Natural Habitat

Found globally in homes, outdoor areas with high animal traffic, and directly on host animals like cats, dogs, and rodents.

Diet & Feeding

Adults are hematophagous, meaning they feed exclusively on the blood of birds and mammals. Larvae feed on organic debris, especially 'flea dirt' (dried adult excrement).

Behavior Patterns

Fleas are wingless, laterally flattened insects capable of jumping long distances. They undergo complete metamorphosis (egg, larva, pupa, adult) and spend most of their adult life on a host.

Risks & Benefits

Fleas are significant pests that cause itching, dermatitis, and allergic reactions. They are vectors for diseases such as bubonic plague, murine typhus, and can transmit tapeworms to pets and humans.
