Dermestid Beetle Pantry Pest

Dermestid Beetle Pantry PestDermestid beetles in the dog food. 

Thrasher Termite & Pest Control received a baggie of dry lamb meal with a request to identify the things crawling inside. Those crawling things were the larvae of dermestid beetles. These common pantry pests scavenge and feed on animal matter like dried meats, dead insects, hides and woolens, grain and grain-based products. They are especially common in flour, cereals, and other dried products, such as the dry lamb meal. What to do? Throw out infested products, clean your cupboards, and store any new grain or meal in heavy sealable plastic or glass containers. Baggies do not offer enough protection. We’ve seen holes chewed through baggies and other thin plastic wrap. And by all means, call Thrasher Termite & Pest Control to help you get rid of pantry pests and to keep them from coming back.

Dermestid Beetle Larva

Dermestid beetle larva are hairy. In this photo taken through the baggie, you can see lamb meal clinging to the hairs of the larvae. Beetle larva will eat a tremendous amount of food and continue to grow, shedding their exoskeletons many times. They next enter the pupal stage. After pupating, the adult beetles emerge.
