A class action lawsuit alleges that Wondercide Flea & Tick Control spray is not all natural, as its marketing claims, and really contains at least two synthetic and possibly harmful ingredients.

The Wondercide class action lawsuit was filed by Chanan Nathan Pasik against Boon Technolgoies LLC, the makers of Wondercide.

Pasik says that he purchased Wondercide Flea & Tick Control on Amazon to help protect his dog from fleas and ticks.

The class action lawsuit state that Wondercide is a product that can be used to repel fleas and ticks from pets, and can be used to eliminate such pests from the home.

Pasik says he saw advertisements that Wondercide is safe, 100 percent naturally derived, and free from synthetic pesticides, and decided purchased the product at least in part because he believed this to be true.

The Wondercide class action lawsuit claims that these representations are false, and asserts that Wondercide contains two synthetic chemical substances, contrary to the product’s advertisement.

Allegedly, the one of the synthetic ingredients that the product contains is Sodium Lauryl Sulfate (SLS), a surfactant or cleaning ingredient that is created industrially and does not occur naturally. This chemical reportedly repels fleas and ticks.

According to Pasik, SLS is linked to skin irritation, allergic reactions, dermatitis, and dryness. Pasik calls the substance a “toxic chemical.”

The class action also claims that the makers of Wondercide do not acknowledge that SLS is a synthetic chemical, and instead defines SLS as “coconut oil” in its glossary. Allegedly, the makers say that Cedar Oil is the only active ingredient in Wondercide.

The Wondercide class action lawsuit argues that “concealing a synthetic ingredient and defining such chemical as ‘coconut oil,’ while highlighting a natural ingredient in an alleged ‘100 Naturally Derived’ product” is deceptive, under the New York Business Code.

Pasik claims that Wondercide also contains Ethyl Lactate, a substance formed from lactic acid and ethanol, commonly used as a solvent. Allegedly, more synthetic substances may be discovered in Wondercide.

The Wondercide class action states that Pasik was financially injured because had he known that the product was falsely advertised and contained synthetic ingredients, he would not have purchased it or would not have paid as much for it.

Allegedly, many other consumers were similarly misled and financially injured by Boon Technology’s misrepresentations about their product.

The flea and tick repellant class action lawsuit asserts that Boon Technologies knew that consumers have a preference for natural products that contain no synthetic ingredients, and advertised their product as such in an effort to entice them to buy it.

Allegedly, the company knew or should have known that Wondercide did not contain only natural ingredients but misrepresented it none the less.

Boon Technologies reportedly reinforces its claim that Wondercide is all natural by pairing this message with images of people using the product around babies and pets.

Pasik is represented by Mark Schlachet.

The Wondercide Flea and Tick Repellant False Advertising Class Action Lawsuit is Chanan Nathan Pasik v. Boon Technologies LLC, et al., Case No. 1:19-cv-02357-FB-JO, in the U.S. District Court for the Eastern District of New York.

UPDATE: On April 2, 2020, the Wondercide class action lawsuit that challenged the company’s marketing that the pet product was 100% naturally derived was voluntarily dismissed with prejudice. That means that this particular Wondercide class action has completely ended and cannot be brought back to court.

The Wondercide class action lawsuit filed by Pasik claimed that the flea and tick repellant contains sodium lauryl sulfate which is a synthetic ingredient used mainly as a surfactant.

In addition, the Wondercide product also reported contained ethyl lactate which is considered a solvent.

According to the plaintiff, there could be even more synthetic ingredients included in the reported 100% natural flea and tick repellent product.

The Wondercide class action lawsuit claimed that consumers were misled by the “natural” marketing of the pet product and wouldn’t have purchased it if they had known the truth of the presence of synthetic ingredients.

Consumers preference for natural products has been increasing year after year, and studies show they are willing to pay more for products that are considered “natural” or “all natural.”

This preference includes food, cleaning products, beauty and skincare products, along with pet care products. Those who pay a premium for a product only to find out later that it contains synthetic ingredients may feel tricked by advertisements and seek legal action.

  1. SYLVIA COLLINS says:

    Please add me. I use Wondercide on pups sparingly and still have had concerns all along. This all is really scary.

  2. Iduma Best says:

    For the persons above claiming that this product killed your pets, are you saying definitively that this product killed your pets, was a necropsy performed? My mother took her Wallaby and a few dogs to Purdue University College of Veterinarian Medicine years ago under unrelated circumstances, they are excellent. If you are not positive, wouldn’t you be committing libel?

  3. Margaret Coleman says:

    I read these reviews so I will not buy this product after seeing it on Shark Tank no matter how good it sounded. I won’t risk the lives of my cats.

