Outside of Pest Control, you may not hear about these critters very often. You have probably had moths or beetles roaming around your home without knowing it. Food, such as grains, or clothes made of animal fibers, such as wool or fur, attract Stored Product Pests. Even though they can be a nuisance, in the wild these insects serve an important purpose by breaking down biological materials and fibers. There are several different species that fall into this category.
