6 Tips for Treating Nests. Treat at dusk or dawn when the insects are less likely to be active. Wear gloves and long sleeves to avoid being stung. Spray Raid® Wasp & Hornet Killer to kill the entire nest. When spraying, make sure you stand away from the nest and not directly underneath.
If possible, avoid tackling a nest on your own. To kill wasps, hornets, and yellow jackets in above-ground nests, use Ortho® Home Defense® Hornet & Wasp Killer7. The jet spray reaches 20 feet above the ground, and the foaming spray traps stinging pests in their nest. Always read and follow the label directions for use.
