Ingredients
Active Ingredients
GCP Flea, Tick, and Mosquito Deterrent chews are a natural supplement designed to make your pet unwelcoming to pests. Its efficacy is based on three natural, science-based mechanisms:
-
Thiamine (vitamin B1) Helps to reduce fleas on the skin by promoting the release of sulfur, which is toxic to fleas, through the skin. While Thiamine is highly effective in reducing fleas, ticks and mosquitos, it poses no danger to your pets. GCP contains more than 10x the thiamine of our competitors!
-
Apple Cider Vinegar Has been shown to safely repel insects by making your pet’s skin and blood more acidic. Fleas have also been shown to be deterred by the smell and taste of vinegar. Apple cider vinegar is effective in treating current pest infestations and helps to prevent new ones from occurring. It also works in conjunction with the lauric acid in coconut oil to repel pests.
-
Anise Emits an odor that’s not tolerated by fleas. When taken internally, anise deters fleas from biting your pets, and keeps infestation at bay.
More Vitamins, Minerals, & Good Stuff
- Niacin (vitamin B3) helps promote skin and coat health in dogs.
- Vitamin B12 works to ensure that your pet’s nervous system functions properly. It also promotes normal cell growth. Vitamin B12 helps to maintain the energy levels of dogs so they can enjoy active, full days.
- Vitamin E is a fat-soluble nutrient that is essential for a dog’s muscles, circulatory system, and injury healing. It’s also an antioxidant, helping to protect cells from damage caused by free radicals.
- Coconut Oil contains anti-inflammatory properties that promote skin and coat health. Lauric acid, the main component of coconut oil, also helps to deter pests from biting and infesting your pet’s skin. Coconut oil additionally soothes skin and prevents flea rash.
Quality you can trust
We manufacture our delicious GCP chews that successfully deters fleas, ticks and mosquitos without additives, binders, fillers, sugars, chemicals or pesticides.
We never include ingredients that can lead to severe allergic reactions in pets, such as geranium, lavender, pennyroyal oil or eucalyptus.
Our active ingredients are all vigorously tested and uniquely formulated to naturally repel fleas, ticks and mosquitos, while promoting overall great health and well-being for your pets.
We manufacture our supplements in the USA in an FDA approved facility. We personally see to it that every step of production is held up to the most rigorous manufacturing standards.
Frequently Asked Questions
How long does it take to start having an impact?
Our chews are designed to be used daily and build up deterrence over 30 days for full effect.
How often should I use this product?
This product is designed to be given to your dog daily to build up and maintain a first line of defense against fleas, ticks, and mosquitos.
What is the dosage?
Dosage is based on the size of your dog – 1 chew per 20 lbs. See the dosage chart above.
We already have an active flea infestation. Is this the right product for me?
Since our product is a preventative and deters pests over 30 days of daily use, we would recommend using other natural solutions such as flea shampoos first.
What about my cat? Can I use your product for my cat?
These chews are formulated for dogs but work for cats just as well. In our first run, cats didn't like the taste as much as dogs did, so we initially marketed it for dogs. If your cats aren’t finicky eaters, it should work just fine for you.
60 Day Money Back Guarantee
Our products come with a 60-day no-hassle guarantee. If your dog decides they don’t like the chews, or if it “isn’t working out,” we’ll refund you. Hassle free.Shipping Notes

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference.
Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design.
Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them
Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.
