Trying to see if Onslaught or Bifen or some mixture would be best to spray outside everywhere to prevent wasps and flying stinging insects. Thank you.
We would recommend using the products included in our Wasp and Hornet Control Kit. Please be sure to review the product labels for more information and complete application instructions. The kit includes Demand Duo Insecticide, which will provide residual control of treated areas, and Wasp Freez,e which is a contact killer. We have very informative control guides that I will link below that offer many helpful tips on treating and preventing these pests.
