They are flying around my hanging baskets. Never had this problem before. I've checked everywhere for nests and don't see any.
Yes, Bifen IT is labeled to treat for wasps, but it is not an instant knockdown. Bifen IT will kill wasps that it comes in contact with it. Retreat after 21 days if signs of renewed activity exist. You may want to consider our Wasp and Hornet Kit which contains the residual insecticide Cyzmic CS, plus Wasp-X to kill insects very quickly when you locate nests.
