Stored Product Insects


Flying insects in your cupboard? Time for Emergency Pest Control


Stored product insects are pesky little types of pests that will invade and destroy any food items you may have stored. Once these pests have taken over a food product, they are no longer fit for consumption and must be thrown out. If you find yourself with a pest problem in your stored foods, then calling in professionals would be in your best interest.
Unfortunately, simply throwing out the affected products isn’t enough and will not solve your pest problem. Once these little buggers have infested your stored products, they will spread like wildfire. It is time to call in the troops, aka pest control specialists, who will be able to identify the offenders and what products and tools will be needed to eradicate the problem quickly and efficiently, as well as offer tips and tricks to prevent future infestations.

If you have found a beetle or moth in your food storage area, but you’re not sure that you have an infestation, it is likely that you do. Finding a beetle or moth is the adult phase of their life cycle, the other stages of the insect’s life span (egg, larval, pupal) can be tough to detect.
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.
So, you might wonder what are some of these insects are taking over your food storage and wreaking so much havoc?

· Flour
· Rice

· Cereals
