Japanese Beetle Traps

Japanese beetle traps are designed for capturing Japanese beetles. However, they also work well for various other flower visiting scarab, cerambycid beetles, mordellids, etc. The bright yellow color coupled with a floral attractant lure (must be purchased from a lure or pheromone company) serve as a great attractant for these and other insects. Changing and checking a sample is a simple matter of unscrewing a ball jar from the trap and putting another one on the trap. The jars are filled with 70% ethanol. Traps are hung from branches with a string or rope.
