I used this 10% solution diluted in my 32oz Ortho Dial-n-spray to get the perfect 4-6 week yard spray for mosquitoes in my yard. I used to be able to buy a Permethrin based spray at Menards, but they stopped selling it. The alternatives just don't work as well or as long.This concentration diluted in my hose sprayer to the same concentration works great and keeps my backyard very livable all summer (a few applications every 4-6 weeks).I wrote up the mix concentration and instructions on how easily do it on a blog post at:[...]Essentially use 2.5 ounces of this 10% Permethrin solution (this stuff), fill the 32oz. dial-n-spray (or any other 32oz hose sprayer) with water, and set the delivery rate on the dial-n-spray hose sprayer to 2oz/gallon of water. Then spray your yard area. This mix covers about 5,000 square feet of yard very nicely. It only takes about 15 minutes to do my backyard.
