The answer to 'types of flea' is that there are several common types of fleas that can infest homes and pets. The most prevalent is the cat flea (Ctenocephalides felis), which can feed on both cats and dogs, as well as humans. Other types include the dog flea (Ctenocephalides canis), the human flea (Pulex irritans), and the rat flea (Xenopsylla cheopis), which can transmit diseases like the bubonic plague.
Fleas are small, wingless insects that survive by feeding on the blood of their host. They can jump up to 13 inches high and are adept at moving quickly through fur and fabrics. Fleas go through a life cycle of egg, larva, pupa, and adult, with the entire process taking as little as 2-3 weeks in ideal conditions.
