How to Use Tengard SFR for a Subterranean Termite Treatment

How to Use Tengard SFR for a General Insecticide Application

How Tengard SFR Works

Tengard SFR is a liquid concentrate insecticide containing the active ingredient Permethrin. Permethrin is a synthetic pyrethroid that is made to mimic the chemical properties of naturally-occurring pyrethrins. When target pests come in contact with the direct spray or dried spray residual, permethrin attacks the central nervous system, causing paralysis and death. Tengard SFR contains a high percentage of permethrin for faster knockdown of target pests and convenient versatility.

Tengard SFR is a broad label insecticide as well as a very effective termiticide for use in and around homes, on lawns and shrubs.

Tengard SFR is professional grade, low-odor product that is labeled to include everything from pre- and post-construction termite treatment, indoor and outdoor pest control, and turf and ornamental applications. More homes are treated with Tengard SFR by professional pest management companies than any other product.

Tengard SFR is safe for children and pets when used as labeled. Areas treated as labeled are safe to return to after area is completely dry. Product should not be sprayed or applied directly to animals, feed, or drinking bowls. Tengard SFR is considered safe for carpeting, furniture and flooring when used as directed.

Tengard SFR may be used to control pests inside and outside of homes and buildings, on lawns, shrubs, bushes, ornamentals, and outside surfaces of buildings, and for post-construction and pre-construction treatments for termites.

Tengard SFR may be applied inside homes and businesses on most nonfood areas, carpeting, pet beds, upholstered furniture, basements, attics, crawlspaces, wall voids, cracks and crevices around sinks and appliances and flooring. For outdoors on siding, wood, grass, bushes, shrubs, ornamentals.

ACTIVE INGREDIENT: Permethrin 36.8%

Application Instructions

Always read the product label completely before use. Shake container well before using.  

* Indoor Treatments: for fleas, roaches, ticks, ants and other indoor pests, only 1 to 1.6 ounces is needed per gallon.

* Outdoor treatments: for fleas, ticks, ants, mole crickets, chinch bugs and other insects, 1 ounce will treat 1000 square feet of lawn.

For subterranean termite treatments, Tengard SFR may be used pre-construction or as a post-construction treatment. For post-construction treatments, use 4 gallons of finished solution per 10 lineal feet of treatment area in a 6 in. by 6 in. trench adjacent to the structure. A continuous zone must be created for complete protection. See our article How to Do a Termite Treatment for more information. See product label for complete directions for termite treatments.

Each quart bottle yields 19 gallons of finished solution for most treatments, or covers 40,000-80,000 sq. ft. for lawn applications. Each 1.25 gallon bottle yields 95 gallons of finished solution for most treatments or covers 4-10 acres for broadcast applications.

Standard Application Dilution Rates / Mixing Ratios:

*1.67 fl. oz. (49 mL)/gal. of water – 0.5% a.i. – termite treatments; broadcast treatment outdoors for nuisance pests

*3.33 fl. oz. (99 mL)/gal. of water – 1.0% a.i. – treatment of preconstruction lumber and logs

*6.67 fl. oz. (197 mL)/gal. of water – 2.0% a.i. – limited pre- and post-construction termite applications

*0.4 to 0.8 fl. oz. (12 – 24 mL) in 4 to 25 gal. of water per 1,000 sq. ft. – lawn applications

*4 to 8 fl. oz. / 100 gallons OR 0.9 to 1.8 fl. oz./ 10,000 sq. ft. – ornamental plants; use sufficient volume of water to adequately cover foliage

*1-5 quarts / 100 gallons of water – ornamental trees; varies with pest

*Use 4 gallons of 0.5% solution per 10 linear feet for termite barrier treatments.

*For horizontal barrier termite treatments, apply to the soil surface at a rate of 1 gallon of finished solution per 10 sq. ft.

