It's normal to still see fleas on your dog after applying Frontline, as it takes time for the treatment to kill fleas and completely clear an infestation. Fleas can appear to be more active before dying.
- Frontline starts killing fleas within 4 to 12 hours.
- It may take up to 24 hours for a noticeable reduction in flea activity.
- Complete elimination of fleas may take a few days.
Frontline contains an active ingredient that spreads through your dog's natural oils, killing fleas upon contact. However, it is normal to still see fleas as they take time to come into contact with the treatment and die. If your pet continues to scratch vigorously or if fleas persist for more than a week, it might be worth consulting a vet to ensure there are no underlying issues or to discuss different flea control solutions.
