Permethrin SFR 36.8% - Questions & Answers

You can use PErmethrin SFR in a hose end sprayer as long as it can be calibrated to the required usage rate, though for fleas outside the rate is not set per gallon of water. According to the Permethrin SFR product label: For fleas, ant and ticks in lawns - Mix 0.4 – 0.8 fl. oz. (2.4 - 4.8 tsp) of Permethrin SFR in 4 to 25 gallons of water per 1000 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 surfactantsor wetting agents may enhance penetration

Permethrin SFR 36.8% is very toxic to bees and will harm them if they come in contact with a treated area. We would recommend contacting your local cooperative extension office to find out what is used by individuals in surrounding areas without killing the bees. 

Permethrin SFR 36.8% is labeled for ticks in yards and it will offer some residual effects as well. The Permethrin SFR 36.8% product label recommends that you mix the product with a surfactant to help the product better stick to the foliage that you are spraying.  We also recommend adding an insect growth regulator such as Archer IGR to Permethrin to stop the ticks from being able to develop while you are trying to eliminate the infestation. Do not make spot applications. Treat the entire area where exposure to ticks may occur. Use more water (not more product) when treating areas with dense ground cover or heavy leaf litter. Ticks may be reintroduced from surrounding areas on host animals. Retreatment may be necessary to achieve and/or maintain control during periods of high pest pressure.

The Permethrin SFR 36.8% product label recommends that you mix the product with a surfactant to help the product better stick to the foliage that you are spraying.  Ticks may be reintroduced from surrounding areas on host animals. Retreatment may be necessary to achieve and/or maintain control during periods of high pest pressure. All of your pets should be treated with a product that is specifically labeled for use on pets for tick control.  Permethrin can also be used as a flea/tick dip on dogs.  We usually recommend using Talstar P for mosquito control and it can be used with an IGR such as Nyguard IGR to help sterilize the adults. The key is to apply to the underside of the leaves where the adults lay during the day. The Nyguard will also help with ticks as well. (Exciter is a pyrethrum which causes a faster kill but it is not an IGR).

You can also help by creating a "tick safe zone" in your yard. You should have an area that is at least 9 ft wide between your yard and any wooded area. Trim back trees to allow as much sunlight as possible into your yard. Keep grass as short. Remove as much leaf litter as possible. A clearly defined, well manicured border between your yard and any wooded areas or weedy lots will reduce the chance of ticks infesting your yard.

We also have guides here that can help on treating ticks and mosquitoes.

Yes, you can use Permethrin SFR to control ants in the lawn.  You will mix 0.4 to 0.8 fluid ounce 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.

Yes, Permethrin SFR 36.8% can be used in a mist blower for fleas and ticks.

Permethrin SFR is only labeled for use on livestock such as horses and cattle for lice and would not be used for headlice on children or on people at all.  For treatment on humans, you would need to contact your doctor or pharmacist for the best recommendation.

Permethrin SFR 36.8% is labeled to treat for roaches. We highly recommend one our Roach kits, as it takes more than one product to treat for roaches. 

Yes, Per the product label of Permethrin SFR 36.8% you would use 1 to 2 quarts per 100 gallons of water and apply to the lower branches and trunks prior to asult emergence. Adult emergence varies according to pest species, host trees, environmenta conditions and geographical location. Thprough coverage of bark is required for control.

Permethrin SFR 36.8% would not be a recommended product as a soil drench for Ash Borers as it is not a systemic and will only kill the insects that contact the treated soil.  Dominion 2L is labeled to use on trees to help protect against boring beetles. Treatments should begin in May or June and should be done every year to protect trees from the Emerald Ash Borers. Most people use a 5 gallon bucket or a large watering can to apply Dominion as a soil drench. You will need 0.1 to 0.2 fl. oz. (3 to 6 mL) of Dominion 2L per inch of trunk diameter for trees. It is recommended that you use the higher rate for boring beetles. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per inch of trunk diameter for trees but you may use 1 quart -1 gallon of water per inch of trunk diameter for trees. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred. After the soil drench has been applied you should water it in with at east 1/2 inch of water. Note: Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved. Insecticides applied to the soil are taken up by the roots and trans-located throughout the tree or shrub. Root/soil drenches offer the advantage of requiring no special equipment to apply (other than a bucket or watering can). However, surface layers of organic matter, such as mulch or leaf litter, can bind the insecticide and reduce uptake. Before applying drenches, it is important to remove or pull back any mulch or dead leaves so the insecticide solution is poured directly on the mineral soil. It is also important to keep the soil around the tree or shrub moist for the next 10-14 days after applications to encourage uptake.

No, Permethrin SFR 36.8% is not labeled for chiggers.

We would recommend using Demon Max. This is labeled for chiggers and is oil based as well. The mixing rate is 1 fl oz per gallon of water. This can be used outdoors every 30 days as needed.

Permethrin SFR 36.8% can be used inside and outside for flea control. If treating outside, you will want to apply on a  dry day and have 24 hours prior to a rainfall. We suggest treating with an insect growth regulator (IGR).  Treatments should be performed once every two weeks. Please take a few moments to review our treatment article on How to Get Rid of Fleas for a successful eradication program. 

It is not necessary or  recommended to mix Permethrin SFR 36.8% to Tempo SC Ultra or Malathion. Malathion is not labeled for flea treatments so this would not be suggested for your treatment. We would suggest mixing Permethrin SFR 36.8% with an Insect Growth Regulator (IGR) and a synergist (for a quick knockdown) such as Tekko Pro and Exciter for outdoor applications. We do carry an Indoor Flea Kit that  will work great for interior areas. Please take a few moments to review our article/videos on How to Get Rid of Fleas for a successful eradication program.

Yes, you can use Permethrin SFR 36.8% indoors for fleas.  It cannot be applied to cats.  Cats need to be kept out of the area during application and should not be allowed to return until everything is fully dry.  Please take a look at our Cat Flea Control products to find products that are safe for direct application to cats.

Permethrin SFR 36.8% should be used within 24 hours of mixing with water in a sprayer for the mosot effective control.

We used to carry Dragnet SFR, but FMC (the manufacturer) discontinued it. It was the same thing as Permethrin SFR 36.8. We are not sure if the Dragnet FT (which we didn't carry) is the exact same formulation, but from looking up the label, it appears to be the same percentage of the same active ingredient. Please let us know if there a particular pest you are treating.

Permethrin SFR 36.8% is labeled for flies and may be a good option for you.  You could also use a product like Bifen IT.

Permethrin SFR 36.8% is not labeled for chiggers and may not provide adequate results for you. Onslaught insecticide is labeled for chiggers and can be used both indoors and outdoors as a broadcast spray. Chiggers are not known to infest structures. Chiggers are most likely outdoors in your yard. Many people are lead to believe that the infestation is indoors because they do not feel the effects of the chigger bites right away and then are lead to believe they are being bitten at a later time. Treatments for chiggers should begin in May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. You can also use Onslaught to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors. If you feel strongly that you are being bitten inside by something we would urge you to get a sample of the pest and have it professionally identified by an entomologist. You can find an entomologist in your area by contacting your local cooperative extension office.
