Traps consist of a series of four, eight, or 12 plastic funnels arranged vertically. The traps are made of polyethylene plastic. The conical shape of each funnel allows an unobstructed 360-degree catch radius. Funnel diameter is 8" (20 cm). The downward angle of each funnel causes fast-approaching beetles to be deflected downward into the collecting cup.  Escape is prevented by the baffling arrangement of funnels.  Capture does not rely on sticky surfaces or chemical pesticides.  Beetles are killed through heat and dehydration.  A conical drain in the collection bottle increases drainage and prevents clogging from debris.  A collecting cup without drain is available as a separate item for those using a liquid killing agent. The cups are 4" in diameter and attach by twist lock.

Traps are hung from branches or from rope strung between trees. They are lightweight and collapsible for easy transport.
