Permethrin lasts for 40 days on the ground or plants and surfaces, providing long-lasting protection against pests. If sprayed on clothing, it lasts through 5 normal washes, making it a great option for outdoor enthusiasts.
Here's a breakdown of the types of insect repellents available:
- EPA-registered products that have been tested for efficacy and safety.
- Unregistered products that have been tested only for safety.
EPA-registered products are the way to go if you want to ensure you're using a product that's both effective and safe. Permethrin SFR is an EPA-registered product that begins working almost immediately upon contact, producing a rapid knockdown of pests like mosquitoes and flies.
Safety and Precautions
Wear protective clothing like gloves, long sleeves, and eye protection when handling Permethrin SFR 36.8% insecticide. This is crucial for safe handling.
Keep children and pets away from sprayed surfaces until they're fully dry. It's essential to prevent accidental exposure.
Proper ventilation is necessary in enclosed spaces when using Permethrin SFR. This will help prevent inhaling the insecticide.
Always follow the label directions for safe and effective pest control. This includes rinsing off Permethrin insecticide if skin or eye contact occurs.
Clothing treated with permethrin must be marketed with a pesticide use label, which should be followed carefully.
May Cause Side Effects

Dogs and cats that have permethrin on their skin may act strangely, flick their paws, twitch their skin or ears, or roll on the ground.
If you're using permethrin-treated clothing, only the skin surface covered with the factory-treated clothing is protected from pests.
Long-term exposure to permethrin can cause liver weight gain in dogs and mice, and skin irritation in rabbits.
Can I Wash Treated Clothes With Regular Clothes?
You should wash permethrin-treated clothes separately from your everyday clothes. This helps ensure the longevity of the treated clothing's insect-repellent properties.
Permethrin breaks down over time, but small amounts can still be left on clothing or deposited on other clothing, depending on the efficacy of your washing machine.

Environmental and Health Impact
Permethrin can stick to sediment in surface water for over a year, but it doesn't usually contaminate groundwater because it doesn't mix well with water.
If permethrin is applied to surfaces indoors, it can last for weeks, with 60% of the applied amount still present after 20 days of exposure to daylight.
Permethrin can also be absorbed by plants, with trace amounts found in edible parts of plants like sugar beets, wheat, lettuce, and cotton up to 120 days after planting.

Non-Cancer Effects of Long-Term Exposure
Long-term exposure to permethrin can have some concerning effects on our bodies. Researchers have found that dogs fed permethrin had more tremors than those that didn't eat it.
The liver is a vital organ that can be affected by long-term exposure to permethrin. Researchers fed dogs and mice permethrin for up to 2 years and found that their livers increased in weight.
Pregnant women who used permethrin to treat scabies or head lice during pregnancy didn't experience any adverse effects on their pregnancies. However, their offspring might be affected.
Rats fed permethrin when pregnant had offspring that weighed less, and some of their offspring developed extra ribs more often than control rats.
Fate in the Environment
Permethrin doesn't mix well with water, so if it gets into surface water like lakes or streams, it sticks strongly to sediment and can stay there for over a year.
Sunlight can break down permethrin on the soil surface and in water, but it doesn't evaporate easily when applied to surfaces. In an experiment, 60% of permethrin applied indoors near a window was still on the surface after 20 days.
Permethrin can stay on plant leaves for between 1 and 3 weeks. Scientists found trace amounts of permethrin residue in edible plant parts at 30 and 120 days after planting.
Foods like bananas, collard greens, squash, and watermelon have been found to contain trace amounts of permethrin, but less than 1% of over 1,700 food samples tested had detectable levels of the chemical.

You can also use it to treat preconstruction logs and lumber for new buildings and structures.
Mix 0.5 to 1 ounce of concentrate per gallon of water, depending on pest type and severity, and mix thoroughly before applying evenly to areas where pests gather.
Factory-Treated Clothing with Insect Repellents
Factory-treated clothing with insect repellents is a great option for outdoor enthusiasts and people who spend a lot of time in areas with high insect activity.

Permethrin is effective in repelling target pests, including mosquitoes and ticks, and it's been shown to be effective in controlling these pests in various studies.
However, it's essential to note that permethrin factory-treated clothing only protects the skin surface covered with the treated clothing, so it's still necessary to treat other exposed parts of the body with an insect repellent.
There are over 1400 registered products containing permethrin, which can be used in various forms, including liquids, powders, and sprays.
To get the most out of permethrin factory-treated clothing, it's best to combine it with additional insect-repellent products for enhanced protection.

Regulations and Registration
The Environmental Protection Agency (EPA) requires a registration or license from manufacturers before selling or distributing a pesticide, including permethrin, in the United States.
This registration process involves evaluating the health and environmental effects of each chemical and product, including studies on human health and environmental risks.
To ensure continued compliance with current scientific and safety standards, the EPA periodically reevaluates all registered pesticides, including permethrin.
The most recent comprehensive human health risk assessment for permethrin was completed in February 2006, and a revised assessment was conducted in April 2009.
Here are some key dates related to the registration and review of permethrin:
- February 2006: Completed comprehensive human health risk assessment
- April 2009: Revised assessment, including evaluation of factory-treated clothing exposure scenarios
- June 2011: Initiated new review of all permethrin uses, called registration review
- 2017: Expected completion of registration review of permethrin
