Trusted Flea and Tick Protection. FRONTLINE® Plus for Cats kills adult fleas and ticks, prevents new infestations by killing flea eggs and larvae to break the flea lifecycle, and lasts for a full 30 days.

Frequency Of Application Although FRONTLINE ® PLUS can control fleas for up to three months, if there is a high risk of reinfestation or if the pet has fleas which may cause flea allergy dermatitis, a once monthly application may be needed.

From the very first application, FRONTLINE kills 98–100% of existing fleas in less than 24 hours and continues to provide fast-acting, long-lasting flea and tick control.

Frontline Spray provides long-lasting, effective control of fleas and ticks on your pet. It kills up to 100% of existing fleas in less than 24 hours. Frontline Spray continues killing fleas for an entire month or more.

FRONTLINE PLUS®, FRONTLINE TRI-ACT® and FRONTLINE® SPOT ON kill fleas by affecting their nervous system, making them hyperactive before dying. These dying fleas often rise to the top of the pet's coat and bounce, so if you see fleas after treatment, it's often a sign the product has got to work.

Spot-on products may be less effective if they are not applied correctly, if the pet is bathed or goes swimming or out in the rain, or if the coat is very thick and dense. Cats and dogs that groom a lot may gradually reduce the concentration of spot-on products in their skin and coat.

Incorrectly applying topical flea prevention is the most common cause for why it's not working. Topical medication should be applied directly to the skin, not to your pet's fur. You must part their hair so you can apply it to the skin.

And FRONTLINE PLUS® not only kills fleas, but also stops flea eggs from hatching and infesting your home. How often can I use FRONTLINE ® SPOT ON? Use FRONTLINE® SPOT ON every 4 weeks for optimal protection against fleas and ticks.
