Permethrin SFR 36.8% - Questions & Answers

Yes, Permethrin SFR 36.8% is labeled for fire ants.  You will use 1 2/3 fl oz per gallon of water. For an acre, it is recommended that you use 32 fl oz in 20 gallons of water. 

Yes, Permethrin can be mixed with Tekko Pro IGR.

Permethrin SFR 36.8% is not labeled for any type of biting gnat or biting midge (another name for sand gnats) and may not provide effective control. We would recommend choosing a product that is specifically labeled for gnats or midges such as Talstar P or Onslaught. Both of these products are labeled for biting gnats and midges and can be sprayed over the lawn. Flying insects are hard to control because they do not readily come into contact with the areas where you have sprayed the insecticide, so it important to spray areas where the tiny flies actually land or hang out.

Permethrin SFR 36.8% is not labeled for chiggers. 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.

According to the Permethrin SFR product label you will mix ¼ fl. oz. of concentrate to 1 pt. water and use 1-2 fl. oz. of dilution to spray on each animal. Spot treat back, face, legs tail and ears. If you would like to "dip" the dogs you will use ¼ fl. oz. to 1¼ gallons water and thoroughly wet the dog to the skin with sponge or rag. Let drip dry.

Per the product label: Use 4 to 8 ounces per 100 gallons of water or Broadcast 0.9 to 1.8 Fluid Ounces Per 10,000 sq. ft. This will be best applied by way of a tank sprayer and not by a hose end sprayer. If a hose end sprayer is the only available option it must be one with a dial to select the correct dilution rate per gallon/1000 sq/ft. You would set the dial to 1 teaspoon per gallon of water per 1000 sq/ft. 

Permethrin SFR 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.

Onslaught FastCap is a unique insecticide that has an encapsulated pyrethroid plus prallethrin for quick knockdown. Permethrin SFR contains permethrin - a different pyrethroid - and it is not encapsulated. The encapsulation really helps products to last longer in the heat and sunlight in desert environments better than the Permethrin SFR would. Our other most popular insecticides to rotate with Onslaught would be Cyzmic CS or CyKick CS. You could always add 0.25 - 0.5 oz of ExciteR insecticide to either Cyzmic or CyKick for that extra quick knockdown, if desired.
