Hartz Flea Collar Caused Fleas??


My name is Marlena and I have a two year old Russian Blue named Charlotte. I got her just over five months ago. About three months after I got her my mother got her a Hartz flea collar. She was doing great before I put the flea collar on her then about a couple of weeks ago I noticed that she started licking herself more than usual. After about a week of licking she started biting herself more than usual. Then about a week ago she started scratching way more than usual. I though that it was just because that’s what cats do, beings as though she’s my first cat. So when she would lay with me I would rub her head and neck and I noticed that she has scabs all over. What I did first was remove them but then I was told not to because I could irritate her more. So I sprayed her with Hydrocortisone Spray and stopped picking them. Now when I go back to rub her, I noticed they are getting worse. I don’t know what I should do, I don’t have the money for the vet or the expensive flea control medications. I only have enough money to buy the Hartz Ultra Guard Pro Flea and Tick Control. But I have read so many reviews and don’t wan’ to use it or would it be safe? I need help on what I should do so please help.


My puppy is about 10 months old and I bought the flea and tick ultra medication to prevent fleas from getting on him. We recently moved into a house that had a previous dog that had fleas so I just wanted to make sure that my puppy didn’t get fleas from this. So when I put the medication on him. It was fine. But when I got back from work he was starting to scratch a lot. I figured it was because he knew i put medication on his and he was just being fussy. Woke up around 3 am to find him scratching himself to death and biting his lower back to the point where it was a fresh wound and all the hair was gone off of it. This is when I knew I needed to take him to the vet. I went to the vet and realized that the trail I made when applying the medicine had made all of his hair fall off. He was shedding like crazy and had a huge strip of baldness on his back where I put the medicine on. When I went to the vet they told me he had gotten sick from the medicine I put on him and had to give him a shot to calm the burning that he was feeling all over his body. He is doing fine now, Thank the Lord. I wish I would have researched more about flea medication but when I realized that other people are going through the same thing I knew that it wasn’t just my dog who had a problem with this medication. He is in the process of healing and his hair is growing back slowly. His scabs from the biting are huge but are getting better too.
This medication might have killed my dog if I didn’t wash it off of him as soon as I did. I will always tell people never to use this product because of all the lives it has killed or made horrible because of it.

Flea and Tick Collar DOES NOT WORK!!!

Save your money!  I bought a flea and tick collar for my 5 year old boston terrier when he went to visit my in-laws.  I picked him up last night, after 3 days there (and 4 days WITH the collar on) to my surprise HE HAS FLEAS!  I have now spent $110 to treat him with Frontline, flea bath, and to have my house bombed.  I called the Hartz customer service nunber (1-800-275-1414) and spoke with a rude man who hung up on me when I started to tell him how I was going to complain about them to the BBB and report how terrible their product worked.  I immediately called back and spoke to a woman who was equally as rude and very sarcastically told me “Thanks for reporting this incident and your kind coments, you have a GREAT day”

I am beyond frustrated with this product.  After speaking to my Vet, they explained to me that the flea collar NEVER work anyway.  So, learn

10 months old

I wish I would have done more research. My kitty is 10 months old. I run a small animal recue from my home. So when I noticed a flea I flipped and got the flea drops. I applyed them to my 2 dogs and the my cat. I applied a cat formula to my kitty. within an hour she started to have seizures. After the 1st seizure I was able to wash the stuff off. I had to feed her water from a straw. She COULDN’T walk. She COULDN’T drink. SHE WAS BLIND!!!! She is still alive 18 hours later she is starting to walk again. I stayed up all night with her. When she meow’d I cried. Just as I had done when her mother gave birth to her and I heard her Meow for the 1st time. She is eating and drinking now. me and my vet are hopeul that she’ll pull thur…..She may never be the same she suffered Neurological Damage from this product..

I thought I was alone…I guess not!

First of all I find it outrageous that there have been this many complaints and yet the products are on the shelves. My story starts long before this site was even founded. I, like most of the other people on here, went grocery shopping a local supermarket and decided to pick up some HARTZ flea “medication” while I was there. I went home and applied the stuff according to directions to my cat who was about 5-6yrs old. Within hours i noticed my cat was lying on the ground and drooling at the mouth. Not long after that she started having seizures. she had seizures from that day forward until she died about 7 years later. Her last year she became very skinny and her rate of seizure increased, sometimes more than 1 a day. It was very hard to watch and i even thought about having her put to sleep at one point in time but i just couldn’t bring myself to do it because she had been my cat since i was a little girl. When she wasn’t seizing she seemed to be a happy and ordinary cat, loved car rides and sitting on the front porch. I knew she died from the hartz and despite years of dealing directly with hartz i have never received a penny in compensation for all of the vet bills or even a letter of apology, nobody at that company seams to care that they stole my cat from me! Even today, 5 years later, it still brings me to tears. I thought I was alone and that this was just some freak incident. That was until I found this site today. How many innocent animals have to suffer until this stuff it taken of the market. I wish I could be more helpful and tell everyone exactly what hartz product i used, but i threw the bottle away the same day i purchased it and have never looked at those products again. It seams however that there are many different products produced by hartz and they all have the same problems, so my advise to all it to STAY AWAY FROM ALL HARTZ PRODUCTS. If sharing my horror story can save just one animal that it is worth the tears I have shed while writing this.

