Beetle Blaster is a plastic device inserted between frames in a hive to trap Small Hive Beetles (SHB) and thereby protect healthy honeybee colonies. It also acts as a very effective sentinel device. The trap, 23 cm long and 3.5 cm deep, is designed to fit neatly between outer frames in a hive. Each Beetle Blaster can contain about 25ml of vegetable oil which acts as the trapping fluid. The holes in the top of Beetle Blaster are big enough to allow SHBs to enter, but cannot be accessed by honeybees.
