Cat Fleas & Dog Fleas


There are dozens of different species of fleas, but the Cat Flea (Ctenocephalides Felis) is by far the most common flea on pets and in structures in the United States. All fees are similar in appearance, as wingless insects with bodies flattened from side to side and with long hind legs for jumping. They are black to reddish black in color and have spiny legs as well as rows of spines along other body areas called “combs”. These combs are important for identification of the species. The genal comb is a row below the head, and the pronotal comb is a row behind the head, at the back of the pronotum. The Cat Flea has both combs, it has eyes present, the genal comb is horizontally placed, and the first two spines on the genal comb are the same length. These characters separate it from the similar Dog Flea. Flea larvae are rarely seen, but they are legless and whitish with a brown head, unless they have fed on fecal matter from the adults, in which case they assume a reddish color. They are covered with short hairs, and when disturbed are able to flip about violently in order to escape