For use in the following areas:

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 preconstruction lumber and logs, and for use on buildings/structures. For control of subterranean termites pre-construction and post-construction; lawns adjacent to or around private homes, duplexes, town-houses, condominiums, house trailers, apartment complexes, carports, garages, fence lines, storage sheds, barns, residential structures, commercial and institutional buildings, and other areas where pests congregate or have been seen; plants intended for aesthetic purposes in interior gardens and plantscapes; inside residential homes and the non-food/feed areas of commercial establishments including garbage rooms, lavatories, floor drains (to sewers), entries and vestibules, offices, locker rooms, machine rooms, garages, mop closets, packaged good storage areas and other non-food/feed areas of Food Handling Establishments; in and on buildings and structures used for agricultural purposes and their immediate surroundings; Dairies, barns, feedlots, stables, poultry houses, swine and livestock houses, animal hospitals, pens and kennels, outside meat processing premises; Livestock spray for lactating and non-lactating dairy cattle and goats, beef cattle and sheep, poultry, swine, horses; Companion dogs; Fruit and Nut Trees around residential sites only: Almond, Apples, Cherries, Filberts, Peaches, Pears, Pistachios


For fleas, roaches, ticks, ants, and other indoor pests, use 1 – 1.6 oz. per gallon of water.

Fleas: Prior to treatment, carpets and furniture should be vacuumed thoroughly and vacuum cleaner bag discarded in an outdoor trash container. Evenly apply a broadcast spray at a rate of 1 gallon per 800 to 1,600 square feet to infested areas such as crawlspaces, rugs, carpets, pet beds and other pet resting areas. Avoid wetting or soaking. For crawlspace applications, the applicator must wear a respirator recommended by NIOSH for filtering spray mists and organic vapors. When treating upholstered furniture take care to treat between and under cushions. Pay particular attention to areas which are frequented by pets. Old pet bedding should be replaced with clean, fresh bedding after treatment. To control the source of flea infestations, pets inhabiting the treated premises should be treated with a flea-control product registered for application to animals.

General Pest Control Indoors: Apply to cracks and crevices, as a pinstream, as a fine/course, low-pressure spray, spot application or with a paintbrush. Treat where pests are found or normally occur, such as cracks and crevices in walls, in and around kitchen cabinets and drawers (remove all utensils, foodstuffs, shelf paper and other objects before spraying), along baseboards, behind sinks and around plumbing and other utility installations. Ant infested wood may be drilled and injected with Tengard SFR.


For fleas, ticks, ants, mole crickets, chinch bugs, and other insects, 1 ounce will treat 1,000 sq. ft. of lawn (use ample water as needed for coverage).

*See above for termite treatment details.

Broadcast Treatment for Control of Nuisance Pests: Apply using a 0.5% emulsion as a residual spray to outside surfaces of buildings including, but not limited to, exterior siding, foundations, porches, window frames, eaves, patios, garages, and refuse dumps.

Perimeter Treatment: Apply a band application 6 to 10 feet wide around and adjacent to the structure. Also, treat the base of the structure to a height of 2 to 3 feet. Use a spray volume of 2 to 10 gallons of emulsion per 1,000 sq. ft. If mulch or debris is present, a higher volume application rate may be needed to ensure adequate coverage. Treat the base of the structure to prevent insects from entering the structure.

Companion Animals (Dogs Only): Do not use on dogs under 12 weeks old. Consult a veterinarian before using this product on medicated, debilitated, aged, pregnant or nursing animals. Sensitivities may occur after using any pesticide product on pets. If signs of sensitivity occur, bathe your pet with mild soap and rinse with large amounts of water. If signs continue, consult a veterinarian immediately. Avoid contact with face, eyes, and genitalia. Repeat applications every 2 weeks, if necessary. Mix ¼ fl. oz. to 1 pt. water for low pressure spray. Use 1 to 2 fl. oz. spray per animal. For dip wash, use ¼ fl. oz. to 1.25 gal. water (or 4 fl. oz. to 20 gal. water) and thoroughly wet animal to skin with sponge or rag. Let drip dry.

    5 of 5 Stars  This stuff does the job No Need to hire anyone to come out!!
    By Sandra in San Tan Valley Az on July 17, 2010

    This product works GREAT. I bought this 2 years ago and still have some left. A little bit goes a long long way. I spray maybe 3 to 4 times a year. With AZ heat & Monsoons this stuff does the job. I have a neighbor who sprays for a company and he offered to do my yard front and back. I figured ok why not, I will try once and I noticed critters within a week. I pulled out my trusted Tengard and the critters were gone and haven't been back for 3 months. I love this product!!

