Spray wasp nests with Black
Flag® Kills Wasps, Hornets, Yellow Jackets & Scorpions. Spray in
early morning or late evening when insect activity is low. Soak the
nests with the spray, and do not stand directly beneath the nest
during treatment. Avoid any wasps that fall from the nest after
treatment. The nest can be safely removed 24 to 48 hours after
treatment.
Prevention tips
It is very difficult to prevent wasps from building nests around
your home. Screen attic vents to prevent wasps from building nests
in the attic. At the first signs of activity, spray small nests.
Check the nest after 24 to 48 hours and if no activity is observed,
then the nest can be safely removed.
