Managing Earwigs in the Garden

In small numbers, earwigs are beneficial, feeding on soft-bodied pests like aphids. But in large populations, they damage flower petals and corn silk. They're nocturnal, hiding by day under wood, pots, and debris.

Trapping

• Place loosely rolled newspaper under shrubs or among flowering plants in the evening; collect and dispose of paper and earwigs in the morning.
• Sink low containers (e.g., tuna cans) into the ground around the garden; add ½ inch of vegetable oil. Earwigs fall in; collect each morning.

Chemical Controls

Earwig baits typically contain carbaryl or propoxur. Some include fish oil as an attractant—avoid these if pets might be drawn to them.
