Warehouse Beetles, known scientifically as Trogoderma variabile, are destructive pests notorious for infesting stored food products and causing damage in warehouses, homes, and grocery stores.
Identification of Warehouse Beetles
Warehouse beetles are small, typically around 2-3mm in length. They are elongated oval in shape and possess a dark brown or black color, often with a mottled pattern of lighter markings. The beetle’s body is covered with fine hair-like structures, which give it a fuzzy appearance. They have a distinctive set of wings covered by hard, protective cases called elytra.
Larvae are similarly small, white to cream-colored, and covered with long hairs. The last two segments of the larvae carry tufts of hair that resemble a ‘V’ shape.
Life Cycle and Behavior
Warehouse Beetles undergo a complete metamorphosis, progressing from egg to larva to pupa, and finally to adult. Depending on environmental conditions, the entire lifecycle can last several months to over a year. These pests are known for their aggressive feeding habits, with both adults and larvae capable of causing significant damage to stored products.
