Found Tiny Bugs in Your Flour or Pantry? Here Is How to Get Rid of Weevils for Good

Tiny dark insects moving through a bag of flour or rice can make an entire kitchen seem contaminated. But grain weevils are a common household problem, and their presence does not mean a pantry is dirty.

The pests often enter homes as hidden passengers in factory-packaged food. They can be found in flour, rice, pasta, cereals and even spices. The problem may remain unnoticed for weeks as the insects reproduce inside closed cupboards.

A grain weevil is only a few millimetres long and ranges from reddish-brown to black. It has a long, narrow snout, which the female uses to bore into a grain, lay an egg and seal the opening. The larva feeds inside the grain before emerging as an adult. One female can lay up to 400 eggs, allowing an infestation to spread quickly.

In flour, the insects are more often flour beetles, which are close relatives that prefer milled grains. The distinction does not change the basic response. The pests are not considered dangerous to human health. They do not bite or sting and are not known to spread disease, although they can destroy food and create a mess.

The first step is a complete cleanout of the pantry or kitchen cupboards. Remove jars, tins, packets, boxes and bags, then inspect everything for adult insects, larvae, webbing or unexplained flour-like dust. Because weevils can penetrate paper and thin plastic packaging, any food that appears suspect should be discarded.
