Stored Product Pest
Stored Product Pest are exactly what they sound like, they thrive off of stored products, also commonly known as pantry pest. There are three major insects associated with this category but it pretty much includes anything that thrives off of the groceries in your pantry.
Weevils only infest whole kernels of grain, commonly found in popcorn, seeds, Indian corn, and bags of beans. Even though they are mostly found in agricultural grain storage facilities they do on occasion infest homes.
Indian Mill Moths
Indian Mill Moths are one of the most common stored product pest found in homes. Indian Mill Moths prefer to feed on flower and meal but will also feed on whole grains, dried fruits, nuts, chocolate, crackers, biscuits, dry dog food, bird seed, and red peppers. Their larvae are commonly identified by the silk webbing found over the materials from which they feed.
Saw-toothed Grain Beetles
Saw-toothed Grain Beetles commonly feed on flour, bread, breakfast cereals, macaroni, dried fruits, nuts, dried meats, sugar, dog food, and biscuits. Saw-toothed Grain Beetles generally aren't noticed until the infestations becomes advanced and the mature beetles can be seen scurrying around the pantry.
