Comparative speed of kill after treatment with Simparica₿/sup>(sarolaner) and Advantix®(imidacloprid᾿ permethrin) against induced infestations of Dermacentor reticulat
Background Ticks are common ectoparasites that infest dogs globally. Acaricides with rapid and sustained speed of kill are critical to control infestations and to reduce the risk of disease transmission. This study evaluated the speed of kill for 5 weeks after a single dose of orally administered Simparica™(sarolaner) against induced infestations with Dermacentor reticulatus on dogs, compared to Advantix®Spot-on solution for dogs (imidacloprid + permethrin).
