Permethrin SFR 36.8% is a broad spectrum insecticide for surface pests like ants, spiders, flies etc. It will not treat subsurface pests like grubs or repel animals like raccoons. It is likely too late to put down any grub control products in northern areas: you want to wait until next year before egg hatch.
We sell a variety of Raccoon Live Traps that you can browse here.
While we do sell animal repellents, most of these will not be labeled for control of raccoons. This is because raccoons are scavengers, so smells may attract them more thinking there is a food source nearby. In general, repellents are also behavior modifiers, so their efficacy can vary.
No, Permethrin SFR 36.8% cannot be used on any type of edibles. You may try using a product such as Fertilome Triple Action instead. Please be sure to review the product label for more information and complete application instructions before use.
When using Permethrin SFR 36.8% for fleas and ticks in the lawn, be sure to add Archer IGR to impede the insects reproductive cycle. The products should be applied once every two weeks.

No, Permethrin SFR 36.8% is not safe to use on cats. In general, cats can be very sensitive to products containing the active ingredient permethrin, so you should refrain from using permethrin products around cats unless the product is expressly labeled for that application. You can browse flea and tick products for cats here.
We would recommend using the combination of Permethrin SFR 36.8% and Pivot 10 IGR for active flea infestations both indoors and outdoors. These 2 products can be tank mixed in the same tank sparyer and applied in 1 application.
Demon WP would not be tank mixed with Permethrin SFR. Demon WP and Pivot 10 IGR can also be tank mixed together however indoors, applications should be along the cracks and crevices around the interior. Demon WP cannot be broadcasted over carpet areas. It also will leave a white powdery residue behind once the liquid application has dried.

Permethrin SFR can be used in a mist blower when used as directed on the product label, but it is not labeled for mosquito control.

Permethrin SFR 36.8% can kill roaches but it is not a top choice for active roaches indoors. If treating for an active roach infestation, we would recommend using one of our Roach Control Kits that contain the most effective combination of products and enough product for repeat applications that are required every 14 days.
Please view those Roach Control Kits and our Roach Treatment Guide for more information on the most effective treatment program.
Per the product label, the addition of a surfactant with Permethrin SFR 36.8% will certainly help with penetration during the application and help it stick better to trunks, branches, limbs, foliage, etc.
A non ionic surfactant (wetting agent) such as Hi-Yield Spreader Sticker would be recommended at the rate of 2 - 4 tsp. per gallon of water.
For indoor applications, you can use 1 2/3 oz of Permethrin SFR 36.8% per gallon of water. Please review the product label for complete application instructions.

With Permethrin SFR 36.8% for sod webworms, you will 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. You want to make sure you are using enough water to get it down to where they are better so 1 gallon is usually not enough.
Permethrin SFR 36.8% is labeled to be applied to goats as directed on the product label.
When using a product like Permethrin SFR, the hornets would have to directly contact the treated areas to be affected. We recommend using a product such as Delta Dust Insecticide to apply directly to the bored holes, and this product can be reapplied every 2 weeks as necessary. You can use a Bellow Hand Duster to make the application. This way, the hornets will fly through the dust picking it up and carrying it on their bodies back to the nest. Please be sure to review the product label for more information and complete instructions.
