Cricket Behavior and Diet
Crickets are opportunistic omnivores. They feed on live, decaying, or dead plants, their fellow pest insects, and fabrics. Most crickets are nocturnal, and many chirp loudly to attract mates at night. They seek out dark, humid, and warm locations.
Most crickets become a pest hazard in autumn. They may also attempt to leave your building in spring when outdoor temperatures rise. Crickets can also reproduce indoors, so you may continue to see them all winter during an infestation.
Signs of a Cricket Infestation
Crickets chirp to attract mates at night. Their chirps are loud, so chances are, if you have crickets… you’ll hear them. Look for large feeding holes in different types of fabric such as wool, cotton, silk, or leather.
House crickets lie on flat surfaces in damp, dark areas. If you have a significant infestation, you may notice “frass,” which is dried excrement, building up around these surfaces.
