Does Permethrin Kill Ticks on Contact (Dogs & Horses)?

Permethrin is a chemical used in many products for treating ticks. There are, however, many misconceptions about how it works and what it can do. This article will address some of the most common questions about permethrin and its efficacy against ticks.

What does permethrin treat? Permethrin is often used to kill or repel parasitic bugs on humans and animals which can lead to diseases like Lyme disease.

It’s also found in clothing that is treated with the chemical before being worn by consumers as well as bedding materials that have been sprayed with an insecticide containing permethrin before they are sold.

The article will teach you about permethrin, what it is and how it works. It will also tell you the safety precautions to take care of your skin before using this product.

The article will then show you where to buy permethrin so that you can purchase your own protection against ticks.

Does Permethrin Kill Ticks?

Can Permethrin kill ticks? Yes, permethrin is a pyrethroid insecticide that can be used to kill ticks. However, it does not work on all species of tick and needs to be applied directly to the tick or in an area where they are living.

The active ingredient, permethrin, kills ticks by disrupting their nervous system causing paralysis and death. Ticks die within two to four hours after contact with permethrin.

Permethrin is effective against deer ticks (Ixodes scapularis), American dog ticks (Dermacentor variabilis), brown dog ticks (Rhipicephalus sanguineus) and lone star ticks (Amblyomma americanum). It has been shown to provide up to eight weeks of protection from the ticks.

How long does it take permethrin to kill a tick? It will take around 2 to 4 hours for permethrin to kill ticks on horses, dogs, cats, cattle and other livestock after contact.

However, the whole infestation may be eradicated within 36 hours after application because the contact happens over time. It will have no effect on humans unless they are covered in permethrin grease.

What percentage of permethrin kills ticks? Effective tick removal can be achieved with a single topical application of permethrin at the estimated 25% concentration level.

In ticks, “concentration-dependent toxicity” was observed in which less than 10% of the applied dose resulted in death after 24 hours.

The lethal effect appeared to be induced by contact to an insecticide coating applied on a small amount of cotton that sticks to its cuticle or may have been absorbed through invasive penetration.

At approximately 5% concentration, permethrin did not cause significant mortality within 30 days following a single application, even though mosquito mortality rates were still high.

This suggests that contact to the pesticide formulation coating caused or enhanced larval mortality at very low concentrations and acted synergistically with other insecticides.

Permethrin Spray for Ticks

Permethrin is a synthetic pyrethroid commonly used as a spray to kill ticks, mosquitoes, and other insects. It kills ticks and their larvae by interfering with the nervous system.

There are several permethrin brands available in a topically sprayed form that may be more effective than aerosolized spray methods.

When it comes to effectiveness, Anvil from Zoetis has been among the best-reviewed products online at this time.

Sergeant’s Pet Care Products’ Non-Flammable Permethrin Insecticide was also rated highly by users for its availability in stores and lower cost over other brands online.

Efficacy: With these high ratings in mind, there is evidence that permethrin is one of the best killers of Ticks.

Permethrin spray for ticks generally is not carcinogenic because it does not bind to skin fats so they can’t accumulate in concentrations high enough to generate risks of cancer tumors in animals.

FAQs for Permethrin for Ticks

Permethrin for ticks on humans

Permethrin will not kill those ticks that have already joined onto humans, so the best course of action is to treat clothes and skin with permethrin just before going outside for an extended period of time in tall grass or brush.

Permethrin should also be used along and around the edges of gardens or dug-up areas where these pests commonly reside.

The best way to diagnose a tick-borne illness is by having your doctor take a blood sample and then using it to test for particular antibodies against certain pathogens.

If you experience symptoms such as fever fatigue, muscle pain, rash, or joint aches please consult your health care provider about testing for tick-borne diseases.

Permethrin for ticks in the yard

I would recommend that you speak with your neighbor to discuss the possibility of forming an agreement. When it comes to chemicals, what is okay for one person may not be okay for another.

There are risks involved when using chemical insecticides in yards but if you want a permanent option, applying permethrin at the height of tick season is most likely your best bet.

If done properly with clothes or gloves, there shouldn’t be any risk of getting permethrin on oneself. I don’t know about any long-term effects so it would be best to consult an expert in the field such as a doctor for this question.

My recommendation is to make sure both parties agree before doing anything and consult each other’s kids about what they know about the dangers of the permethrin.

Permethrin for ticks on dogs

The first thing to do is identify the type of tick. Permethrin is only effective against deer ticks, so if your dog has an issue with black-legged ticks it will not help.

If you have confirmed that Deer Ticks are the problem then go ahead and apply permethrin according to instructions for dogs or humans on the bottle label, but only every three weeks because permethrin must be reapplied after 48 hours if wet.

And please take your dog in for testing to collect samples for Borrelia testing because there are other tick-borne diseases out there like Lyme Disease.

There are also topical products sold specifically as repellents, like Preventic Collar (alcohol free), which work by creating a physical barrier between the ticks and the dogs.
