Pest NameDescription 
Cupboard beetleCupboard beetleCupboard beetles are a collection of beetle species that attack stored grain products or household foodstuffs. They range from 1/8 inch in length to a little smaller. They are variously colored, but tend to be brownish. Most of them can fly. Once established in food, populations of these insects can explode and move through the home and infest any exposed food. While some enter from outside, most come in purchased food, particularly dry pet food. These beetles can enter a home in large and disturbing numbers to feed on food, such as bird seed or pet food, which mice or other rodents have stored in wall voids. Beetles commonly found in these environments include: drugstore beetle, sawtoothed grain beetle, merchant grain beetle, cigarette beetle, flour beetle, spider beetle, rice weevil, granary weevil, and carpet beetle. The drugstore beetle is the most frequent offender in western Washington. The sawtoothed grain beetle and flour beetles are probably the major ones in eastern Washington, but weevils are nearly as important.
