UC Study Discovers Deadly Chemical in 34 Flea & Tick Pet Products

Dog sick from flea prevention treatment containing pesticides as shown on PawPurity's Blog

Flea and tick prevention pet products are commonly available over the counter, but a recent study found that many of these contain dangerous levels of the chemical TCVP. Researchers from the University of California analyzed 34 popular over-the-counter flea and tick preventatives and found that all of them contained levels of TCVP that could be potentially lethal to dogs. 

Flea and tick prevention pet products containing the chemical Tetrachlorvinphos, also known as TCVP, are being sold in stores across the country. But what many pet owners don't know is that TCVP is a dangerous pesticide that can cause serious health problems in animals. In fact, the EPA has classified TCVP as a "restricted-use" pesticide, which means certified applicators can only use it. The EPA has classified TCVP as a level 3 (high) toxicity for dogs and cats.

If you're using any type of flea or tick prevention product on your pet, read the label carefully to ensure it doesn't contain TCVP. It’s time to learn more about this deadly chemical that can be very harmful to your little four-legged babies. So keep on reading to learn more!

Beware of what's in your flea & tick prevention treatments

What is TCVP?

TCVP, or tetrachlorvinphos, is a broad-spectrum organophosphate insecticide that was once widely used in household pest control products. However, due to its high toxicity to mammals and birds, TCVP has been phased out of production in many countries. While it is still used in some parts of the world, TCVP should be avoided if possible.

What Makes TCVP Dangerous to Pets?

TCVP works by disrupting the nervous system of insects, causing them to become paralyzed and eventually die. However, this same mode of action also makes TCVP highly toxic to mammals. Studies have shown that exposure to high levels of TCVP can cause neurological damage in humans and is also lethal to dogs and cats. Ingestion of even small amounts of TCVP can cause pets to have vomiting, diarrhea, muscle tremors, and seizures. In severe cases, TCVP poisoning can lead to respiratory failure and death.

What to Do if Your Pet Has Been Exposed

This pesticide can be highly toxic to animals, and even small doses can cause serious health problems. If your pet is experiencing any symptoms, such as vomiting or seizures, it is important to bring them to the vet immediately. Your veterinarian will be able to provide you with specific instructions on how to care for your pet and what steps to take next. In some cases, exposure to TCVP can be fatal, so it is important to seek professional medical help as soon as possible.

There is no specific antidote for TCVP poisoning, but aggressive supportive care can be lifesaving. With prompt treatment, most pets recover from mild exposure with no lasting effects. However, severe or prolonged exposure can cause permanent neurological damage or death. To avoid risks to your pet's health, always choose pet-safe pest control products and store them securely out of reach of children.

How to Spot a Product That Contains TCVP

There are a few things you can look for when trying to spot a pet product that contains TCVP. 

  • First, check the ingredient list on the label. If TCVP is present, it will usually be listed as "tetrachlorvinphos" or "TCVP." You may also see it listed as "O, O-diethyl O-4-nitrophenyl phosphorothioate." 
  • Secondly, take a look at the safety data sheet (SDS) for the product. The SDS is required by law to list all of the ingredients in a product, including any hazardous ones. Therefore, if TCVP is present in the product, it will be listed under "Hazardous Ingredients." 
  • Look for the EPA registration number on the label. This number will tell you whether the product has been approved for use by the Environmental Protection Agency. If you can't find the registration number, or if it starts with "EPA Reg. No." then the product doesn't contain TCVP.
  • Finally, you can contact the manufacturer directly and ask if TCVP is present in their product. If they are unable or unwilling to answer your question, that's a red flag. They should be able to tell you whether their products contain TCVP. 

How to Find Safe Flea and Tick Prevention Products? 

With warm weather comes the increased risk of flea and tick infestations for our furry friends. Unfortunately, these pesky pests can not only make your pet uncomfortable, but they can also transmit dangerous diseases. The good news is, fleas are more prevalent in warmer weather. Ticks on the other hand are a year-round problem. Even during the coldest winter months, ticks may move around slower, but they’re still just waiting for the right moment to appear and latch onto your furbaby.

Fortunately, there are several effective fleas and tick prevention products on the market. However, it's important to be discriminate when selecting a product, as some contain harmful chemicals. Here are a few tips for finding safe and effective flea and tick prevention products for your pet:

  • Read the label carefully. Ensure you understand what active ingredients are in the product and what they do. Avoid products that contain harsh chemicals such as TCVP,  pyrethrins, and permethrins.
  • Choose a product appropriate for your pet's size, age, and health condition. For example, some products are unsafe for puppies or kittens, while others may not be suitable for older pets or those with health problems.
  • Check into 100% natural products, as most are made of plants and minerals, not chemicals or pesticides.

The Takeaway

The FDA has warned pet parents to stop using flea and tick prevention products containing the deadly TCVP chemical. If you have any of these products in your home, please discard them immediately. Many safe and effective options are available to protect your pets from fleas and ticks, so there is no need to take unnecessary risks with their health.
