Frontline

Frontline starts to work quickly and is generally reported to kill fleas within about 24 hours and ticks within around 48 hours of application. You may still see live fleas for a short time as they are killed and as new ones hatch from the environment.

Yes, Frontline is designed to kill adult fleas on cats and dogs. Because most of a flea problem lives in the home rather than on the pet, treating your pet alongside a household spray and regular cleaning gives the best results.

The active ingredient spreads over the skin and coat and collects in the natural oils, killing fleas and ticks that come into contact with it. It works from the outside of the animal rather than being given as a tablet.

Frontline Spot On is typically applied to dogs once a month, but always follow the interval and dose on the pack for your dog's weight. Do not apply it more often than directed, and use the dog product only on dogs - never on cats.

A single application is generally intended to give flea protection for around four weeks, with tick protection for a shorter period, which is why monthly application is usual. Check your specific product's leaflet for the exact timings.

Yes, Frontline is used to kill and control ticks on cats and dogs as well as fleas. If you find a tick, follow the product guidance, and ask your vet about safe tick removal and any risks in your area.
