How to deal with stinging pests
The best action is prevention. Scout from mid-spring on for small nests. Early on a chilly morning, before wasps have revved up for the day, knock down the nests with a pole, a strong jet of water from a hose, or even your kid’s super soaker—then step on the nest. If wasps set up shop too close to home (especially in wall voids) and you didn’t catch them early, hire a professional to remove the nest.
Before you start outdoor projects, check for nests in trees with holes in them, decks, railings, eaves, the undersides of outdoor furniture, and branches of trees and shrubs.
