Permethrin SFR 36.8%, manufactured by Control Solutions Inc., is a broad-spectrum insecticide designed to provide a quick knockdown and residual barrier for about 90 days indoors and 30 days outdoors to control over 75 different types of insects.
This permethrin- based insecticide falls under the category of pyrethroids, meaning it contains a synthetic chemical that safely imitates the actions of a natural chrysanthemum flower but has longer residual effects.
Permethrin SFR 36.8% is a diverse, economical, and efficient insecticide that destroys bugs like mosquitoes, flies, spiders, and others. With one simple application, this product eliminates invasive insects like bed bugs indoors, ensuring complete pest control.
Tools Needed
To apply Permethrin SFR 36.8%, a hand pump sprayer, backpack sprayer, skid sprayer, or ULV fogger is needed. A hand pump sprayer or backpack sprayer is suggested for small surface treatments and cracks and crevice treatments.
For treating flying insects such as mosquitoes or flies, using a Permethrin SFR with a ULV fogger is ideal. Professional pest controllers will have access to skid sprayers to treat larger areas.
How to Use
- Step 1: Determine how much Permethrin SFR 36.8% to use by measuring the square footage of the treatment area. To do this, measure the treatment area's length and width in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acre). The typical rate of Permethrin SFR for treating in and around the home and yard is a 0.5% emulsion of concentrate, which is 1.67 fl. oz. of Permethrin SFR to 1 gallon of water to cover 1,000 sq. ft. For example, if you measured your treatment area and calculated 2,000 sq. ft., you will need to mix 3.33 fl. oz. of Permethrin SFR in 2 gallons of water.
- Step 2: Pour one-third of the amount of water into the spray tank and then measure the amount of Permethrin SFR 36.8% required according to the product label. Fill your tank the rest of the way with water, then mix or agitate.
- Step 3: Apply the Permethrin SFR 36.8% solution to the desired areas using a fine/coarse low-pressure nozzle setting. Wait for the treated areas to dry before entering.
Where to Use
Permethrin SFR 36.8% is excellent for indoor and outdoor use. It can be applied around the perimeter of building structures, cracks and crevices around doorways, windows, weep holes, and wall voids. Permethrin SFR can be used on ornamentals grown in interiorscapes, for perimeter insect control on lawns, ornamental trees and shrubs around residential, institutional, public, commercial, and industrial buildings, parks, recreational areas, and athletic fields, treatment of pre-construction lumber and logs (by licensed pest professionals only), and for use on buildings and structures.
When to Use
Use Permethrin SFR 36.8% when treating an insect infestation in or around your home. It is also a great product to use as a preventative perimeter treatment to keep pests out of homes and building structures, as it leaves an effective residual barrier.
Safety Information
Permethrin SFR 36.8% is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Do not use on cats.
Except when applying to pets, do not allow others to enter until sprays have dried.
Special Considerations
Permethrin SFR 36.8% does give off an odor that lasts for several hours, so make sure indoor areas are well-ventilated. This is a professional-grade termiticide and should only be used by those who are licensed to treat termites.
