Connect with a local pro todayWhat is Permethrin?
There are over 400 different compounds listed and registered in the United States that can be used as insecticides. Permethrin is one of the most popular of them.
Permethrin is a synthetic version of pyrethrum, a dry powder made from the crushed petals of the chrysanthemum flower, which is mainly grown in Kenya. Botanical versions of pyrethrum are called pyrethrins.
The Environmental Protection Agency (EPA) lists over 3,500 registered products that use pyrethrum (pyrethrins) or pyrethroids as the active ingredient. Along with permethrin are other related insecticides. Below is a partial list.
- Allethrins
- Bifenthrin
- Cyfluthrin and beta-cyfluthrin
- Cypermethrin
- Deltamethrin
- Lambda-cyhalothrin
Along with permethrin, these active ingredients, in various formulations, constitute the bulk of the insecticides used in the 3,500 products listed by the EPA.

How Does Permethrin Work?
Permethrin attacks the central nervous system of insects, specifically, the sodium channels. This interferes with the functions of the neurons and causes muscle spasms, leading to paralysis and death.
It can enter the body through dermal contact with exposed skin or ingesting it by eating it. It also acts as a repellent.
Repellents interfere with an insect’s senses, including taste and smell. Their eyesight is so poor that cutting off their other senses effectively renders them blind. Then they tend to avoid areas where they can’t see, smell, or taste the world around them.Our #1 Ranked For: Termites,Bed Bugs, and Larger Infestations

Are Permethrin Sprays Effective?
Yes. Permethrin has a long track record of success in the United States and around the world. It’s what is called a broad-spectrum insecticide, meaning it kills many different insects.
How To Use A Permethrin Spray
Hold the spray nozzle at least six to 18 inches away from the surface or fabric you’re spraying. Use a smooth motion back and forth across the surface until it is damp to the touch, but not dripping wet.

Are Permethrin Sprays Safe Around My Pets And Children?
It depends on how old your children are.
Small children, and most pets, are physically smaller than adults. This means they have a greater skin surface to weight ratio. Insecticides can penetrate human skin, so the more skin per body weight, the greater the amount of pesticide that enters their body relative to their weight.
Infants and small children have higher respiratory rates than adults, resulting in them breathing in more insecticidal fumes than adults. Additionally, children eat and drink more relative to their body weight than adults.
Finally, infants and young children spend much of their time crawling around on the floor, which is where you’re most likely to spray with permethrin insecticides. The same thing goes for pets.
Warning
This product is not safe for pets and young children, as they are more susceptible to the toxic effects of pesticides.
Infants, small children, and pets are more susceptible to toxic effects from pesticides than adults so they should be kept out of treated areas for several hours after spraying.
The CDC recommends a variety of active ingredients as a mosquito repellent and/or tick repellent to protect you and your family from the Zika virus, rocky mountain spotted fever, Lyme disease, and scabies, among other diseases.
