If you’ve ever poured out a cup of flour while baking, only to find it full of little creepy crawlies, you might have a pantry pest infestation. Many of these little insects are so small, you won’t know they’ve infiltrated your cabinets until discovered in a bag or box of food in your kitchen.

Signs You May Have A Pantry Pest Infestation

  1. Damaged pantry foods, usually grain – Adult weevils often eat their way through grains, leaving holes and gnaw marks.
  2. Insect tracks through flour – Pantry pests hanging out in flour will leave small trails of floury dust in their wake when moving to a different food source.
  3. Discoloration in flour and grain – Pantry pests will leave waste materials inside the food they inhabit, leaving it discolored and prone to molding.

Weevil Infestations

The bean weevil is an olive-colored, teardrop shaped weevil with ruddy legs and red antennae. These pests measure about ⅙ of an inch in length. Because bean weevils are so small, most homeowners aren’t even aware they are in their kitchen. The first sign of an infestation is usually several bean weevils flying around your kitchen or congregating near windows or other well-lit areas.

Rice and granary weevils are ⅛ inch long and dark brown with light patches speckling their wings. Our pest exterminators have found granary weevils in homes and businesses from downtown to Shorewood and beyond. These pests feed on whole grains, cereal, beans, nuts, and pasta noodles in commercial, industrial and residential environments.

The confused flour beetle resides in the north long and has a flattened body that makes it easy for them to get into food packages.

If you notice a grayish tint on your grain and flour products, there’s a good chance you may have an infestation.

The drugstore beetle is a reddish-brown to dark brown, sphere-shaped beetle measuring 1/10 to 1/8 inches.

They usually only make an appearance in our area during the warmer months.

Foreign grain beetles feed on moldy, out-of-date grain products and the surface fungi accumulating on wood beams and studs exposed to moisture and may emerge from ceiling light fixtures, electrical outlets, and baseboards. They can be found in older buildings with bad drainage, water leaks, or poor ventilation conducive to fungus and mold growth.

Sawtoothed & merchant grain beetles are brown to dark brown, measuring about 1/10 inches long.
