How Are Fleas Created?
WouterFleas are ectoparasites that can live and reproduce on many different animals. Their compact bodies make them capable of moving through feathers and hairs and are also known as “cuddle bugs”. Fleas are also known for their jump-like ability and mouthparts, which help them to attach to their host.
Fleas develop from eggs to adulthood through several stages. The larva stage lasts two to three weeks, feeding on small arthropods. The third instar larva spins a cocoon, which contains grains of sand and debris. The cocoon also helps the pupa camouflage itself. When it is complete, the adult flea emerges almost colourless. Fleas feed several times throughout the day. The larvae are often attracted to pet food, which is why they are attracted to your pet.
Fleas likely originated as hitchhikers from small mammals. The most common species are Ctenocephalides felis and Ctenocephalides canis. Before humans discovered the fleas’ ability to cause disease, they were thought to be harmless, but they were often transmitted by pets, especially cats.
Fleas are a nuisance for pets, and a few species can cause human disease. Among these, two species cause cat scratch disease and are the primary reservoir of the parasite. Fleas can also cause allergic reactions.
