Dermestidae

Pest description and damage These closely related beetles are about 0.125 inch long, brown, and oval. They feed on a wide variety of stored products: cereals, seeds, spices, tobacco, dried fruits and nuts, dried skins, feathers, and preserved animal products.

Management

Locate and destroy the source of infestation. Place infested materials in the freezer for three or four days to kill pests, then discard. Thoroughly clean shelves and storage areas. Attachments for some types of vacuum cleaners are useful in removing food particles that may have become lodged in cracks. Clean surfaces with soap and water. Where freezing and vacuuming are not appropriate or adequate, treatment by a qualified professional may be required.

Use pesticides safely!

Wear protective clothing and safety devices as recommended on the label. Bathe or shower after each use.
Read the pesticide label—even if you’ve used the pesticide before. Follow closely the instructions on the label (and any other directions you have).
Be cautious when you apply pesticides. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use.