  4. julie says:

    come on why would you think it is safe for pets when it had “cide” in its name. Cide meaning killer. This was the tip for me that it would not be safe for pets. If it has the potential to kill anything it could be harmful to pets. You should try home remedies like apple cider vinegar or lemon and water for tick and flea control.

    There are many things that are “all natural” that can be problematic for pets.

    1. Iduma Best says:

      If apple cider vinegar & lemon have the potential to kill fleas, wouldn’t that be the same thing?

  5. Kim says:

    How can they claim & sell a product that isnt safe? Is there no regulation? None of their ingredient lists show “sodium laurel sulfate” or “ethyl lactate”. How can they “hide” it? I have also heard that essential oils are not safe for pets so how can these products be safe? I was looking for a safe alternative due to my pets elevated liver enzymes and enlarged liver which I believe is due to toxic flea & tick treatments so how can I be sure Wondercide is safe? That’s why I bought it! Discouraged by these comments

    1. Kathy Epperson says:

      Ask Merck, Pfizer, Elanco and many other big oharma companies how they get products killing thousands of dogs pass FDA approval?

  6. Ken Post says:

    I’m glad I found this article before placing an order from Amazon. According to one of the reviews the fine print on the bottle says it may cause neurological damage. That prompted me to search the internet. I’ll go with natural options to treat our yard.

    1. Tina says:

      I wish I’d have found this b4 I finally bought a bottle & sprayed it on my dog!🫢🥲. Please let me know when you find a SAFE product. I’ll keep looking.(& throw this bottle away!)

  7. Joni S says:

    Darn that’s maddening .. I used this in my little 10 lb pup all last summer and just bought a new bottle.. add me please

  8. Doreen says:

    Spray this along my foundation, on my lawn and shrubbery along with food grade diatomaceous earth about once a month from spring to fall. I use the flea and tick bottle spray on my deck and deck furniture. I have sprayed it on my hands and then on my dogs. Hopefully, it was not harmful.

    Lisa, We are devastated because needing to use safe products around a family member with HIT and MCAS. We used this product on our pet and around our home. We had rescued a beautiful beloved kitten and within a couple months she had what the vet called cancer. A massive growth in her chest that cut off her esophagus and she also could not breath. All her lymph nodes were swollen as well. She died. She was only a little over a year old. She had all her shots, was tested for leukemia and other feline diseases and came up negative. So we went ahead and paid the money to have her spayed. She was our baby. Spoiled to the max. She was smart, funny, well mannered and loving. We cannot stop crying. Our dog of 14 years had just had to be put down from old age days apart from her death. But her unexpected demise has really hurt our hearts. We thought she was a God-Send at this time with Covid and all the craziness going on. She was a much needed delight, companion and distraction from depressing events. We had named her “Sparkles” because that’s what she was. A shining star in the night. We have not stopped crying. She truly suffered. It has robbed of of our joy and peace. I was shocked to see your report of similar symptoms. The x-rays stumped our first two vets. Who gave her x-rays and took aspirations with no anesthesia because they thought she may not survive it. They gave her antibiotics and steroids hoping to reverse her condition to no avail. After about a month of suffering they referred us to an emergency hospital an hour away. After examining her they told us it was Cancer. She was now only barely alive and fighting with everything she had to stay alive. We spent the last 45 minutes with her reassuring her and telling her not to be afraid and that she would go to heaven and be ok. But we have not been ok since.
    Btw we saw these 2 women who created this product recently on Shark Tank getting a boat load of support and money to expand their business. Also using the so called natural products claim to lure the sharks into investing in them and their product.
    There is no way to bring our beloved pets back but I hope others will read this and be warned before using it on their own one and only beloved pets. Sincerely, Vicki jo

      I had to search out this article, checking again on it’s safety b4 buying another bottle. But, if you post you thots on Facebook on (Wondercide’s page) a lot of people will see it!!!😉

    I was just about to place an order and already have a smaller bottle of the f&t spray which I am not and have not used ON my pup. I am now increasingly concerned however I think people need to realize that as with any food or product one could have a reaction…to a particular scent, oil, food item…and the reactions happen to both canine, human, and feline. I have a particularly challenging situation as exterminators have turned me down (at least the reputable ones) because the house MUST be cleared (speaking of how toxic something is!) for 2-4 hours after treatment and we have an ill family member in a hospital bed that cannot be moved. But I was also going to get their shampoo bar in honey/oatmeal. And the outdoor spray as well. Now I am concerned. I am also going to get some more flea traps for more rooms. Glad that we are up to fall and winter I hope will help, but the reality is if the fleas have found a good home on my pup, I hope we can erradicate them with all the other advice I’ve pieced together including frequent vacuuming…
