Always read and follow label directions. Spray in early morning or late evening when insect activity is low. Soak the nest with the spray, and do not stand directly beneath the nest during treatment. Avoid any wasps that fall from the nest after treatment.Never attempt to spray individual wasps, especially when in flight.
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. Wasps can sting. Be very careful when using traps and other insect control products
