Carpet beetles feed on and breed in a very wide variety of grain-based products, as well as a variety of natural fiber products, including some clothing. Most commonly, the adults are small mottled grey beetles similar in shape to the common ladybug, but only about 1/8 as big; the larvae are like a very small, fuzzy brown-striped caterpillar. These beetles are indigenous to the Northwest, so they may fly in from outside and start an infestation. They may also arrive as hitchhikers in products in the egg stage. A very thorough inspection, and careful treatment of a variety of areas, is needed to achieve control of them once they have become established.
