Wasp & Hornet Control

Need to know how to control yellow jackets, wasps, hornets or other pests, so you can enjoy your backyard again? Use our wasp and hornet spray to control the problem, indoors and outdoors.

TERRO^® Wasp & Hornet Killer is an entrapping foam spray that coats nests for a complete kill. Its powerful jet spray can reach nests up to 20 feet away, keeping the user a safe distance away from the nest.

The best time to spray for wasp and hornet control is at sunrise or dusk when they are least active. Spray the nest opening until soaked, then spray the rest of the nest. The entrapping foam remains on the nest to kill any returning insects.

When it comes to how to control wasps and hornets from entering your home, spray anywhere they can enter, including gaps around outdoor plumbing and vents, cracks or crevices in foundations, under eaves, and near windows and doorways.
