How to Get Rid of Weevils

Weevils are attracted to lights and so for many species of weevils, they will enter the home at night when they see where the light comes through. They will also enter when the conditions outdoors become unfavorable. This is usually when their food source becomes extremely limited near the end of the fall season. They will usually enter the home when they begin to overwinter and they will remain there until the spring season when they leave the house to resume feeding.

Exclusion and Prevention

To have full control of weevil infestations, the primary step is exclusion. Exclusion will mean sealing any cracks or crevices that are large enough to allow them inside the structure. Caulking areas around the structure like window frames and door frames, tops of bay windows, entry points for utility pipes, vents, and etc. is a suggested method for closing all entry points. Closing off entry points should be done before or after weevil invasion so that they are not trapped inside. Exclusion may also involve changing inviting factors around your home. This may include changing the lighting or reducing exterior lighting which is attractive to weevils.

Remove host plants from the area so that weevils no longer have a food source. More often than not, for any type of pest control, getting rid of the food source will make that environment unfavorable and unattractive. For example, getting rid of wild strawberry plants could knock out an entire colony of strawberry root weevils.

Indoor Treatment

Insecticides that have weevils labeled as a target pest will be efficient for weevil control. Liquid insecticides like LambdaStar 9.7% CS or FenvaStar EcoCap all have weevils labeled as a targeted pest. They are liquid concentrates that must be diluted with water before they are applied. Many hand held sprayers will have both the stream nozzle or mist nozzle. For indoors, the streaming option on a sprayer like CHAPIN GALLON SPRAYER can be used to target the door frames and window frames as well as any cracks and crevices. Dust products like Tempo Dust or PyGanic Dust can be applied with a duster like the Bellow Bulb Duster in areas of very little or no contact like the wall void area or under and behind furniture. Dust products have a longer residual time and may be applied every three to five months.

Keep in mind that all product labels should be reviewed thoroughly before any pesticide is applied.
