Flea Infestation in Animals

Fleas cause direct harm to their hosts' skin inducing discomfort and stress. They also serve as potent vectors of various diseases. Out of over 2,500 identified flea species, three primarily feed on birds and pets. The most prevalent species is the cat flea, Ctenocephalides felis, commonly found on both dogs and cats worldwide while dog flea, Ctenocephalides canis is found in dogs. The chicken flea, Echidnophaga gallinacea and human flea, Pulex irritans, are also globally distributed but at lower rates. These fleas are not highly specific to particular hosts, allowing them to infest companion animals, humans, and wildlife alike. High rates of flea infestations, known as pulicosis, are common among dogs and cats, making treatment and prevention a key focus in veterinary care.