    By Dagmar in Blountville, TN on August 1, 2011
    Verified Purchase

    I used the product recently and am happy to say that it really works. This has been a very bad season for fleas and ticks. A CSR recommended this product while I was ordering Precor and I'm glad she told me about it. It is easy to prepare and spray, leaves no aftersmell, residue and any tell tale signs that my home has been sprayed. I could not detect any on the floor, carpet or furniture.

    5 of 5 Stars  Surprise a product that works!
    By Lynne in Deerfield, NH on June 8, 2010

    I have a problem with wood wasp living in my siding. I've had exterminators here and tried self applied products that didn't work. I've been battling this for 3 years. I found this web site and asked for help. Michael is a saint! Knowledgeable and helpful, he had me try this, and daily more are dying. I am thrilled and hopefully this time it is working. Tengard is easy to use and effective! Less expensive than the others I have tried. Easy to apply with sprayer, I also used it to kill wasp nests around the outside of my house.

    3 of 5 Stars  Tengard
    By Cru in Lafayette, LA on October 2, 2010

    This is a great product...just not great for the problem I am having. I am having issues with some type of biting mite. I have not been able to capture one to positively identify it because I don't see them! I applied Tengard to every area of my home and experienced immediate relief. But three days later the problem was back. I can only surmise that the product does not kill the eggs and when they hatch the problem starts up again. The reason I ordered this product is because of the residual killing ability - it is supposed to last for 90 days. Hopefully after a while the newly hatched mites will be killed by the Tengard as well. I suspect there areas in the upholstery they can "hide"!

    5 of 5 Stars  Tengard SFR
    By Rick in Midwest on September 14, 2010

    This is the BIG GUN, a highly effective product but also rather expensive. if you have a pesky pest problem, this is the one to shoot it with. If you're a pro, I'm sure you already know that, but for the average homeowner doing their own general pest control, it's a great product. I use this to control lawn pests like biting ants, chiggers, fleas, etc. and have rarely needed to reapply. I recommend using this when all others have failed, because this one very rarely fails.

    Tengard was recommended by a professional exterminator for elimination of wasps because it is effective and does not require a professional license. We had hundreds of wasps in and around the eves of our house and after one application of tengard, the next day we were down to only one or two and they don't stay around. This stuff works.

February 3, 2011 Tara asked:

QIs Tengard SFR really safe to use around cats?
I've read that permethrin is toxic to cats. Is this only if the product is used directly on them? Can they get sick by coming into contact with permethrin after it has dried? My concern is the cats (and dogs) will possibly get some on their paws and lick them, causing them to get sick. I'm also concerned if I spray the grass and they eat it. What is the difference between Tengard SFR and Permethrin SFR?

AMost synthetic pyrethroids can be toxic to cats if they are applied directly to them or if they are allowed to walk on treated areas before they are dry. That being said, most cats do not have an issue being in a home that has been treated with a permethrin (as long as they stay out of the treated area until it is dry). Most treatments are limited to cracks and crevices indoors, limiting a pets exposure. Also, once the product has been diluted with water there is a very minute amount of the actual insecticide that will be available, usually just enough to kill a very tiny insect, not enough to have any effect what so ever on a mammal of any size. Permethrin used to cause a lot of problems when it was diluted with oil because the application would stay wet and available to the animals. In most cases today, the permethrin is diluted with water, which of course dries very quickly. Permethrin products are used in homes with cats everyday across the country.

QDoes Tengard SFR hold up in rain? Also, how often does this product need to be applied?

AYes, Tengard SFR can hold up to rain. It is important to have 24 hours before the application and 24 hours after the application rain free. As for how often Tengard SFR needs to be applied, that will depend on what type of pest you are treating for and where exactly you are treating. Please read the product label for more information.

QShould I use Tengard SFR to treat a large area for ticks and chiggers?
We are looking to get rid of the ticks and chiggers in a 50 acre grassy area. There is going to be a lot of foot traffic and pets in the area. We are starting to develop the land from pasture into a home and work area.

ATengard SFR would be a great choice for your needs. You will want to concentrate on areas where you have dense brush and long/tall growth. It is also helpful to keep grass and brush cut short to eliminate the habitat of ticks and chiggers.

