Hartz UltraGuard Plus Flea and Tick Spray for Dogs, 10-Ounce


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.

Flea Lifecycle

For every visible adult flea there are many more flea eggs, larvae and pupae in the surrounding environment that you do not see.

Treating infested areas as soon as the problem is recognized is vital in stopping the flea life cycle.
