Flea And Tick Defense, For Dogs and Cats, 8 fl oz (237 ml)

A repellent to help protect your pets from fleas, ticks, mosquitoes, and flies. Fleas, ticks and mosquitoes are more than an itchy nuisance – they can carry and transmit potentially harmful bacteria, viruses and even tapeworms to your cat or dog. The traditional veterinarian industry’s answer to the growing flea and tick crisis is to use harsh chemical-laden products. These products can contain one or more potentially hazardous ingredients, including proven neurotoxins and one officially classified as a “Group C – Possible Human Carcinogen." The ingredients in regular flea and tick repellent products can work their way to your pet’s bloodstream and organs, sometimes within minutes of application. Our flagship pet pest repellent product, Flea & Tick Defense, provides a worry-free alternative that doesn’t rely on harsh, potentially hazardous chemicals. Based on a formula created in the Amazon rainforest, where fleas, ticks and mosquitoes are a way of life, Flea & Tick Defense uses a special blend of “pet-friendly,” yet “pest-unfriendly” natural Brazilian oils. This unique formula: Contains a rich blend of oils, including Lemongrass, Cinnamon, Sesame and Castor Oils, expertly blended and balanced with purified water. Is designed for short-term use, and for best results, reapply every two to three days, and after swimming, bathing or exposure to heavy rain. Is ideal for protection during an occasional walk in the woods, day hike or weekend camping trip.

Second purchase! A must!

This is the second time i purchase this product, I was scared at first using it for my cat as i don't like to use anything on her that she might lick but i decided to follow what other people said, I spray 1 or 2 sprits on a cotton pad then damp it with some water in order to dilute it then i only apply it on my cat's neck (back) where she won't be able to lick. It got rid of all fleas she had, i only used it every now and then again as I don't like to use stuff on her. I also used it around the house (behind doors) or places she won't get into. The smell is strong but not bad, smells citrusy. The bottle will last forever, you really only need a small amount. mine just expired so I repurchased, this way i have it if i ever need it during the next 2 years.

It smells not so nice, well, like cloves, but it works!!! Fleas and flies stayed away from my dog during this summer. Also I was spraying it on my windows, against mosquitos 😊 and it really worked. I absolutely love this spray because it contains natural ingredients. Really good value also, you only need few sprays.

Great

This is my third time ordering this spray. 🐾 I use it regularly for my dog. The scent is herbal but not overpowering, and I feel safe using it because it’s made with natural ingredients.

The formula seems gentle on the skin, and I haven’t noticed any irritation or discomfort on my pets, which is a huge relief. The packaging is convenient, sturdy, and easy to store, with a secure cap that prevents leaks. The product is very effective at keeping both fleas and ticks at bay, providing noticeable relief within a few hours of application. Overall, the quality is very good.

Dog loves to roll in grass. While it didn't block all fleas, it did cut down on the amount. Works best after using a flea shampoo to help extend effectiveness. All natural ingredients are safe for my dog's sensitive stomach. Fragrance is strong, but I don't mind and dog seems fine with it.
