100% ORGANIC and NON-TOXIC. This means that it is safe for your hunting dogs, you, and your family! It is effective in eliminating FLEAS, TICKS, LICE, FLIES, and MITES both on your dogs and in their bedding areas, kennels, and yards. Here is how it works....Buck Mountain Parasite Dust's main ingredient is Organic Neem which contains a compound called Azadirachtin. This compound affects arthropods (fleas, ticks, lice, flies, and mites) in 3 ways. First, it is an anti-feedant which means it makes the parasites unable to feed or bite. Second, it disables their ability to molt their exoskeleton which causes them to begin to dehydrate and suffocate. Third, it is an insect cell growth inhibitor which stops eggs from hatching and also aids in dehydration. All this works together to kill both parasites and their eggs completely in around 24-48 hours. This product is safe and can be used in kennel, stable, home, office, clinic, yard, or even your garden. You no longer have to worry about harmful side-effects of commonly used chemicals or them coming in contact with you or your family. Three ounce powder can.
