If earwigs become pestiferous there are several effective organic methods that can be used for getting rid of them. Remove garden debris and excessive mulch where earwigs are living and breeding. Since earwigs seldom fly, a sticky band of Tanglefoot Pest Barrier around the trunks of trees, shrubs, and woody plants will prevent them from reaching the leaves and fruits on which they feed. Another favorite remedy is to spread diatomaceous earth where they are apt to crawl. Make applications in late spring about a week apart, and treat the soil around the foundations of houses, along walks, fences, and around trees. If pest numbers become intolerable, botanical insecticides should be used as spot treatments or crack and crevice sprays.
Tip: Trap earwigs by placing rolls of damp newspaper or burlap bags in areas where they are found. Collect and dispose of pests the following day.
