Although weevils are not necessarily dangerous or harmful to humans or pets, they are a nuisance. Unfortunately, by the time you spot them, there’s already an infestation – which means you’ll want to get rid of them. as soon as possible.

To learn more about weevils, how to quickly get rid of these unwanted visitors and keep them out, we teamed up with urban entomology expert Changlu Wang, Ph.D., from Rutgers University, who focuses on biology, ecology and urban pest control. Follow our guide below for everything you need to know about how to get rid of weevils.

What are weevils and how do they get into the house?

A weevil is a member of the beetle family and they are tiny insects that are virtually invisible to the naked eye until they mature. There are different types of weevils, and the type that invades your pantry feeds on dry products such as grains, rice, beans, grains, seeds, nuts and more.

According to Wang, they can fly into your home or enter through contaminated food. Weevils can also lay their eggs in dry products like grains, rice, beans, etc., which means that it is possible to buy food from the store that already has weevils in the bag.

Although you should inspect every bag of food before you buy it for open or torn wrappers, it is almost impossible to spot eggs or insects until they are fully developed and have become a problem. .

You’ll know you have weevils if you spot tiny brown bugs in your dry produce or around food containers. Weevils are particularly easy to spot in light-colored foods like rice and light-colored grains. Other signs that you may have weevils are “damaged packaging or fine dust on the inside or outside of food containers,” Wang says.

How to get rid of weevils

There is no need to panic if you spot weevils in your pantry, as they are generally harmless, but you will want to get rid of them quickly. Wang states that although weevils usually damage food, some people may experience an allergic reaction when exposed to large numbers of beetles.

It’s best to try and prevent weevils first, but even with precautions, it may not be entirely possible to prevent them completely. While getting rid of weevils is not difficult, it can be time consuming and tedious. Here is what you need to do:

  1. “Throw out any infested food,” Wang advises. If you suspect any open or unopened packages that might have or had weevils, it is best to get rid of them. Also, be sure to check nearby containers, even if they haven’t been opened. Weevils can chew on cardboard and plastic, which means they can also get into unopened food packages.
  2. Get rid of excess food packaging such as cardboard boxes if the food is in an airtight bag that has not been contaminated. Weevils can hide in packages and reappear later.
  3. “If you are trying to collect food, put the items in the freezer for a few days or lay the food out in the hot summer sun, if that’s okay, then store them in a sealed container, ”Wang recommends. If you are unsure if it can be picked up, it is best to throw the item away.
  4. After getting rid of the affected foods, you will want to thoroughly clean your pantry. Take everything out of the pantry and vacuum the shelves, including cracks and crevices where weevils can hide. You’ll want to throw out the vacuum bag or throw the contents of the vacuum outside, clean and sanitize it before you bring it back inside.
  5. Wipe the shelves with warm soapy water or disinfectant spray then wipe again with white vinegar, known to kill weevils.
  6. Clean up all unaffected items such as cans or containers before returning them to the pantry.
