The trap is a bag with a pheromone lure that attracts the beetles. When the beetles land on the slippery surface, they fall into the cup or bag and cannot escape.
Traps are set from May through October and are checked regularly throughout the season. Once a beetle is caught, the number and location of the trap is recorded.
