flea and tick prevention

The temperature is finally climbing and springtime is finally blooming, and that means our dogs are eager to get outside. You want to make sure that no “hop ons” follow back inside your home, so it’s time to think about safe, effective flea and tick prevention …

… but the most common commercial flea products have been shown to be highly toxic, and so maybe you’re looking for a natural, chemical-free alternative.

A new type of product, a bandana containing permethrin for dogs, has been advertised as safe and harmless, but dog owners need to be careful before hitting that “submit order” button.

Commercial Flea and Tick Prevention

The dangers of oral insecticides (flea pills), pesticides, topical flea treatments and flea collars are no secret. These products can cause serious adverse health reactions in dogs and humans, and the Center for Public Integrity found over 25,000 reports of pesticide reactions have been reported to the EPA in the last 5 years (including 1600 canine deaths).

Here are just a few of the most common reactions to commercial flea products and permethrin for dogs:

  • Contact dermatitis (red, itchy, irritated skin)
  • Hyper-excitability
  • Muscle tremors
  • Uncoordinated muscle movements
  • Labored breathing
  • Excessive drooling
  • Fatigue
  • Fever
  • Vomiting
  • Diarrhea
  • Seizures

Because of this, many dog owners are choosing to make a switch to natural flea and tick protection.

What’s important to be aware of is that many pet product companies, producers and individuals are trying to market insecticide treatment as “natural,” safe and pet-friendly to appeal to the consumer.

“Insect Shield” Bandanas: A Chemical-Free Option?

Insect shield, insect-repelling, flea bandanas are flooding the market right now. These are advertised as friendly, safe, natural and/or non-invasive flea protection methods. Oh, cute! An adorable little add-on that’s fashionable, effective and safe for my pet, right? Finally, a minimally-invasive solution to flea control …

Not exactly.

These products can fool consumers. It’s important to look at what makes these products “flea repellant.” These are not natural, safe remedies, but are instead full of synthetic insecticides. One of the worst is permethrin.

Is it safe to use pyrethrin on dogs? Despite that natural claim, not at all.

Flea bandanas are supposed to be a useful tool to combat fleas, ticks, and mosquitoes in outdoor environments. But before you buy flea-repellant bandana, be sure to take a look at the ingredients that make it flea-repellant. Most commercial ones use insecticides, such as permethrin for dogs, in the fabric. Check the labels and product details thoroughly before buying.

Permethrin For Dogs: Read The Ingredient Label

Flea bandanas (such as those found on Petedge.com, Amazon, and Guardian Gear Insect shield) work by embedding permethrin into the fabric. Manufacturers spray this insecticide into or on the fabric. They say these products are good for 10-30 washings.

permethrin for dogsPermethrin is a type of pyrethroid, which is a synthetic compound used in insecticides. Permethrin is found in pesticide products like Nix, Advantix, flea shampoos and DEET. It is used as a widespread insecticide in agriculture, gardening, and commercial household insecticides.

Manufacturers will tell you that it’s a synthetic compound derived from Chrysanthemums – so you think, “natural and safe,” right? Despite this organic derivative, permethrin is a central nervous system poison – a neurotoxin. It was designed to be more toxic than the Chrysanthemum flower, penetrating insect shells and paralyzing their nervous systems. In mammals, it also poisons the liver and paralyzes the muscular system.

Along with a neurotoxin, it acts an endocrine system disruptor: poisoning the thyroid, parathyroid, pancreas and reproductive system. It can also cause liver damage, gastrointestinal poisoning and neurotoxicity with exposure or accidental ingestion. Symptoms of permethrin dog toxicity include:

  • Incontinence
  • Tremors
  • Paralysis
  • Difficulty breathing
  • Nerve damage
  • Muscular paralysis or damage
  • Coma

Death is also a side effect.

The EPA has a “toxicity class” rating for commonly used pesticides, where Level 1 = most toxic and Level 4 = least toxic. Permethrin toxicity is rated level 2-3, depending on the product.

Permethrin-containing products also carry the word WARNING or CAUTION on their labels. Flea bandanas should be given the same scope of caution. The EPA even says that these are toxic to the nervous system of people and pets, can trigger allergic reactions and are classified as “possible carcinogens.”

Risky Accessories

Permethrin is only found in dog-specific flea treatments since it’s highly toxic to cats and fish. It is also usually only found in topical treatments, since oral ingestion can lead to liver failure and neurological damage. If your dog accidentally chews his bandana, if you put it on your cat, if the cat finds the bandana on the floor, or if your dog goes swimming in a natural body of water – these are all putting your dog and several other creatures at risk for severe damage and death.

permethrin for dogsEven worse, the pyrethroids found in flea bandana products are also highly toxic to bees, birds and aquatic wildlife. The EPA even claimed that “flea resistance is an issue for effectiveness” – meaning that despite all of the toxicity, it might not even actually repel fleas in the first place. These cute bandana products appear harmless, but are dangerous to the health of you, your pet, and the environment. 

What If I Bought A Flea Bandana?

The best way to reduce exposure to permethrin is to avoid topical flea medications, DEET, flea collars and flea bandanas.

But what if you already bought one?

If you purchased a permethrin-based flea bandana for your dog, stop using it right away. And watch for the warning signs that your dog may be sick.

Signs of toxicity include:

  • Contact dermatitis (on-site itching, hives, or redness)
  • Swelling
  • Asthma-like breathing problems
  • Sneezing
  • Nausea
  • Loss of coordination
  • Convulsions
  • Vomiting

In people, this can also cause contact dermatitis, rashes, irritation, and endocrine system disruption.

The best flea and tick prevention shouldn’t harm your dog. So, toss the bandana and go with a natural alternative – homemade flea and tick prevention.
