Ectoparasiticides Used in Small Animals: Overview

Flea and tick infestation of dogs and cats is a major health problem to the animals and an economic burden to their owners. Traditionally, a wide array of ectoparasiticides has been available, and switching among brands was frequent, leading to problems in achieving acceptable external parasite control. Veterinarians are uniquely qualified to provide key advice on host/parasite interrelationships and selection of the most suitable program. However, many pets owners have historically purchased their flea and tick products in supermarkets or pet supply shops where professional advice is not available. Fortunately, recent advances in product technology and in our understanding of flea and tick epidemiology have dramatically altered the purchasing patterns of pet owners. Veterinarians should become aware of these technological improvements in both insecticidal chemistry and delivery systems and encourage client education by their staff.
