Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

I bought it because of trust in the Hartz name.

I read the label. It indicated that the item could be dangerous when used and couldn't be disposed with ordinary household goods or be returned for credit. You very nicely credited me when I made my complaint but said it couldn't be returned and couldn 't tell me how to dispose of it. I'm surprised it is still being sold. It has the one star to bring it to your attention, but I wouldn't give it that.
