Earwigs live for one year. They are primarily nocturnal, and live in damp
dark environments. They would not survive in an arid climate. During the
day, they harbor in dark, damp place, including compost piles, dead plants,
and under mulch or straw.

a light away from the garden. For homeowners, place a light out in the yard,
to attract them away from your house.

to roll up a section of newspaper. Place it on the ground near an infested
plant at nightfall. In the morning, shake out the earwigs into a bucket of
soapy water. Another trap is a tuna can with 1/2" vegetable oil. Adding a
little bacon grease increases the effectiveness of the trap.
