Pantry Pests Identification

Pantry pests can sneak in from connected housing units or outside sources. These pests may be inside packaged food products and you’re bringing them inside your home without realizing it. Once they find delicious food sources, they spend most of their life crawling about in the infested food material.

These pests enjoy a wide range of food for people and pets. They particularly love food items kept in paper containers and left untouched for long periods of time such as dry pet food, powdered milk, flour cereals, dried fruits, grain products, bread, spices, dry cereals, crackers, and other dry goods.

Pantry pests enter the cracks and crevices of drawers and pantries and infest foods. Some families may also lose a lot of money from the large amounts of food that they need to throw away. Consumption of infested foods can cause intestinal problems and stomachache as well.

Signs of an Infestation
