Certifect for Dogs 10-20 Kg ( 23-44 lbs) is Merial's new long-lasting, monthly topical flea and tick preventative. It works just like Frontline Plus with the addition of amitraz, a powerful tick-killing ingredient. It kills ticks and adult fleas rapidly and destroys the flea life cycle by killing flea eggs and larvae as well. Most topical tick treatments can take 24-48 hours to kill ticks, but Certifect for Dogs begins killing ticks in 6 hours and kills up to 100% of ticks in 18 hours. Furthermore, it is the only topical tick product that forces ticks to detach from an infested host. Certifect for Dogs provides complete flea control by killing adult fleas and preventing development of all flea stages. It not only kills fleas and ticks rapidly, but it continues to protect dogs from fleas and ticks for a whole month - even when swimming or bathing. In addition, Certifect for Dogs kills chewing lice and can also be used to control chewing lice and sarcoptic mange infestations.