9 month old baby…

My cat was born in my room, she was the first one to come into the world out of 5. She’s been perfectly healthy since day one. The other night I noticed fleas on her, so we picked up Hartz Flea and Tick from the local WalMart. The next morning I woke up and went looking for her as I do every morning, and found her lethargically laying in her litterbox. I ran over and scooped her up, noticing her back end was unresponsive and almost paralytic. I immediately went to the sink, and washed her down with Dawn soap and warm water, then dried her off. It’s been 3 hours and she is still sleepy and her pupils are huge. I’ll be taking a trip to the emergency vet later if there is no improvement. I am sick to think that all of these poor animals have suffered and nothing has been done about it. 🙁

Immediate Action for Pets

If you have used any type of over the counter spot on flea product  and notice your pet acting differently and you can not immediately take your  pet to a vet
If you notice you’re pet starting to act differently anywhere from minutes to a few hours. Immediately give your pet a through bath. Avoid extremes in temperature of water. Hot increases absorption and cold increases toxicity. Dawn dish soap is very good for this if you have it use it or other liquid dish soap. Make sure to get all the soap out of the fur and then dry your pet. Keep them inside and watch them carefully If they continue to act odd or you see any of the known adverse reactions listed below  get your pet to  a Vet ASAP
  Known Adverse Reactions –
* Excessive drooling
* Vomiting
* Dizziness or symptoms related to balance
* Convulsions or seizures
* Tremors of the extremities, twitching
* Hypo- or Hyperthermia
* Disorientation.
* Difficulties breathing
* Paralysis
* In extreme cases, death may result from prolonged seizure activity

Sounds like an allergic reaction

I have been using Hartz products since I got my dog in August 2010 and have had NO problems with them.  The products I have been using are as follows:  Hartz Groomer’s Best Waterless Shampoo and Hartz Ultra Guard Flea & Tick Drops.  I have read many posts from this website claiming that this product is killing animals.  I have come to the conclusion that there are 2 reasons why your animals may be getting sick.

(1) It could be an allergic reaction.  If only one of your animals is getting sick from using the same product, then one of them is allergic.  Yes, you need to see a vet and waiting only makes it worse!  Prolonged exposure to an allergen can cause death!

(2) Improper usage.  Please do NOT skip over this!  You might be thinking you are using the products as directed but after reading these posts, I have found many of them to be using them incorrectly.

(A) For the Hartz Flea & Tick Drops: make sure you get the right one!  They are based on your pet’s weight.  Also, when applying make sure you put the tip as close to the skin as possible.  It’s not supposed to be applied to fur! After you have made contact with the skin, slide slowly and gently from the back of the neck to the tail.  After you’re done, take a paper towel and dab the excess off the fur.  If you leave the excess medicine on your pets fur then there is risk that your pet will ingest it!  This is NOT good!

(B) For the Hartz Waterless Shampoo:  spray over entire coat, comb completely through, AND towel dry to remove excess soap!

Pets are like people.  People misuse products and have allergic reactions that make them sick but pets can’t talk so they can’t tell you what’s wrong.  If you’re pet is sick, you MUST see a vet!  I know they are expensive but you made the decision to get a pet and therefore it’s YOUR responsibility to take care of that pet!  I work in a restaurant and I invested in a pet insurance policy with Purina.  Whatever money I spend at the vet, I get 90% refunded.  If you love your pet, you will find a way to make sure they live a long and happy life.

Very Sick Kitty.

I have 3 cats, all of mature ages. They have recently become infested with fleas, so I went to the super-market last friday looking for flea drops for them. I found Hartz UltraGuard Onespot for eggs and flea larvae, and it was on sale, and I figured since it was sold in a large super market, it would probably be safe to use. I talked to my girlfriend about it, and told me that Hartz isn’t know for being a very effective product. I used the product specifically as directed, and put the drops directly between the shoulder blades and hoped for results. What I got was far worse. I went into the room they loll around in around 10pm on sunday night, and two of the cats came darting towards me as they knew it was dinner time. I didn’t see the third one up and about, so I looked for her. I saw her tail sticking out from the large bed they usually sleep under, and I went over to get her. I touched her tail and she curled in with it. I went under to grab her, and I felt her being very limp and became extremely concerned. I pulled her out and her eyes were as large as saucers, and she starting curling up and meowing frantically. I had no clue what was wrong with her, and the past few hours I have been trying to comfort her, as the nearest emergency vet is hours away, and the vet down the street opens early in the morning. I tried feeding her the wet food, and she was lapping at the gravy on it, and then she started meowing frantically and curling up as much as she could. She now shifts between laying there passively, with wide eyes and shallow breathing to frantically trying to call for help, and avoid whatever pain she is in. I looked up what could possibly wrong with her, or that if there had ever been problems with the Hartz product. I really should have researched this product more before using it. Once I saw that, I took the other 2 cats that wer I only hope that she does not pass away before I can get her to the vet clinic, and even then, that they can save her from this suffering.

