To remove a wasp nest, knock it down if it is in its early stages, spray the nest with insecticide, and remove the nest manually by trapping it in a garbage bag. The degree of difficulty varies depending on the severity of the infestation.
- Knock new nests down
If you notice a new nest forming around the beginning of spring, it is usually safe to knock it down with a long object such as a broom. This should encourage the wasps to find a new place to build a nest. Avoid knocking down nests with wasps nearby.
- Remove the nest manually
To remove the nest manually, wait until night when the wasps are not as active. Take a heavy garbage bag, wrap the nest in it, and cut down the nest. Seal the bag tightly, and then either place the bag in a sunny area if it is hot out, or put it in the freezer to kill the wasps. Exercise extreme caution when removing wasp nests manually.
- Spray the nest with insecticides
If a wasp nest is too active to knock down or remove manually, go to the store and purchase an insecticide made specifically for wasps. There should be a single opening in the nest where you spray the insecticide, which kills the wasps, allowing you to safely remove the nest. Wear long sleeves, a face mask and protective goggles to prevent wasps from stinging you while you spray, and follow the manufacturer's instructions closely.
