The bread bug, biscuit or drugstore beetle is a stored products pest. The name might come from infestations that happened to druggists that user herbs in their potions back in the day. They live inside stored foods that are not kept in secured containers. They are usually found in kitchens and pantries where there may be a lot of spills and crumbs. Because they can also survive for weeks without food, every last beetle needs to be extinguished or they will re-emerge from their hiding places and begin a whole new infestation. Although not really found in drug stores, they are capable of boring through thin aluminium to get at whatever they are interested in eating. The real issue with these beetles is contamination in any product they get into, especially in their larval form as they eat and defecate in the products they have infested. Indications that there is an infestation include adult beetles flying around and holes in packaging where the beetles have emerged and feces in infested items.
