Some signs you may have a stored product insect infestation are:
· Dead insects, especially near cracks and crevices and on the back of the cupboard. This one is pretty obvious but must be said.
· Damaged packages which serve as a food source – if you find packages with holes in them, there’s a good chance something chewed or burrowed into your food stores.
· Webbing, moth larvae leave a webbing behind as they move through food.
· Food may look discolored from the pests.
