How to Mix Permethrin

3 percent solution is used to help control outside flying and crawling pests, such as house flies, mosquitoes, gnats, ants, ticks, wasps, hornets, fire ants and many other insect varieties. The 10 percent solution is used to control insects in turf grass, house plants, trees and shrubs, roses and flowers and so forth.

Permethrin 10 Percent

1. Add the correct amount of Permethrin to the tank of a pump sprayer. The correct amount varies greatly based on the desired results. To treat turf grass against ants, crickets and grasshoppers, for example, mix 1/2 oz. Permethrin 10 percent with 3 gallons water to treat 1,000 square feet.



2. Dilute Permethrin 10 percent with the correct amount of water. The amount of water will vary greatly depending on the insects you would like to treat.



3. Apply the Permethrin 10 percent and water solution at the recommended application rate, which varies from a square footage application rate to a “wet the whole leaf until it drips” application rate.

Permethrin 13.3 Percent

1. Add the correct amount of Permethrin 13.3 percent to the tank of a sprayer. The correct amount depends on the desired dilution rate (0.25 percent or 0.50 percent), which is determined by the application need. For example, heavy infestations require a 0.50 percent dilution rate; maintenance applications require a 0.25 percent application rate.



2. Add either 1 qt. or 1 gallon water to the tank of a sprayer. Close the sprayer tank, and mix the solution thoroughly.



3. Apply at the specified rate for the dilution percentage: 1 gallon treats 1,580 linear feet with a 6-inch spray width.



4. Apply a maintenance treatment whenever the need arises.
