- It is best to use Harris Wasp and Hornet Killer in the early morning or late evening hours when the insects are less active.
- Stand a safe distance away from the nest and not directly underneath it. Harris Wasp and Hornet Killer has a “jet blast” trigger that can spray up to 20 feet so that you can still reach the nests while maintaining a safe distance.
- Hold the can upright and point the spray opening toward the nest. Do not allow the spray to contact humans or pets directly or through drift. To do this, make sure you spray with the wind at your back.
- Spray the nest until it is thoroughly saturated. The product’s residual action will continue to kill wasps or hornets that may return to the nest.
- Do not remove the nest for at least 24 hours, and check to make sure that wasp and hornet activity has stopped before attempting.
- To spot treat areas where wasps or hornets have been seen, spray the surface for 1-2 seconds until it is moist, but not to the point of run-off.
- Common places to treat include: window screens, window frames, door frames, patios, under eaves, where pipes or electrical wiring enter the home, cracks and crevices, etc.
