Dog Flea Stage (Larval/Pupal) or Plant Matter

Found in bedding, carpets, and floor cracks where pets rest; generally indoors or in shaded outdoor areas.

Larvae eat organic debris, particularly adult flea excrement ('flea dirt'); adults feed on host blood.

Larvae seek dark, humid areas away from light; they spin a silk cocoon to pupate and can remain dormant for weeks or months.

Risks include skin irritation, allergic reactions (flea allergy dermatitis), and potential transmission of tapeworms or pathogens. There are no known benefits to the ecosystem.
