How long does a treatment of Permethrin SFR last?

I will be using it on the exterior of my home in Arizona for arachnids and wonder how often I would need to retreat the area to remain pest free.

Answer:

Since Permethrin SFR is an oil-based product it is going to be more prone to break down in the extreme heat and sunlight in your area faster than other products. You will likely have to reapply the Permethrin every 30 days to keep insect populations under control and have a strong residual still on the surface. We would suggest when you get ready to order more product in the future going with something better designed for your environment like Cy Kick CS or Onslaught FastCap which will also likely give a better control over arachnids and other pests they feed on due to their encapsulation.
