Beetle Blaster is a NON-chemical trap for trapping and monitoring Aethina Tumida The trap should be placed between the frames as shown in the photo; multiple traps can be inserted depending on the infestation or the size of the Beehive.The bees try to drive away the beetle that tries to hide in the traps attracted by the dark entrance holes; it is thus trapped in the liquid inside (about 25-30 ml of mineral oil, apple cider vinegar or vegetable oil).It is recommended to keep the trap for no more than 2 weeks and monitor.Once the trap is full remove it by lifting it with a lever on all sides and slightly widening the frames to facilitate the operation.
