For cats and dogs.

Sentry Natural Defense Natural Flea & Tick Spray kills fleas, ticks, mosquitoes and other unwanted pests for up to four weeks, yet it’s safe to use on your pets and around your family when applied as directed. Each bottle contains 8 oz. of natural active ingredients such as peppermint oil, cinnamon oil, lemongrass oil, clove oil and thyme oil.

How Does Natural Defense Work?

Certain plants contain compounds that give them the ability to defend themselves against insects. Natural Defense is a synergistic blend of botanical extracts including peppermint oil, cinnamon oil and lemongrass oil. This combination of oils significantly enhances the pesticidal activity of Natural Defense. How? Octopamine!

Octopamine is a key neurotransmitter found in insects, it is the insect's equivalent of adrenaline. It regulates their heart rate, behavior and metabolism. The unique molecular structure targets and blocks octopamine neurotransmitter receptors in insects. Blocking octopamine results in a total breakdown of the insect's central nervous system. As mammals, fish and birds have no receptors for octopamine, the ingredients do not have this affect on them... or people!

Available in 8 oz liquid that comes in a spray bottle.

Suggested Use

  • Start spraying the animal at the tail, making sure to spray the entire coat of the animal, including legs, tail and underbody.
  • With you hand, fluff the hair against the way it normally lays to assure that the spray penetrates the coat to the skin.
  • Do not saturate the animal. and do not spray in the face, eyes, or genitals.
  • Apply once a month or if a severe issue apply no more than every 2 - 3 weeks

Caution

PLEASE NOTE

We have had some reports of reactions in cats such as skin irritation and hair loss after application (see reviews below). We recommend testing the product initially by applying the spray in a small area like the nape of the neck, and waiting 24 hours to evaluate any response before giving your cat a full application of the spray. If you do see an adverse reaction, wash your cat with a shampoo or dishwashing liquid that contains detergents, as this is the most effective way to remove the oils causing the reaction.

While we understand that this product is not perfect since some cats do have an allergic reaction, we do believe it is far safer than the chemical based insecticide products. The long-term use of systemic chemical pesticides often leads to far worse problems than a skin reaction (see The Natural Approach to Flea Control). The number of cats that have a reaction to the Sentry Flea & Tick products is small, and for the majority of cats this product is safe and effective. We choose to continue offering this product because we believe that providing a safer alternative to the chemical pesticides is an important service for those cat owners who prefer to use this type of insect control product.

            The spray says apply to pet but do not saturate. How are you to do this? In order to reach undergrowth of hair, saturation is necessary. The smell is much too strong - cat found it offensive as did I.

                The smell was so overpowering with this product that I never used it. I wouldn't have been able to use it on my dog, because I would have been sneezing all day. It might be just me, I might be allergic to it.

                Comments about Sentry Natural Defense Flea & Tick Spray:

                I don't know about long-term effectiveness, but when I sprayed this directly on a flea, it immediately stopped moving and died. I think it would work best to prevent dogs from picking up pests on walks or to kill fleas that are on a dog. It is pretty greasy and will stain white fur, so that is a minor downside.

                  I use this on two cats and a mini dachshund. the only warning that needs to be given people is that with this product MORE is NOT Better.. use it sparingly. 1-2 sprays will easily cover a small dog. I went and got a fly spray mitt for horses ( its just fake sheep skin with a plastic liner).. I spray it 2 times and then rub the mitt over both the cats and the dog. I tried it on the ears, legs and bellys of my horses as well. Its doing a bang up job of keeping the horse flys off of them and the deer flys.

                        Comments about Sentry Natural Defense Flea & Tick Spray:

                        I bought this product even with the so-so reviews and am very disappointed. The odor is VERY strong, and not particularly bad, but very strong and long lasting. I sprayed this stuff on my dogs (and didn't even saturate as instructed) 24 hours ago and the smell still lingers. This spray also left grease marks wherever I sprayed it. It has made any and all dirt and pollen stick to the places where it was sprayed.

                            Sentry Natural Defense Spray is very effective. I highly recommend it, but have to stress one point. Before using it on your pet, you have to do a small patch test first to check for any sensitivities or reactions. I used a cotton swab dipped in the spray then wiped a VERY tiny patch (not much larger than the tip of the swab) of fur on each of my Chihuahuas. I did that prior to using the product, and one of my two Chihuahuas did have a reaction to the product, the other did not. I highly recommend this product. It works very well, but you have to do a small patch test first. Only Natural Pet Store also recommends doing a patch test as well.

                            I use this product twice a week on my Chihuahua (along with the Only Natural Garlic pills). I apply it using a cottonball, covering the same areas mentioned in the directions. She has been flea free for months, not one flea or flea egg. The smell is quite noticeable, but it is pleasant; I really like it. My dog doesn't mind the smell at all. Also, due to the smell of the spray, that is another reason to do a small patch test on your pet as well, that way you will know if it is to your liking or not without dousing your entire pet's body with it.

                            So for pets, who aren't sensitive to it, Sentry Natural Defense Spray is definitely one of the best out there.

                              Comments about Sentry Natural Defense Flea & Tick Spray:

                              I think if you were to spray a few times on a kitty's back every couple of weeks before she goes out to romp in the grass it could be a great product.

                              HOWEVER, I bought this as a flee treatment and now my little girl cant keep her food down, is drowsy and sad, and has a temperature (hot ears). We're on our way to the vet in an hour so hopefully she will be feeling better soon. I think I'll request a new flee treatment even one not so 'natural' as she is certainly not feeling very 'natural' right now.

                              I don't know how from 8"-12" and without saturating, you could possibly make sure it gets down to her skin, but DO NO SATURATE!!!

                              the spice sent smells good though
