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.
According to the Permethrin SFR 36.8% product label, you may spray 4 fl oz to 10 gallons of water. For severe infestation, it is permissible to use 4 fl oz to 4 gallons.
When treating poultry directly: Use 1-4 fl oz in 3 3/4 gallons water, which should treat roughly 375 birds. Use 1 gallon of coarse spray per 100 birds.

The Permethrin SFR 36.8% Insecticide Product Label states under the PPE section:
All other mixers, loaders, applicators, and other handlers must wear:
- Long-sleeve shirt and pants,
- Shoes plus socks, and
- Chemical-resistant gloves for all handlers except for applicators using motorized ground equipment,
- Chemical-resistant apron for mixers/loaders, persons cleaning equipment, and person exposed to the concentrate and for handlers performing animal dip applications.
In general you should try to keep the animal from excessively licking or biting at themselves after an application. If you can set aside a little time after the application to be in the animals area and keeping an eye on them while they dry out and the product absorbs, that would be ideal. There isn't a way to completely keep an animal from gaining access to some on their bodies, and to an extent this has been taken into account for by the manufacturer in these types of applications. If you have any concerns about your specific animals health or safety when using the product on them, we'd recommend contacting the manufacturer directly or discussing the treatment with your vet prior to use and application.
Yes, Permethrin SFR is labeled to control yellow jackets / hornets. We also have a guide here that can help.
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.
