Earwigs got their unique name from an old European myth, which told of bugs crawling into the ears of sleeping people and boring into their brains. Naturally, this is not true. However, earwigs are most active at night, and they are prolific climbers.
Earwigs are most recognizable by the two pincers at the base of their bodies. They are scavengers and feed on dead animal and plant material. Earwigs can also do damage to live vegetation and are often found in mill or grain storage houses as well as greenhouses. They are attracted to lights and can invade homes by the hundreds or thousands.
The most common infestation of earwigs occurs in homes with shake roofs. They thrive in the dark, moist wood of the shingles. Power-washing the roof thoroughly and then sealing it every two years will eliminate this problem.
Keeping a low moisture zone around your home is also a good earwig repellant. Remove all mulch and debris and put down a gravel layer up to a foot around your home.
