While earwigs do not carry diseases that would affect humans, their presence can be unnerving. The elongated body of an earwig has a head on one end and pincers at the other for self-defense. Its appearance can be enough to frighten people, which may have caused a false legend regarding the bug's ability to burrow into human brains through the ear canal. Remove these creepy crawlers from your home with natural solutions.
Traps can help you determine how many earwigs you have and how bad the infestation is inside your home or in your yard and garden. Cut several sections of garden hose and stuff them with damp newspaper. Leave them out overnight and check them in the morning. If you find earwigs inside, simply dunk the hose section into a bucket of soapy water to kill the bugs inside. The earwigs enter the hose because they hide in dark places during the day and require moist environments for survival. Alternatively, plastic tubs half-filled with vegetable oil can trap large numbers of the bugs. Skim the dead bugs off of the top of the oil each day with a plastic spoon to continue using the trap.
Create a spray to use as a spot treatment for when you see earwigs and to routinely treat areas where earwigs have been seen. Pour 1 quart of insecticide soap into an empty reusable spray bottle with 1 tablespoon of isopropyl alcohol. Spray high-traffic areas every day to two days and spray any newly discovered point of entry as you notice bug activity. Use this spray, both indoors and out.
Both boric acid and diatomaceous earth will dry out an earwig infestation when placed in the most effective areas of your home and yard. Sprinkle either powder in cracks and crevices along interior and exterior walls where bugs may be getting in. Any dark and moist areas indoors could be hiding places for earwigs so sprinkle either of the powders in those areas as well. The bugs that run across these powdered areas will track the powder along the usual bug route until they dry out and die. Other bugs that follow the same route will also die.
Spread an even layer of diatomaceous earth around the perimeter of your home and garden to prevent entry by earwigs. Diatomaceous earth dries the bugs out and eventually kills them. Earwigs require moist environments, and the diatomaceous earth acts as a desiccant, drying the bugs to death. Replace the diatomaceous earth every spring and continue spraying the bugs with your natural homemade spray when you see them outside.
