Neither are they dirty or vectors or carriers of any disease. They won't lay eggs or reproduce inside your house or furniture. They are simply a nuisance and that's all. Earwigs have gland openings they can exude small amounts of liquid if the insect is disturbed. This liquid is not poisonous in any way, but it is responsible for their own particular odor.
Earwigs like to hide under cloth.
So laundry, hung out to dry, will be an attractant. Shake it out before you bring things inside. People with pools are especially prone to earwigs. If you leave your towels out to dry, by the pool, say, the earwigs will certainly like that. They like cool, moist hiding places.
