DescriptionAdult Dog fleas feed on the blood of dogs and cats, and they occasionally bite humans. It is a carrier of the Dog Tapeworm, Dipylidium caninum, which can also affect humans. The body is laterally flattened, which allows it to move easily through an animal’s fur. Spines project backwards from the body of the flea, which help it to hold onto the host animal during grooming. As they can jump approximately 6 inches, they can move from host to host. They can also infest garden lawns. The fleas go through a four–stage life cycle: eggs, larvae, pupae, adult. The larvae are longer than the adults and feed on particles of dry blood, excrement, and organic substances
