Earwigs (Forficula auricularia) are a common sight in many gardens. They are attracted to damp locations so can be found under plants, in mulch and anywhere else damp like decaying vegetable matter. Earwings are more of a nuisance indoors. Despite their appearance earwigs aren't harmful to humans. There is the old wives' tale that earwigs get into your ears when you are sleeping and while it could be possible, this is quite unlikely. Earwigs can be found indoors under damp clothing on the floor, in basements and walking across the floor as they look for a damp area to hide. Two areas were they can get into the house is patio doors and windows at ground level.
Earwigs can be controled by removing decaying material and mulch from around the perimeter of the house and/or as sprinkling diatomatous earth around the perimeter of the house. They can be controled indoors by keeping all damp clothing and towels off the floor. Insecticidal sprays to control earwigs are available but simply picking them up with a kleenex and squishing or vacuuming them up is as effective without adding chemicals to your home.
