Natural Habitat

Typically found on domestic pets, in carpets, upholstery, bedding, and floor cracks within homes.

Diet & Feeding

Obligate hematophages; adults feed on the blood of mammals (such as humans, cats, and dogs), while larvae feed on organic debris and 'flea dirt' (dried blood excreted by adults).

Behavior Patterns

Wingless and vertically flattened to move easily through hair or fur. They are known for powerful jumping abilities and go through a four-stage life cycle: egg, larva, pupa, and adult.

Risks & Benefits

Risks include itchy bites, allergic dermatitis, and potential transmission of diseases like murine typhus or tapeworms. They do not provide ecosystem benefits and are considered a significant domestic pest.
