. It is really difficult though to get under there with a rake, I have a raised porch with lattice all the way around it... anyway, they are disguisting bugs and I am not looking forward to seeing them again this year. I never had them until about 3 years ago and I have lived in this house 7 years.

To kill earwigs bury an empty tuna can, not rinsed out, so it is level with the soil, fill 3/4 full with cheap veggie oil, add a few drops of soy sauce, sit back, and watch the little buggers drown. Great for Sal bugs too. It sounds crazy but it works.

I can't stand these little buggers. They chewed almost all of my bean seedling down to nothing! They also chewed on my newly emerging nasturtiums and sunflowers. They literaly destroyed my hyacinth bean seedlings. Thanks for the tip about the tuna can, veg oil and soy sauce. I'm going to put them everywhere, thank goodness I like tuna sandwiches!

They hide in my rabbits alfalfa pellet feeders, under watering cans and everywhere else. I read that you can also roll up a newspaper and set it in your flower bed during the day (they don't like the sun) they will crawl in. Just before sunset pinch the ends of the newspaper roll to keep them in. Then take them and pour them into whatever you want to drown them in. I have not tried this yet. I think I will try the tuna can trick first.

These things give me the willies! Nasty little things. I think they are related to the roach. I have found that if you take a spray bottle and fill it with water then pour in a bit of dishwashing liquid soap it will kill them. I go out at night with a flashlight and spray everyone of the little buggers I can find with the dishwashing solution. Kills 'em on contact. The dishwashing solution is not toxic to plants either. Try it, it works.

These are harmless detritivores, and not garden pests. While their appearance clearly disturbs many people, they are beneficial in that they help build the soil. I hope people aren't using pesticides because the appearance is disturbing.

I'm not positive that this is the same variety of earwig we have here in Cleveland, OH, but I absolutely agree with the ICK factor most of you have expressed.

I'm going to try diatomaceous earth on these little buggers around my house, as I've heard that anything that crawls basically is done in by it. I know it's hard on the ants that keep invading. And I'm not big on spraying poisonous chemicals on my foundation that just end up getting washed off and end up where? I don't believe the diatomaceous earth is harmful to people or pets. Let me know if anyone else has already tried it.

I find these little guys interesting and admirable. The female is excellent mother, for an insect, caring for her eggs diligently, moistening and turning them. Earwigs can pinch, people are right about that, but they don't do horrible, deadly things and they do not crawl into ears (nor do they sew bad little boys' ears shut, as one person informed me). I have never had any damage from their clustering in damp places in my gardens or under sun-scald shields on my newly planted trees. I welcome them to my compost pile. To remove them from the house, where they occasionally appear in potted plants, I place a glass upside down over them, then slip a piece of card paper under the glass, turn the glass rightside up with the card as a lid, and carry the whole shebang outside to empty it. I use the same method on wasps, bees, and spiders that wander indoors. Laura

I have found this bug eating my elephant ear bulbs. I could not figure out why my plants were doing so poorly, so this past summer I dug the bulbs up to store for the winter, not something I normally do. When I dug them up guess who was having lunch. Some may say they do no damage, but I beg to differ.

I woke up one morning and got ready to go to work, went downstairs and poured myself a cup of coffee that I had delay brewed.. I took the first sip and thought to myself, "Wow this coffee tastes bitter!" I held the coffee in my mouth and swished it around to feel what I interpreted to be coffee grounds. So I spit in the sink and there it was, an earwig. Not a very pleasant thing to drink with your coffee in the morning. I don't mind them otherwise, but when they're in your coffee.. it's a whole different ball game. They have such a rancid taste! I brushed my teeth and gargled for at least 5 minutes. I don't think one friend of mine failed to hear about my steamy cup of java!

I have noticed something very peculiar about this horrendous creepy-crawlies...the seem to secrete some kind of black spots, like maybe their exquivalent of urine onto the baby pepper plants that they are getting ready to eat and then, with almost the worst type of forbodding, there are clearly spots where they have been gnawing on the leaves and they were on the leaves of one when I sent out the other morning! I can't grow peppers anymore for even the Dawn doesn't seem to slow them down, much. I wonder whether the vegetable oil idea would work on my balcony...hmmm. I will try it and get back to you all! Because boy do they irritate the living ____ out of me. LOL I suppose it makes sense that the plants, which contain oils, would make vegetable oil attractive to these and other insects, I will be reporting back on this, because, in spite of having a raised plant bench, they seem to be found, along with the carpenter ants--dealt with simply with diatemaceous earth--all over, including the new potting mix, even sealed up as tight as possible without buying the kind with a zipper seal. :o( Thanks for the idea!

These nasty-looking buggers seem to love the taste of my echinacea petals, both pink and white. They either chew off the ends of the petals before the bud opens, or chew holes in them after they've opened. I don't want to use any sprays on the flowers since the honeybees & buttlerflies love them.
I've heard diatomaceous earth around the base of the plant helps, we'll see.

I used to find these critters frequently but since I have my chickens out in the yard the earwigs as well as sow bugs, ants and jerusalem crickets are becoming much rarer. This is good except the chickens get annoyed when I turn over wood, etc. and no more bugs are available. I've started raising (wouldn't have believed this before I got the chickens) mealworms for the chicks to eat.

In my experience, this bug is not harmless, as another poster stated. I have found them in plants which grow from buds contained within tightly curled leaves, where the buds and young leaves were eaten or destroyed by these bugs. When disturbed, they give off a tar-like odor. I once laid a long-sleeved shirt down on a fence and, when putting it on later, was soundly pinched by one who had gotten into the sleeve. They seem similar to roaches in their liking of damp/moist/dark places and, like roaches, will eat plant material, whether it is dead or not. Best natural control I've found is to try to provide more air movement and sunlight, to remove loose bark at the base and trunk of trees, where they like to hide, and to rake away decaying leaves and other matter around plants with infestations.

We've got bunches of them in the yard this year (and an abnormal amount in the house too) but they're great for the soil so i just capture the rogues from the house and put them back outside. Do not hate or kill these creatures because they are ugly, a good many ugly things are good for the earth. And despite popular myth, they do not get in your ear or go up your nose to eat your brain.

My first experience was years ago, while determining what was destroying my Blue Salvia annuals. After I identified the culprit and eventually tossed my salvia plants, once they became unidentifiable from the destruction, the earwigs moved on to my lupines.

They dwell in dark, damp and tight locations, during the day, and eat at night. They really aren't to picky about food sources, but they do tend toward plant structures that are deeply tubular in nature.

In 2013, I overturned a couple of large flagstone, and each stone revealed a large colony of earwigs scurrying in every direction. This happened right near one of our very old silver maple trees, where I was watering new plants on a regular basis until they established themselves, and these critters ran into hiding behind pieces of curled bark that were still attached to the tree!

They tend to show up and hang out in very wet Spring conditions, or when a great deal of manual watering is necessary, say during a drought or when establishing new plants.

Typically I'm not bothered by bugs in general. Actually I can be fascinated by some bugs, but earwigs are the exception to the rule!
