Both products kill fleas and ticks on your pet, however our most advanced formula FRONTLINE Plus also stops flea eggs from hatching and infesting your home.
You can handle, stroke and cuddle your pet as usual as soon as the application site is dry. In the meantime treated animals should not be handled and children should not be allowed to play or sleep with them.
No, FRONTLINE Plus®, FRONTLINE Tri-Act® and FRONTLINE® Spot On act topically which means that fleas and ticks are killed through contact with your pet's skin and coat so they do not need to bite to be killed.