August 31, 2011 Nils from Morganton Nc asked:

QWhere can we buy Dursban or Thiodan for peach tree borers?
We understand that these are not available for home use and also that Thiodan is sold under another name. What do you have that works as well. We want to spray our trees at the end of August or first of September as this is the time to do this.

AAs long as the peach trees are not already infested with peach tree borers you can use a product that contains permethrin such as Tengard SFR. Unfortunately once the beetles have already infested the bark of a peach tree there are not any viable treatment options. In cases of infestation the general recommendation is to simply protect the surrounding trees with preventative sprays with permethrin products. We do not have any access to Dursban or Thiodan.

QWhat can I buy in NY without exterminator license for Termite control?

A Because NY has such stringent laws, there is a limit to the items that can be shipped to NY. We do have EcoTreat Natural Outdoor Insect Control. It kills and repels termites, as well as various other pests. It is likely that the residual is about 30 days for termites.

QHow does Tengard compare to Dragnet?
Since Dragnet is not going to be made and sold how does Tengard ?

A Both Dragnet and Tengard are still in production, and both products contain 36.8% permethrin. Dragnet is manufactured by FMC, while Tengard is a generic made by United Phosphorous, Inc. The only differences would be in the non-active ingredients, but the basic dilution rates and uses are exactly the same for both products.

November 19, 2014 Angela from Fort Collins, Colorado asked:

QI asked earlier if Talstar P was safe to use on outdoor cushions. The response was it is not to be used on
furniture and what I'm treating for. I am treating for bird mites. I take care of feral cats and they are constantly being infested with bird mites. I am only able to catch one of the cats to treat with Revolution. The cats love to lounge om the cushions. I was hoping for a residual treatment that would be safe to apply to the cushions. If I use DE the cats won't go near the cushions and I want them to be able to as they enjoy sitting on them, in the sun.

A Have you had a proper identification for these pests? It is likely that cats would not carry bird mites. We would recommend getting these identified for sure so that we can give you a proper treatment plan.

March 26, 2014 Alan from Sierra Foothills At 4,250ft Elevation Ca asked:

QIs Tengard or Bora Care best to treat stress trees from beetle invasion? or straight permethrin
We have dozens of trees subjected to latestest CA drought, which are susceptible to beetle infiltration, which is fatal. Tengard has been suggested locally, but from your QA section you mentioned Bora Care is better, but did not mention what is best for live trees. We have a short window to be proactive, and want to make the most informed decision. Also, is straight Permethrin an option? Pro and cons so we can proceed. Thanks

A BoraCare is only labeled to be used on cut wood, not live trees. Tengard SFR is a permethrin based product and would be a great choice for helping to prevent an infestation.  The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations

Terminix used to spray Cyfluthrin.007% as a band treatment; Deltamethrin .05% crack and crevice treatment hand duster; Lambda-Cyhalothrin .045% perimeter band treatment; and boric acid 5%mother earth granular scatter bait. I purchased Tengard from you guys and I was wondering if I needed any of these other chemicals since, thanks to you, I am now doing the pest control on my own. thank you

A Tengard is a 36.8% permethrin, which will kill a broad range of common household pests. It does help to have an insecticidal dust such as Delta Dust (deltamethrin 0.05%) in deeper cracks and crevices as these are traget places that insects like to hide and harbor. Also, if you have a specific pest that is more commonly a problem in your home, knowing that will help us know if you need additional or other products in your treatment.

QWood boring bees in treated wood. Can I spray the wood with something to do away with them?


We have a Carpenter Bee Kit that is our most popular product(s) for carpenter bee control.  The kit comes with a dust and a hand duster to apply in the existing holes.  The dust will kill any carpenter bees that are in the holes and will kill the larvae when they hatch.  After a few days all of the adult carpenter bees that are in the holes will die.  You can patch the holes at this point.  The kit also comes with a liquid concentrate that you mix with water and apply using a one gallon hand pump sprayer.  You should treat all of the fascia boards or any surfaces that the carpenter bees seem to be going after.  This will prevent any new holes.  When a carpenter bee lands on the wood surface to make a new hole, it will pick up the product you sprayed on its body and die when it grooms itself.  Carpenter bees are only around for a short time in the spring, and then again in the fall.  You will have to apply both times of the year and then after 2 seasons there will not be any more larvae in the wood.
