I need to kill wasps on my property, and I plan on using Permethrin SFR mixed with Cyper WP. When mixing these two products together, should I use the recommended amount for each product as if I was using each product alone? I need a quick knock down from the Permethrin, but I also want a good residual from the Cyper WP. What are your suggestions for the amount of each product per gallon of water in a tank sprayer? Thanks!
Permethrin SFR and Cyper WP are both very similar products, and we really do not think you should mix them together or need to. Cyper WP does have a slightly longer residual than Permethrin SFR, but it also has a fast knockdown just as good as the Permethrin SFR. Typically, you would mix one ounce of Permethrin SFR with a gallon of water and one scoop of Cyper WP with a gallon of water (the Cyper WP comes with a scooper since it is a powder).
