What do saw-toothed grain beetles primarily feed on?

Saw-toothed grain beetles primarily feed on dried foods, which includes a variety of grains, flour, nuts, dried fruits, and other stored food products. These pests are commonly found in pantries and can easily infest packaged or loose dried goods. Their ability to thrive on this type of food makes them a nuisance in homes and food storage areas.

Understanding their feeding habits is crucial for effective pest management, as controlling these beetles involves adequately storing food items and inspecting for signs of infestation. The other options listed—fresh fruits and vegetables, meat and dairy products, and wood and paper products—do not provide the necessary nutrients that saw-toothed grain beetles seek, making dried foods their primary source of sustenance.
