Which of the following is true about the drugstore beetle?

The drugstore beetle is known for its habits and lifecycle, particularly as an internal feeder rather than an external one. It primarily targets stored products, including grains, spices, and other pantry items, where it can cause significant damage.

The nature of its feeding means that it does not feed externally on larger structures like some other pest species; instead, it bores into products to consume them internally. Understanding this behavior is essential for pest control operators, as it influences both the identification and management strategies for this pest.

The other options reflect characteristics or associations that do not align with the true nature of the drugstore beetle. For instance, the larvae of the drugstore beetle do not resemble those of the furniture beetle, nor does the drugstore beetle display bright red coloration, and its targeting is not limited to animal feed – it affects a variety of stored goods. Recognizing these distinctions is crucial for effective pest management practices.
