Cat Flea (or general Flea)

Natural Habitat

Found worldwide in association with mammals and birds. Indoors, they live in carpets, pet bedding, upholstered furniture, and cracks in flooring.

Diet & Feeding

Adults are parasitic and feed exclusively on the blood of hosts (cats, dogs, humans, wildlife). Larvae feed on organic debris, particularly the dried blood feces ('flea dirt') left by adults.

Behavior Patterns

Fleas are wingless but are powerful jumpers, capable of leaping great distances relative to their size to reach a host. They undergo complete metamorphosis (egg, larva, pupa, adult). The pupal stage can remain dormant for months until vibration or heat signals a host's presence.

Risks & Benefits

Risks: Their bites cause intense itching, allergic reactions (flea allergy dermatitis), and potential secondary infections. They are vectors for diseases such as murine typhus and can transmit tapeworms to pets. Benefits: None in a domestic setting; they are significant pests.
