Controlling fleas

Stop the infestation before it starts.

Unlike other flea treatments that only control adults, SENTINEL® SPECTRUM® (milbemycin oxime/lufenuron/praziquantel) and SENTINEL® (milbemycin oxime/lufenuron) FLAVOR TABS® break the life cycle to prevent fleas from infesting your pet and your environment.1

The Companion Animal Parasite Council recommends year-round flea treatment throughout your dog's life to protect against flea infestations on your dog and in your home.2

With SENTINEL SPECTRUM and SENTINEL FLAVOR TABS, when fleas bite your dog and feed on its blood, they also feed on lufenuron—the unique ingredient in SENTINEL® Brand Products.

  • Is not light sensitive
  • Cannot be washed off
  • Is evenly distributed throughout the pet's system


Lufenuron, a unique ingredient found in SENTINEL
Brand Products, prevents fleas from developing into adults.
