How does the drugstore beetle feed?

The drugstore beetle primarily feeds externally, which classifies it as an external feeder. This means that the beetle consumes its food sources by eating from the outside, rather than burrowing inside. The drugstore beetle typically targets dried foodstuffs, including grains, herbs, and other organic materials found in pantries or stored items.

As an external feeder, the drugstore beetle uses its mouthparts to chew through the outer surfaces of food items, gaining access to the nutrients within. This feeding behavior can lead to significant contamination and damage to food stores, which is a key concern for pest management. Recognizing this feeding behavior is essential for implementing appropriate control measures and preventing infestations in food storage areas.
