Nippon Wasp Nest Destroyer Foam controls wasps in and around the home. This powerful aerosol will destroy a wasp nest from a distance of over 3m. The spray foams up instantly to thoroughly wet the treated nest. Fast acting with rapid effect on contact. Contains permethrin and tetramethrin. Apply at the first signs of wasp activity. How to Use: Spray in early morning or late evening when the wasps are in the nest. Hold the can upright 3m away from the nest and spray in 3 second bursts to thoroughly wet the nest. Pay particular attention to the nest entrance or where the wasps are seen entering and leaving. A repeat application may be required where the entrance is not readily accessible. Note: If using on painted surfaces, test before use for discolouration before carrying out overall application. Nippon Wasp Nest Destroyer produces a temporary foam coating on the target surface. This would normally disperse after a few minutes.
