Like Diana, I sift my flour with a metal sifter if I am concerned about pantry moth larva. I also rinse rice thoroughly before I cook it. Thanks for bringing up this topic. I always rinse any rice.

You can freeze flour to kill the weevils and then sift the flour before using it. I just consumed a whole lot of bugs infested in my beans; just a little bit crunchy. Due to their diets, they are often found outside in gardens or inside in kitchens where food is stored.

But what do weevils eat? There are more than 60, species of weevils in the world. Many of these have very specific food preferences. Weevils that are most often found in homes or gardens can be grouped into one of three categories: fruit and nut weevils, seed and grain weevils or root weevils.

The weevil diet depends on which of these three categories the weevil in and around your home falls into. Fruit and nut weevils are found in gardens, crops and orchards. Common types of weevils that fall into this category include the plum curculio and the acorn weevil.

Its larvae soft, white grubs without legs and white pupae are similar to those of the rice and maize weevil. This weevil cannot fly, so will be found close to the areas it infests. The adults can live up to 8 weeks, during which time the female can lay up to eggs. Partly because of its long life and partly because of its ability to fly, the rice weevil is considered to be the most destructive, but all three weevils can cause extensive damage to stored foods.

When they infest grain that is stored in bins and remains undisturbed, they can completely destroy the food. In the home, weevils can be brought in on packaged foods or they can come in from outside.

Once inside, a population can grow and expand to food items stored nearby if the pests are not controlled. Store grains and other weevil-tempting foods in dry areas, and always throw out any food where you find weevils.

Clear any cupboards where you've found weevils and clean thoroughly before storing food there again, using a vacuum to be sure you've gotten all larvae. You should avoid using chemical treatments to get rid of weevils because most are not safe to use around food. Mutis, Ana et al. Environmental Entomology, vol 38, no. Weevils on Stored Grain.
