Josh from Florida writes

Is it ok to Mix Bifenthrin and permethrin together also with a IGR (NyGuard) for a lawn application. To have

the permethrin for the fast knockdown and the bifenthrin for longer residual and the IGR to break the flea and other life cycles. Or should I only use the bifenthrin. I dont want the two chemicals to work against each other and have negative results. Thanks

Answer:

We would not recommend mixing Bifenthrin and Permethrin together. The Bifenthrin mixed with an IGR is effective as well as mixing Permethrin with an IGR, such as NyGuard. Nyguard does have a residual for 4-5 months. With fleas, keep in mind that multiple applications are needed for them to be eradicated. After the first application, a follow up treatment should be done every 14 days until the fleas are gone.
