Basic Earwig Trap Design for Bait Tests
SLIDE 20
Baiting Evaluations
–Rolled corrugated cardboard or crumpled newspaper can be used in trap design –Addition of either wheat bran or wheat germ greatly increase capture of earwigs in traps –Vegetable oil in a sunken cup is highly effective for earwig capture
