Permethrin SFR 36.8% should only be applied once every four weeks. It does take time for the product to work after applied. It would also be a good idea to incorporate an insect growth regulator (IGR) such as Archer IGR for complete control of ticks. All of these products are pet safe if used as directed. Pets need to be kept out of the area being treated during application and until everything is completely dry.
Please look over our Tick Control Guide for more information on treating and preventing this pest.
Permethrin SFR 36.8% could potentially kill beneficial insects including nematodes if they contact a treated area.
When using Permethrin SFR 36.8% for mole crickets the product label states you use 0.4 – 0.8 fl. oz. 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. If you’re using the higher rate of 0.8 oz per 1000 sq ft, that would require 35.2 ounces for an acre. 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.
Yes, you can use Permethrin SFR on horses for horse flies. Per the product label: For use on Horses to control:Horn flies, face flies,stable flies, house flies,horse flies, black flies,eye gnats, mange mites,scabies mites, ticks, lice and fleas: Use ¼ fl. oz. to 1 pt. water, 0.6257% AI. Low pressure spray. Application: 1-2 fl. oz. spray per animal. Spot treat back, face, legs tail and ears.
Since Permethrin SFR is labeled for use indoors as a crack and crevice spray, you could potentially use it as part of a carpet beetle treatment program. We recommend adding an Insect Growth Regulator (IGR) when treating for carpet beetles, such as NyGuard IGR. You could also use a ready-to-use product like NyGuard Plus which has both an insecticide and an IGR in one product. A better choice for use in the drop ceiling may be an insecticide dust, though, since it is a dry product that would not damage the tiles, and a dust lasts much longer than a spray in void spaces like a drop ceiling. Delta Dust can be used in a drop ceiling for carpet beetles and other crawling insect pests there. Or you may consider our Carpet Beetle Control Kit which includes the NyGuard Plus, CimeXa Dust, and glue traps.
Be sure that you have located and removed the source of the infestation as well. We have more tips in our Carpet Beetle Treatment Guide here.
Permethrin SFR 36.8% is labeled for mole crickets. The labeled rate is 0.4 – 0.8 fl. oz. 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. If you’re using the higher rate of 0.8 oz per 1000 sq ft, that would require 35.2 ounces for an acre.
Yes, you can use Permethrin SFR with an IGR such as Nyguard IGR.
Permethrin SFR is only labeled for mosquito control on livestock premises. A better product for mosquito control outdoors is Talstar P and it can be IGR such as Tekko Pro to help sterilize the adults. It is our most popular product for mosquito control and would be a better option. It is a liquid concentrate that you mix with water and apply using any hand pump sprayer or backpack sprayer. You will mix 1 fl oz of Talstar and 1 fl oz of Tekko Pro per gallon of water. The key is to apply it to all shrubs, trees, and other foliage around the house or patio where you are trying to provide relief. It should be directed not only on top of the leaves and plants but on the underside of the leaves as well, which is where the mosquitoes like to hang out. It should be applied every 30 days for optimum control.
Permethrin SFR 36.8% is not specfically labeled for clover mites. Bifen IT would be a better option.
Yes, Permethrin SFR 36.8% can be used for carpet beetle larvae. You will need to use 1 2/3 fl. oz. for each gallon of water to get a 0.5% ratio. When using this product for carpet beetles the label states to apply the spray evenly to rugs, carpets, along baseboards and edges of carpeting, under carpeting, rugs and furniture, in closets, on shelving, and wherever else these insects are seen or suspected. For the best control of immature stages, we recommend adding an IGR (Insect Growth Regulator) to your insecticide, such as NyGuard EZ1.
You do not need to apply insecticides such as Permethrin SFR before insects are active, which is usually when you get consistent daytime temperatures of about 55-60 degrees. If you tend to see overwintering pests like stink bugs or boxelder bugs, then keep an eye on your weather forecast and apply as soon as you get a jump in temperatures on a sunny day.
You will use 0.4-0.8 oz of Permethrin SFR 36.8% per gallon of water per 1000 sq ft. Use the higher rate for fast knockdown and increased residual control.
Permethrin SFR 36.8% is not not labeled to be applied on any edibles. Anything sprayed should not be harvested for consumption and should be discarded.
Permethrin SFR 36.8% can be applied to cattle. For treating flies/lice, you will apply 4 fl oz per 2 1/2 gallons of low pressure spray or 1/2 fl oz per ear for ear tick. It can also be applied at the rate of 4 oz per 25 gallon (treats 50-100 heads). For scabies, mange, lice and ticks you will wet the animal thoroughly and repeat applications in 10-14 days. For a backrubber/self oiler, you will add 4 fl oz to 10 gallons of diesel oil or suitable mineral oil. Please refer to Pages 47 & 48 on the product label for specific mixing and application instructions prior to use.
Permethrin SFR 36.8% is a synthetic pyrethrin like bifenthrin so they would work comparably. Dominion 2L would be a good option to use for chinch bug control and is a neonicotinoid and systemic so is absorbed by the roots that these bugs feed on. Best applied before they are active so it has time to be absorbed.
Per the product label, when treating for termites, you will use the 0.5% solution rate, which is 1 2/3 oz. of Permethrin SFR per gallon of water. Please refer to the label for complete application instructions.
Permethrin SFR 36.8% can be used on ornamentals such as flower beds as directed on the product label.
Permethrin SFR 36.8% is not labeled for use on container plants so we cannot recommend it. We would recommend something like Bifen IT instead which is known for being super gentle on plants and can be used as a soil drench. The best option with fungus gnats though is to allow the soil to dry out completely as this will kill any larvae in it.
Permethrin SFR 36.8% will kill scorpions that come in contact with it. However, a more effective product would be Onslaught Fastcap which is specifically designed for scorpions and other insects that are harder to kill. Onslaught FastCap is a unique insecticide that has an encapsulated pyrethroid plus prallethrin for quick knockdown. The encapsulation really helps products to last longer in the heat and sunlight in desert environments better than the Permethrin SFR would.
Permethrin SFR can be applied anytime insects are active. We would recommend treating in the morning or later in the evening in the warmer months. This product is a great product choice for treatment outdoors for fleas and ticks. Adding an IGR like Archer IGR impedes the insect's reproductive cycle. These products should be applied once every two weeks. Please take a look at our Flea Control Guide for more information.
