Frontline Tri-Act Spot-On Flea Treatment for Dogs has a unique formula that kills faster and repels more disease-carrying biting insects. Used every 4 weeks, it is the next level in biting insect control for dogs, providing long-lasting protection against flying insects as well as fleas and ticks whilst also preventing home flea infestations by killing fleas before they can lay eggs.

Frontline Tri-Act Flea Treatment starts killing fleas in just 5 minutes and kills newly arriving fleas and ticks on your dog within 6 hours. It also keeps working for the whole duration of treatment.

The spot-on flea treatment also kills mosquitoes, biting flies and sand flies. Repels flying insects for up to 5 weeks to prevent them from biting and helps reduces the risk of tick-borne diseases. Repels ticks for 4 weeks. Tri-Act treatment formula is water-resistant after 48 hours so your dog can enjoy occasional swimming and bathing and still stay protected.
