No, Fiprotec alone does not directly kill flea eggs. However, it offers valuable protection against future flea infestations in two ways:
Eliminating Adult Fleas: Fiprotec's primary active ingredient, fipronil, is a potent insecticide that quickly kills adult fleas on your pet within 24-48 hours. By breaking the breeding cycle of adult fleas, you significantly reduce the chances of new eggs being laid.Inhibiting Development: While Fiprotec itself doesn't directly kill flea eggs, it contains another key ingredient called s-methoprene, which acts as an insect growth regulator (IGR). S-methoprene disrupts the hormonal development of flea eggs and larvae, preventing them from maturing into biting adults. This effectively halts the next generation of fleas from infesting your pet and your home.Therefore, while Fiprotec doesn't directly kill existing flea eggs, its potent action against adult fleas and its inclusion of an IGR provides a powerful two-pronged approach to prevent future outbreaks. Remember, consistent application every 4 weeks is crucial for optimal protection and to break the flea breeding cycle completely.
