This is the time of year when most people find that earwigs are a problem. This then is the time to focus on controlling them. Dept. of Agriculture knows about when the females open up the nests. The most effective way to control earwigs without insecticides is the use of trapping. Again knowing the insects habit makes the use of traps fairly effective.
Earwigs are night creatures.
They feed and move about in the dark. During the daytime they will find areas to hide from the light. Any small crevice or container makes great daytime homes. Traps should be set in the evenings and collected in the morning to remove the captured insects. Make sure holes are large enough to let the earwig in.
