I have one site that always has a lot of earwigs. It's a good location,
morning sun, afternoon shade. But the earwigs bother me.
Earwig traps can be made with a hollow tube (the tubes on the pants hangers
from the dry cleaners are ideal). Simply place the hollow tube (about 6
inches long with one end closed) in the vicinity where the earwigs
congregate and they will hide out inside the tube. To "evict" them, simply
take the tube and quickly shake the inhabitants into a bucket of soapy
water.
