Tengard SFR, manufactured by UPI, is a professional-grade insecticide that eliminates subterranean termites and other wood-infesting insects within 14 days of application.
It is formulated with the active ingredient permethrin 36.8%, which overexcites the pest's nervous system, leading to paralysis and death. This all-in-one insecticide targets indoor and outdoor pests, like silverfish, and resistant termites in residential and commercial structures.
Tengard SFR offers multiple forms of pest control in various application sites without producing a strong, foul odor. One quart of this product creates up to 20 gallons of finished solution to control invasive pests infesting lumber, foundations, basements, and more.
Tools Needed
You will need a hose-end sprayer, backpack sprayer, handheld pump sprayer, or professional skid sprayer.
When licensed professionals use trenching to control subterranean termites, a wheelbarrow and the proper dirt-digging or trenching tools are needed.
We recommend using a hose-end sprayer or handheld pump sprayer when DIY homeowners want to eliminate various insects from lawn areas.
How to Use
- Step 1: Determine how much Tengard SFR to use by measuring the square footage of the treatment area. To do this, measure the treatment areas' length and width in feet, then multiply these together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acre). Depending on the pest, use 0.9 to 1.8 fl. oz. of Tengard SFR per 4 to 25 gallons of water per 1,000 sq. ft. of ornamental plants. For ornamental trees, apply 1 to 5.35 quarts of product per 100 gallons of water. For lawns, use 0.4 to 0.8 fl. oz. of product per 4 to 25 gallons of water per 1,000 sq. ft. Refer to the label for specific application rates and restrictions.
- Step 2: Fill your selected sprayer halfway with water and then add the measured amount of Tengard SFR to the spray tank. Fill your tank the rest of the way with water and shake it to mix well. You're ready to spray.
- Step 3: Apply the Tengard SFR mixture to the target areas for maximum control. For a broadcast application, adjust the nozzle to a fan spray, and for cracks and crevice areas, adjust the nozzle to a pin stream. Reapply the product every 2 to 4 weeks, depending on the targeted pest and application area.
Where to Use
Tengard SFR may be used as a spot treatment in crawl spaces and indoors for carpeting, wood, tile, concrete, or other structural building materials as a crack and crevice injection or paint-on application. It may also be applied to interior plantscapes and landscape ornamental gardens, including parks, lawns, and grounds.
Other than applications to building surfaces, this product's outdoor applications to impervious surfaces such as sidewalks, driveways, patios, porches, and structural surfaces (such as windows, doors, and eaves) are limited to only spot, crack, and crevice applications only.
Tengard SFR can control listed pests on ornamentals, lawns, trees, shrubs, and vines in landscape areas around residential, public, institutional, commercial, and industrial buildings and on plants intended for aesthetic purposes in interior gardens and landscapes.
As a surface or space spray in livestock premises, apply this product to dairies, barns, feedlots, stables, poultry houses, swine and livestock houses, animal hospitals, pens and kennels, and outside meat processing premises.
This product may be used only on fruit and nut trees, such as almonds, apples, cherries, filberts, peaches, pears, and pistachios around residential sites.
Do not apply to commercial fruit and nut trees.
When to Use
Apply Tengard SFR as a preventative treatment to keep various pests from finding their way indoors, particularly in the spring and summer months when pest activity is highest.
The time between treatments depends on the type of surface area where the insecticide will be applied and the targeted insects being controlled.
Safety Information
Tengard SFR is safe to use around children, pets, and livestock 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 it on cats.
Do not use on dogs under twelve (12) weeks old. Sensitivities may occur after using any pesticide product on pets.
Allow treated areas time to completely dry before re-entering.
Special Considerations
Tengard SFR can only be used by licensed professionals as a termiticide to control subterranean termites, as an insecticide to treat pre-construction lumber and logs, and to use on buildings or structures.

| Keith's Pro Tips | "To use Tengard SFR as a broadcast spray on lawns, apply with a hose-end sprayer to cover a lot more area quickly. Add the proper amount of concentrate to the reservoir, attach it to the water hose, and apply the product evenly on desired areas. Always apply at the end of the lawn and work your way back without stepping on treated areas." |
