A weevil infestation in your home can cause concern, especially regarding the integrity of your stored food products.

Here are some signs that may indicate the presence of weevils in your living spaces:

  • Visible Weevils: The most obvious sign of an infestation is seeing the weevils themselves, either crawling on surfaces or within food products.
  • Damaged Food Packages: Weevils feed on or chew through cardboard and thin plastic to access food.
  • Weevil Droppings: Usually dark brown or black and very small, they might be found in a scattered pattern or clumps.
  • Presence of Larvae and Pupae: Besides adult weevils, your food products might contain larvae (small, legless, white grubs) or pupae.
  • Unexplained Powder or Dust: As weevils eat through grain kernels or other foods, they can leave behind a fine, flour-like powder.
  • Off Smells: Infested food products can start to smell musty or off due to the presence of weevils and their waste products.
  • Decreased Quality of Stored Foods: Infested foods may appear discolored, degraded, or contaminated.
