Bests & Worsts Reviews from Amazon

I've used this product for years. It has 2 main ingredients. The first one kills live fleas and the second one (METHOPRENE) kills the flea EGGS! IF YOU DON'T KILL THE EGGS YOU'LL ALWAYS HAVE FLEAS! I have dogs and cats. Some reviewers wrote that its not safe for cats-NOT TRUE! The first ingredient (Permethrin) is made from the flower buds of mums. Cats find it unpleasant but it won't hurt them as long as you don't apply it on them. Zodiac is part of a 3 stage system for killing fleas. The other 2 steps are a topical treatment (Frontline Plus with Methoprine, and Capstar. Capstar is a pill that kills ALL FLEAS ON YOUR PET without doing any harm to them at all. Capstar is used in my clinic and shelters to kill fleas on infested animals. Capstar will NOT kill eggs and only lasts 24 hrs so apply the Frontline a day before. With dogs I just put it in a piece of cheese and they eat it. Cats are fussier so you can crush the pill and mix it in their food (tuna works best) but I'm a Vet so I know how to slide it down a cats throat. Once given Capstar, put your pet in an enclosed space (the bathroom) for an hour or two and you'll see dozens of dead fleas on the floor. Some will still be alive so sweep them up with a vacuum and spray the entire area with ZODIAC immediately. A final tip: Fleas are easily killed by HEAT or COLD. Wash infected sheets, clothing, and put in Dryer on HIGH HEAT for an hour. Pillows and children's stuffed animals can be put in your FREEZER for 2-3 hours and all Fleas and Eggs will die. I hope this review helps with your flea problems. Remember, Neuter your pet!
