## Description

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.

Review: A product that does what it says it will. - This is the stuff. Many, many years ago, we bought a house that was absolutely infested with fleas. We bombed the place, and then used this spray occasionally to keep them from coming back. It worked like a charm. I still use it on pet bedding during the summer months so that there won't be a surprise infestation. It smells like floor wax. Very pleasant.
