Permethrin for Pants, Yard, and Dogs

Permethrin (aka pyrethrin) is a very old, and very safe insecticide, once made from chrysanthemums and now formulated synthetically. I use pyrethran/permethrin dog shampoos to keep my dogs flea- and tick-free during the warm months, and a spray bottle is in the truck to keep ticks off my pants if I’m going through tall, thick brush. Pyrethran/permethrin is so safe it’s FDA-approved for use inside food factories.

I use already-mixed low-cost pyrethrin dog shampoo bought from Amazon on the dogs.

For the yard and my pants, I dilute agricultural permethrin. If you are going to dilute agricultural permethrin for animals, follow the directions. This particular 13.3 percent mix is diluted 2 oz. to 1 qt. of product in 1.3 to 66 gallons of water depending on the size of the animal, and then is sprayed, dipped or sponged on every two or three weeks.
