A flea is a small, wingless insect that feeds on the blood of mammals and birds. It has a laterally compressed body, enabling it to move quickly through the fur or feathers of its host. Fleas are known for their jumping ability, which allows them to move from host to host. They can cause itching and discomfort for their hosts, and in some cases, transmit diseases. Effective flea control measures often involve treating both the infested animal and its environment to prevent further infestations.
