Capstar

Capstar For When Fleas Attack

Capstar is the go-to solution for pet owners who need to kill fleas right away. Unlike monthly treatments that can take hours or days to work, Capstar is a pill made for speed. It was created to stop an active flea problem in its tracks. This makes it a key tool for helping itchy, miserable pets feel better fast. Capstar is now part of the PetIQ family, but it still works the same way: fast, safe, and available without a prescription.

The active ingredient in Capstar is called nitenpyram. It works by targeting the flea's nervous system. It goes into your pet's blood. When a flea bites the pet, it swallows the medicine and gets paralyzed within minutes. This fast "knockdown" effect is what makes Capstar different from almost every other product.

Capstar is for the pet owner in a panic. It is for the person who just found fleas on their dog after a walk in the park. It is for the cat owner who found a new kitten covered in bugs. It is not a monthly prevention pill. Instead, it is like an "emergency brake" you pull to stop fleas instantly.

Why Capstar Works

Works Fast: Capstar starts killing fleas within 30 minutes for dogs and cats. Studies show that within just 6 hours, it kills almost all the adult fleas on the animal. No other store-bought product works this fast.

No Messy Residue: Since it is a pill, there are no greasy spots on your pet's neck and no chemical smell. You can touch, hug, and play with your pet right after giving them the pill.

Safe for Young Pets: Capstar is safe for puppies and kittens as young as 4 weeks old, as long as they weigh at least 2 pounds. This makes it one of the few safe choices for very young animals.

Use as Needed: There is no strict schedule. You can safely give Capstar as often as once a day if your pet gets fleas again. This lets you fight the problem hard until your home is flea-free.

Works with Other Treatments: You can use Capstar along with monthly flea preventatives (like drops or collars). It acts as a perfect "add-on" to clear the current fleas while the long-term product starts to work.
