You can use Permethrin SFR, but it will NOT kill wasps on contact. The wasps/bees will die, but not immediately. It can take a few minutes for them to succumb to the product. Permethrin will help to deter them from nesting in areas it has been sprayed. Wasp Freeze is your best choice if you are looking to knock down wasps instantly.
