Q&A Home

Sandy writes,

Can I use this on the perimeter of my house one week after applying Ortho Home Defense?

Would the two interact or neutralize the Demand CS? How long do I need to wait?


There wouldn't be any problem using Demand CS after using Ortho Home Defense. While each product contains a different active ingredient both products are from the same class of insecticides, synthetic pyrethroids, and they will not counter act each other. You should wait at least 7 days before applying Demand CS to areas where you applied Ortho Home Defense.
