Black Flag 15oz Commercial Wasp and Hornet Killer
- Gives rapid contact kill and residual kill of insects returning to the treated nest
# Commercial strength # Eliminate nests of wasps, hornets and yellow jackets both indoors and outdoors
Spray in early morning or late evening when insect activity is low. Direct the spray towards the opening of the nest and thoroughly soak the opening, but do not destroy the papery envelope of the nest when treating. Do not stand directly beneath the nest during treatment. Avoid any hornets that fall from the nest after treatment. Check the nest after 24 to 48 hours and if no activity is observed, then the nest can be safely removed.