The EPA Calls this Pest Treatment Ingredient a “Possible” Carcinogen

This summer, U.S. veterinarians will begin prescribing a brand new spot-on flea and tick preventive from Novartis Animal Health.

The product for dogs is called Parastar and the cat product is EasySpot. The active ingredient in these products is fipronil, an adult flea insecticide.

Per Veterinary Practice News:

“The Novartis family of parasiticides is defined by best-in-class medicine, so Parastar and EasySpot fit perfectly,” says Jason Drake, DVM, director of professional services at Novartis.

“Together with the heartworm preventive medicine that veterinarians choose most for their own dogs and the only systemic flea product with an insect growth regulator, the proven power of fipronil found in Parastar and EasySpot is a natural addition to the family.”

Below is a Vets  comment on the  above

These two products, Parastar and EasySpot, are the first spot-on products introduced by Novartis in the U.S. The company does make a spot-on product called Prac-tic, with the active ingredient pyriprole, but it isn’t sold in this country.

Other flea and tick products by Novartis include:

Capstar (nitenpyram) tablets for dogs and cats. This is a flea treatment, not a preventive. Kills adult fleas.

Program (lufenuron) tablets for dogs and tablets, suspension and 6-month injectable for cats. This is a flea preventive; the tablets and suspension are intended to be given monthly. Kills fleas before they reach the adult stage.

Sentinel (milbemycin oxime/lufenuron) tablets for dogs is a combination product for the prevention of fleas, heartworms, roundworms, hookworms and whipworms. Recommended dosage is monthly.

Apparently Novartis was leaving money on the table and felt the need to add a spot-on flea/tick preventive to their U.S. product portfolio.

Fipronil, the Active Ingredient in the New Novartis Spot-on Products
Fipronil is a relatively new broad spectrum insecticide that acts by disrupting the central nervous system of insects.

Fipronil is used in a wide variety of applications beyond flea products, including cockroach and ant baits, termite control, agricultural products, and products used on turf and golf courses.

According to Pesticide.org:

“Fipronil has a different mode of action than many common insecticides. It is ‘an extremely active molecule.’ In insects, it disrupts the nerves in the brain and spinal cord by interfering with the ability of these nerve cells to transmit nerve impulses. The result is uncontrolled activity leading to death of the insect.

Fipronil also disrupts nerves in animals other than insects, including humans, but it does not bind as tightly to these nerve cells as it does to insect nerve cells.”
Symptoms of fipronil toxicity in pets include:

Loss of coordination
Symptoms of exposure in humans can include eye irritation, headache, dizziness, nausea and weakness.

In laboratory animals, fipronil caused kidney damage, significant alterations in thyroid function, and aggressive behavior. The product Frontline, which contains fipronil, also altered the levels of sex hormones in those animals. The offspring of pregnant lab animals exposed to the insecticide were smaller than normal and took longer to sexually mature.

The U.S. EPA has classified fipronil as a possible human (Class C) carcinogen due to the development of both benign and malignant thyroid tumors in laboratory animals exposed to it.

Minute concentrations of fipronil can prove toxic to several animals including birds, lizards and fish.

Fipronil lasts for a minimum of 56 days on pets, and people can be exposed by petting an animal that has been treated with a spot-on product containing the insecticide.

When exposed to light, fipronil can break down into a molecule called fipronil-desulfinyl. Per the EPA, this breakdown product is approximately 10 times more toxic than the fipronil itself. It is also more easily absorbed through skin than fipronil.

EPA Warning about Spot-on Flea/Tick Products Remains in Effect

Two years ago, the EPA issued an advisory about ‘spot-on’ products applied to the neck or back of pets to prevent fleas and ticks. The advisory was the result of a dramatic increase in adverse reactions to these products – reactions ranging from mild skin irritation to seizures and even death.

Among the problems the EPA found with spot-on flea and tick products:

The majority of adverse reactions were in dogs under three years old and between 10 and 20 pounds. High risk breeds included the Chihuahua, Shih Tzu, Miniature Poodle, Pomeranian, Dachshund, Maltese, Yorkshire Terrier and Bichon Frise.

Adverse reactions in cats were often the result of the kitty being treated with a product designed for dogs or through exposure to a treated dog.

Cats treated with dog products had a very high rate of serious reactions, including fatalities.

Dosage ranges on many products were considered too wide, and product labeling in general was identified as a problem.
In my opinion, the risks of these products are simply too great to warrant their routine (monthly) use. I encourage my dog and cat owner clients to avoid regular application of these pesticides in favor of safer alternatives.
