Black Flag 14 Oz. Foaming Aerosol Spray Wasp & Hornet Killer delivers a powerful blanketing foam that effectively kills wasps, hornets, and yellow jackets on contact. This versatile spray also controls carpenter ants, harvester ants, mud daubers, scorpions, spiders—including black widow and brown recluse—and tent caterpillars. Its foaming jet spray shoots a strong stream up to 20 feet, allowing you to treat nests safely from a distance. The formula leaves no oily residue and is non-staining to most home siding, depending on age and cleanliness. For results, test in an inconspicuous area before use and recheck after a few hours.
