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.

* 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 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.

This stuff does the job No Need to hire anyone to come out!!
By Sandra 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!!

Flea and Tick control
By Dagmar on August 1, 2011
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.

Surprise a product that works!
By Lynne 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.

By Cru 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"!

By Rick 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 Effective Wasp Removal
July 9, 2013
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.

I live in the North Phoenix / Cave Creek area of Arizona. I noticed no one seems to mention scorpions! I've been using the product for along time. I spray around my shop, house, and garage. This really kills scorpions. I sometime find at least five and depending on the season as many as twenty dead ones every month or so. I highly recommend this product.

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.
June 26, 2010 Haley asked:
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.
August 18, 2010 Jeff asked:
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.
June 4, 2010 Wendi asked:
QCan I use Tengard SFR on tomatoes to get rid of aphids? If so when will it be safe to eat the tomatoes?
Most of the tomatoes at this stage are still green.
August 1, 2010 Bobby asked:
QWhich product is better for subterranean termites, Tengard SFR or Bifen IT?
I know Termidor SC is the best, but I have pets and those two will not hurt pets when dried. I found termites next to my house, and I checked for termite damage. There was no damage. so they must have just started.
ATermidor SC will not hurt animals when it is dry. As a matter of fact, Termidor SC contains the same active ingredient, Fipronil, as the most popular spot on flea treatments for dogs on the market. We recommend using either Termidor SC or Dominion 2L for the most effective termite treatments. Both of those products are non-repellent and both have a transfer effect meaning that the termites cannot tell that the product is in place and will readily walk through it and transfer it back to the colony. Both the Tengard SFR and the Bifen IT will work pretty much the exact same way since they are both synthetic pyrethroids that are somewhat repellent. Neither of these products have a transfer effect.

Kaz from Bernardsville, Nj asked:
QWhat product is good to treat flying moths for my rug store?
We do not recommend treating for this insect with Tengard SFR. If it is a rug warehouse/large area, we would recommend a combination of monitoring traps and a fogger such as Shockwave applied monthly. The Shockwave would help to control any existing pests with both a quick knockdown and an insect growth regulator to help stop reproducing and the traps would help you to know when a new population moves in. You can also consult with some other rug dealers to find out what they have found effective.

Felicia from Irvine, Ca asked:

Terry from New Iberia, La asked:
QI am getting ready to pour a concrete slab for a 20 ft x 24 ft shop. Can I pretreat the ground before I pour?
Also, will it prevent termites from entering & for how long?
A Tengard can be used as a preslab treatment. This treatment will last for about 5 years after the application. Please read over the Tengard product label application instructions to learn how to apply the product for this application.

Tom from Clearwater, Fl asked:
QIs Tengard SFR the best product for indoor treatment of Subterranean Termites?
If this is not the best, which is the best with regards to safety to occupants, especially children? Also, how often should you retreat indoors? Thanks!
A We recommend using either Termidor SC or Dominion 2L for the most effective termite treatments. Both of those products are non-repellent and both have a transfer effect meaning that the termites cannot tell that the product is in place and will readily walk through it and transfer it back to the colony. The Tengard SFR will only kill the workers that contacted the treated surface and is also somewhat repellent. It also does not have a transfer effect. Typically for indoor termite infestations, you need to drill a hole directly into the infested piece of wood and inject the product however you can. You should drill into the exact center of the wood. We do sell a foam product already in a can for termites that is very popular. It is called Termidor Foam and comes ready to go with an applicator tip. It can take up to 90 days to completely eliminate an infestation. Most people just wait and do inspections every so often and only treat when they have an issue
July 10, 2013
Lawrence from Fontana, Ca asked:
QDoes Tenguard kills roaches?
A Yes Tengard would kill roaches and can be used indoors and outdoors. If you have a heavy problem with roaches, consider one of our Roach Control Kits as this would be a much more effective option to control the roach infestation the quickest and cheapest way. Please let us know if you have any other questions.
June 25, 2013
Jesus from Burlington,nc asked:
QIs Tengard SFR effective to treat an infestation of powder post beetles?
A You should use a wood treatment product to treat powder post beetles. Bora-Care is the best wood treatment product available. Bora-Care will penetrate through the wood and kill the larvae eating the wood no matter where they are in the wood. However, it can only be applied to raw wood. It cannot be applied to wood that is painted, stained, or sealed. If your wood is painted, stained, or sealed, then you will need to drill holes and inject Bora-Care or sand the finish off of the wood, treat with Bora-Care, and then refinish the wood. Dominion is not a wood treatment product and will not move through the wood. You should use a wood treatment product like Bora-Care

Mike from Tampa, Fl asked:
QWhat insect growth inhibitor is most recommended for outdoor flea control when mixed with Tengard?
Are there other products that are more effective for outdoor flea control on masonry surfaces and grass surfaces than Tengard? What provides the best residual effectiveness?
A The Tengard SFR is a great product to use for flea control in outdoor areas and you would want to mix NyGuard IGR with the spray. The NyGuard works great on fleas, ticks and many other insects and last longer outdoors than any other IGR on the market. According to the manufacturer it can hold up to sunlight for about 5 months so you would just spray it with the innitial application of Tengard then use the Tengard by itself with your follow up sprays ever 14-30 days. You will typically use 4-8 ml of NyGuard per gallon of water.
May 22, 2013
Michael from Royse City, Texas asked:
QWhat is the best product to kill chiggers
I will be using your Tengard SFR One Shot with an Ortho Dial N Spray hose end sprayer. This sprayer has adjustable settings from 1 tsp to 8 oz. Which setting would be right for lawn control? I might need to go a little heavy because of the country setting I live in.
A When using Tengard in a dial in sprayer you want to set the dial to 1oz per 1 gallon of water for 1000 sq. feet of treatment.

Chris from Glendale, Az asked:
QHow long will Tengard SFR last in sunlight?
We live out in sunny Phoenix. How long will the product last before it begins to breakdown in sunlight?
A Tengard will hold up to sunlight and other outdoor elements roughly 30 days. You could get a longer residual than that but most homeowners need to reapply each month.

Kris from Olive Branch, Ms asked:
QHow much Tengard should I use per gallon of water?
I have a NorthStar 16 gallon, 2.2 GPM, 70 PSI broadcast sprayer. I want to use Tengard to spray my yard (large area) for ants, army worms and other insects.
A For Lawns, mix 0.4 to 0.8 fluid ounce of Tengard SFR in 4 to 25 gallons of water per 1,000 square feet.Use the higher rate for fast knockdown and increased residual control. Dense or excessive(greater than 3 inches) lawn height and arid conditions may require higher volume application rates. Repeat application if necessary. Application in combination with compatible surfactants or wetting agents may enhance penetration.
