Permethrin SFR 36.8% - Questions & Answers

We recommend using 1 2/3 fl. oz of Permethrin SFR 36.8% per gallon of water for ant mounds.The label recommends that you treat each  by applying 1-2 gallons of emulsion to each mound area by sprinkling the mound until it is wet and treat a 4 foot diameter circle around the mound  so the ants do not move their mounds. Use the higher volume for mounds larger than 12". For best results, apply in cool weather, such as in early morning or late evening hours, but not in the heat of the day.

Permethrin SFR 36.8% is safe to be used if you have pets as long as it is used according to the label instructions. You have to keep everyone including pets and children out of the treated area until it has completely dried. 

Permethrin SFR would have limited results on cicada killer wasps as would any liquid application.    

Dusting the holes with something like Tempo 1% Dust will allow it to flow through the nest better than a liquid

Many of our customers have used Delta Gard Granules to help limit the number of cicada killers in their yard with some success. Still, the only surefire way to get rid of them is to treat the individual burrows.
Cicada Killer wasps thrive in disturbed environments, such as landscaped yards and places where bare soil is exposed. You can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over saturated lawns either, so over watering during their season will help prevent them. 

We also like to let our customers know that the Cicada Killer wasps are beneficial insects that provide free pest control for a couple months each year. Cicada killer wasps paralyze and provision their burrows with other insects to feed their young. The beneficial Cicada killer wasps, while large and intimidating to see, are mostly harmless and there have been very few reports of anyone getting stung by just being near them. In most cases where a sting was reported, the wasps were being held or molested in some way. Cicada Killer Wasp stings are also reported to be almost painless.

 

 

Permethrin SFR is not labeled to be mixed with paint so we cannot give a recommendation as to what strength.  We can not recommend using any product in a way that does not follow the instructions on the product label.

Hose end sprayers are all calibrated differently. For instance, the particular sprayer you have may be calibrated to spray 1 ounce of product per 1 gallon of water but another brand may be calibrated to spray 3 ounces of product per gallon of water. The problem with pre-filled hose end sprayers is that you have no way of knowing how it is calibrated. We recommend that you purchase a new hose end sprayer that is adjustable. We have a great model available on our website called the Chapin Liquid Hose End Sprayer Model 6005. Permethrin SFR is only labeled for mosquito control on livestock premises. A better product for mosquito control outdoors is Talstar P. Talstar P is gentle on vegetation where you will be spraying for mosquitoes and it will last up to one month for mosquito control. When using Talstar for mosquito control, you will use 1 oz of product per gallon of water.

Permethrin SFR is not labeled for general mosquito control so we do not recommend it for this use. 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. (Exciter is a pyrethrum which causes a faster kill but it is not an IGR).

Permethrin SFR is not labeled for that use. To treat spider mites, we recommend using Onslaught as a residual to cracks and crevices, floors, window frames, door frames. You can also use sterifab as an on contact kill to be applied to mattress, and furniture.

This product can absolutely be used on dogs for tick control. You can use it diluted with water as a dip, or a general rub down on their fur for control. Please see the bottom of page 16 of the Product Label for exact mixing rates and how to apply properly to your pet.

Perthmethrin SFR can be used around pools but care should be taken to make sure the product is not getting in the pool.

We do not recommend to apply Permthrin indoors at all or for bed bugs. We recommend using one of our Bed Bug kits. It really takes more than one product to eradicate bed bugs. This is why we have specially put our kits together.

Permethrin SFR 36.8% can be used as a cattle spray. The application raio varies, depending on what you are treating them for. Please find page 16 of the product label for application instructions.

Yes, we recommend that you mow your lawn 1-2 days prior to your first application of Permethrin and NyGuard IGR. You will wait two weeks and provide a second application. You can perform a third and/or fourth application if needed depending on the level of fleas (waiting two weeks in between treatments).

These products should not be mixed together. There is no valid reason to mix Onslaught  and  Permethrin SFR together.  They are both synthetic pyrethroids so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

 

Permethrin SFR 36.8% can be used indoors and is an oil based product. It could stain the baseboards and carpets. Please let us know if you have any additional questions.

Permethrin SFR NOT labeled for and should not be used in grazing pastures at all. If you do have a grazing plot/area that was treated with the product, then the grass should be allowed to grow high and then be cut several times before the animals/horses can be turned out to graze again.

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.

Permethrin SFR 36.8% is labeled for certain mites. You first want to ID the type of mite species. You can contact your Cooperative Extension Office for the ID. 

Yellow flies are a relatively new species so there is not anything labeled for it just yet and no research really as to what works for them.  Permethrin SFR may help to eliminate them as it labeled for mosquioes and flies but it is not labeled for mosquitoes around the yard. Something like Talstar P could be used and may offer some relief.  There is just not enough information available about this new pest.

Permethrin SFR 36.8% works best if applied in the morning or evening. When temps are lower. the effectiveness of the product can be compromised if applied during the heat of the day.

Permethrin SFR is not labeled for use on clothing and is not formulated for such a use. We do carry a permethrin-based product called JT Eaton KILLS Bedbugs, Ticks, and Mosquitoes that is labeled for use on clothing. It comes in a ready-to-use spray bottles and does not need to be diluted.
