What is a flea?

Fleas are small, wingless insects that are external parasites of mammals and birds. They survive by feeding on the blood of their hosts, often causing itching, discomfort, and sometimes allergic reactions. Fleas can also transmit diseases and tapeworms, making them a concern for both pets and humans. Their life cycle includes egg, larva, pupa, and adult stages, and they are known for their remarkable jumping ability. Effective flea control includes treating pets, their environment, and preventing reinfestation.
