Hartz UltraGuard Plus Flea and Tick Collars kill fleas, flea eggs and ticks for up to seven months. Hartz Flea and Tick Collars are the most cost effective, complete protection against fleas and ticks -- which is probably why Hartz collars are the #1 best selling flea and tick protection product. Collars can be cut to fit your pet and still provide protection even after getting wet.
Fleas can lay up to 50 eggs a day, so it’s important to use a formula that breaks the flea life cycle. Hartz UltraGuard Plus products contains insect growth regulators (IGR) which kill flea eggs, larvae and pupae to halt current infestations and prevent future reinfestations.
Dog collars can be used on puppies six weeks of age or older. Cat collars can be used on kittens 12 weeks of age or older. Be sure to always use dog products on dogs and cat products on cats; they cannot be used interchangeably.
