Where do weevils nest?

Weevils don't exactly "nest" like birds; they lay eggs inside their food sources, such as grains, seeds, fruits, or plant stems, often boring a tiny hole to deposit them. Inside homes, they infest pantries, hiding in and breeding within products like flour, rice, pasta, and cereals, which are brought in with eggs already inside. Outdoors, they can be found in gardens, fruit trees, and leaf litter, near or within plants they feed on.

How to get rid of a weevil infestation in a house?

To get rid of weevils, first find and discard infested dry goods, then deep clean your pantry by vacuuming thoroughly and wiping shelves with a vinegar solution, and finally prevent reinfestation by storing new items in airtight containers with bay leaves or cloves.

Weevils get into sealed containers because their eggs or larvae were already inside the food product (like grains, flour, cereal) when it was packaged, hatching later in your pantry, or they chew tiny holes through thin packaging like plastic bags to enter. They don't always get in from outside your home; often, you bring the infestation home from the store, where insects can lay eggs during processing, harvesting, or storage.
