Cigarette and Drugstore Beetles These two small beetles have become common household pests. The adult beetles may be seen at various times of the year, often in early summer. They are good fliers and may accumulate on window or doorsills when they try to make their way outdoors. Besides the nuisance factor of having beetles in the house, both species are considered stored food product pests. The cigarette beetle (Lasioderma serricorne) is destructive to cured leaf tobacco and tobacco products (especially those in storage), but also feeds on dried yeast cakes, seeds, dried botanical specimens, dried fish, leather goods, and even tapestry and upholstered furniture. The drugstore beetle (Stegobium paniceum) feeds on almost anything of vegetable origin, including a great variety of stored foods, seeds, breakfast cereals and the like. It gets its name from the habit of feeding on almost all drugs found in pharmacies. Both species are often found infesting herbs and spices in the home, especially those that have been left on the back of a shelf in storage for long periods of time. Condiments such as dried chili powder, hot peppers, and celery seed are a few of the items in which they are found. Also, such items as dried flower arrangements or seed pictures may harbor an infestation.
