Hartz UltraGuard Plus Flea and Tick Spray provides immediate relief for your dog or cat from fleas and ticks. The fine mist continues to kill fleas and ticks for seven days and prevents reinfestation and flea build-up for a month.
Fleas can lay up to 50 eggs a day, so it’s important to use a formula that breaks the flea life cycle. UltraGuard Plus products contain insect growth regulators (IGR) which kill flea eggs, larvae and pupae to halt current infestations and prevent future reinfestations.
Be sure to always use dog products on dogs and cat products on cats; they cannot be used interchangeably.

I haven't had it long enough to give it a top rating as I've only used it a couple of times to date. So far it works quite well.

If you spray the dog and rub it in some, the flees disappear fast. It lasts a week or more. I recommend the Hartz Home Spray also. Spray carpet and furniture. Wait half an hour and vacuum. If you vacuum every week your flee problem will go away.
