Dog Flea

Natural Habitat

Typically found on domestic dogs and cats, but also in carpets, bedding, and floor cracks where pets sleep.

Diet & Feeding

Obligate hematophages; adults feed on the blood of mammals, while larvae feed on organic debris and adult flea feces (flea dirt).

Behavior Patterns

Fleas are wingless, powerful jumpers that utilize specialized hind legs to move between hosts. They undergo complete metamorphosis (egg, larva, pupa, adult) and can remain dormant in the pupal stage for months until triggered by vibration or heat.

Risks & Benefits

Risks include painful, itchy bites, allergic dermatitis in pets, and potential transmission of tapeworms (Dipylidium caninum). They provide no significant benefits to the ecosystem or humans and are considered a household pest.
