Weevils are bugs that typically eat plants. There are more than 60,000 species in the world, most of which belong to the family Curculionidae, and they are found across the United States. With so many species around, it can be difficult to know how to kill weevils or how to handle a weevil infestation.

Preventing weevils

Outdoors, weevils can also be treated using certain types of nematodes, which will eat the larvae of vine weevils. The Royal Horticultural Society suggests the following types:

Weevil infestations

Once inside a home, weevils will continue to search for moisture, according to the University of Minnesota Extension. Homeowners should look for them in bathrooms and around sinks, and in other areas where water or moisture is present. If found, the Extension recommends a few simple steps to remove them:
