This 16-ounce wasp & hornet spray targets and eliminates wasp and hornet nests, ensuring a pest-free environment. Its foam-trapping action kills wasps and hornets on contact, while the powerful jet spray reaches up to 25 feet for effective nest treatment. The water-based foam continues to kill insects returning to the nest for thorough extermination. Safe for use on most ornamental plants and shrubs, it won’t stain most home siding or asphalt shingles, depending on their condition and cleanliness. The formula contains 0.5% Permethrin, a powerful insecticide. For areas with electrical equipment, use Bengal Non-Conductive Wasp & Hornet Killer.
