Ok fellow MD'ers, please be careful of this product. Its fairly safe but dont go overboard with it. It will kill your pet cat just about as fast as it will kill ticks! But will not harm dogs( commonly used in tick and flea control for dogs). For many years I used permethrin based products to control bugs in my nursery and sprayed for one of the largest nursery in the states. Now if i get even close to the stuff I get very ill and end up sick in bed for a week. Again read the instructions and warnings carefully and HH

Oh!!! make sure to wash it all off before feeding your fish tank, it will kill all aquatic life and and all other cold blooded animals!
