Permethrin SFR 36.8% - Questions & Answers

Permethrin SFR will kill stink bugs but there are other products such as Cyper WP which lasts a bit longer and stays on the surface of porous areas making it more available to this pest. Unfortunately if you are dealing with them in your house right now you will only see limited results. Stink bugs move into structures to overwinter. They usually squeeze into wall voids, false ceilings, attics and other areas that are inaccessible to people and insecticides. As the heat kicks on in the house, the stink bugs warm up and start becoming active and emerge from hiding, driving homeowners nuts. Because most folks usually have no idea where the bugs are harboring you can only treat around baseboards, door frames and window frames and hope the insects will emerge where you have sprayed. After they contact the treated areas it can take several hours for them to die. It is still worth spraying now to get rid of some of the bugs, but you will keep seeing them until late spring when they will emerge en masse and leave your home. They do not eat, mate or lay eggs while indoors so need to worry about any damage or future baby stink bugs. This year you can be proactive by stopping these pests before they move in for the winter. You should spray Cyper WP outdoors around your door frames, window frames, vents, eaves, around the bottom of your foundation, and any other crack or crevice where an insect could gain entry once a month August-November. Most folks see a 80-90% reduction in stink bugs the first year and even better results in the following years as the stinkbug pheromone fades away.

Permethrin SFR 36.8% will not harm cats after the treated area has dried. This may take 2-3 hours.

Permethrin SFR is labeled for army worms and will kill just about any insect.  We do not see how Permethrin SFR could be harmful to Geese.  It is only strong enough to kill small insects.  If it is safe for use around children and pets, we are confident that it would be safe for geese and water foul.

You should use the higher usage rate of Permethrin SFR for heavy infestations, faster knockdowns and longer lasting residuals and lower usage rates for maintenance sprays. You will need to use higher volumes of water to get the product over thick, dense vegetation. If you are treating your lawn for ticks, we recommend you use the higher specified usage rate of 0.8 fl oz for 1,000 sq ft using whatever volume of water is needed. If you are treating up close to your home you are permitted to use the .5% emulsion (1 2/3 fl. oz. per gallon of water) per 1,000 sq ft as a perimeter treatment. 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.

Permethrin SFR is a great choice for Japanese Beetle control. Be sure to use it at the highest concentration, avoiding the blooms if possible (may cause browing). Permethrin SFR may need to be applied once per month to avoid Japanese beetle damage. Pets and children need to be out of the area while the application is being done and they may return as soon as the application is dry. The Permethrin SFR product label and MSDS are available on our site for further product information.

In this case you can use the Permethrin SFR 36.8% at the .5% to the 1.0% based on the label with is (.5%) 1 2/3 oz  - (1.0%) 3 1/3 oz per gallon of water. This usage ratio would keep you within the 1% mixture rate. This would be enough for fleas and other pests outdoors depending on the weather condition (amount of rain, UV rays, etc). You do want to be sure the pets are completely out of the area while you are spraying, and until the product dries.

You can use PErmethrin SFR in a hose end sprayer as long as it can be calibrated to the required usage rate. According to the Permethrin SFR product label:  For fleas, ant and ticks in lawns - Mix 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. 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, Permethrin SFR is labeled for termites. It is recommended that you use this product around the perimeter of your home outdoors in a trench. The termites will come in contact with the treated soil and get it on themselves, but they will not take it back to the colony.

A better option would be to use Premise Foam in the areas where you have seen activity. This will be injected at the studs of the wall. 

Yes, Permethrin SFR 36.8% is a non-selective insecticide, so it would kill roaches of any species or size that come into contact with the direct spray or residual. If you are only seeing roaches occasionally and need a residual spray to create a barrier, then you have many options. Temprid SC is water-based and contains two active ingredients for longer control. It also does not have the odor that sprays with permethrin will have. If you are seeing different life stages and/or seeing roaches consistently, then we would recommend our Roach Control Kit Rotation A. Please see our Roach Treament Guide for more information and tips.

The shelf life for Permethrin SFR 36.8% is 3-5 years from the date of purchase if stored at room temperature.  You shoudl only mix up what you are going to use the day you plan to make an application.  Any mixed solution left in a sprayer will become ineffective.  Always follow the product label for mixing and application rates for the pest(s) you are treating.  Not following these guidelines can adversely affect the product and your results. 

Permethrin SFR is a different formulation than the products that are labeled for use on clothing and it should not be used to treat clothing under any circumstances. Permethrin SFR is not labeled for chiggers which is why we do not recommend it for chiggers. Manufacturers do a lot of research and testing before they are allowed to add an insect to their label. In this case the manufacturer may have felt that the product was not effective enough on chiggers to add the insect to the label or that chiggers were not a significant enough of a pest to do the research and testing on so didn't even try to add it to the label. SFR stands for Surfactant for Richard. Apparently Richard was one of the staff members who helped formulate the product and the suffix stuck.

After all surfaces treated with Permethrin SFR 36.8% are completely dry, the dogs can return.

According to the Permethrin SFR product label you will need to use about 1 2/3 fl oz per gallon of water for each 1,000 sq ft area. You will need to keep your dog out of the area during the application and the dog can return to the area after it has dried.

While the Permethrin SFR is a great product it is not what we would recommend for a roach spray. If you have a current infestation of roaches, we recommend the products that come in our Roach Control Kit Rotation A. The products in the Roach Control Kit Rotation A are perfect for roach control problems in homes. This professional kit includes Temprid SC Insecticide for spraying the outside perimeter of the home and inside underneath appliances like fridge and stove, behind cabinets, under toilets and sinks, etc.  It also includes Maxforce FC Magnum roach bait gel which can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Gentrol Point Source stations provide an IGR (Insect Growth Regulator) that will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. Finally, the kit includes Catchmaster 100i Insect Monitor glue boards to help monitor your infestation and treatment.
