Common Flea

Inhabits the fur and skin of mammals (cats, dogs, humans) and lives in household carpets, bedding, and floor cracks during larval stages.

Adults are hematophagous, feeding exclusively on the blood of mammals or birds. Larvae feed on organic debris and adult flea feces (flea dirt).

Fleas are wingless, saltatorial insects capable of jumping long distances. They undergo complete metamorphosis: egg, larva, pupa, and adult. They are highly active and jump toward heat and carbon dioxide sources.

Risks include painful, itchy bites, allergic dermatitis, and the transmission of pathogens such as tapeworms or Bartonella. They provide no significant benefits and are considered household and veterinary pests.
