Flea

Natural Habitat

Ectoparasitic on mammals and birds; often found in carpets, bedding, and pet sleeping areas within homes.

Diet & Feeding

Hematophagous (blood-feeding); adults feed exclusively on blood from their hosts, while larvae feed on organic debris and adult flea feces.

Behavior Patterns

Fleas are excellent jumpers due to powerful hind legs. They are agile and move easily through hair or feathers. They undergo complete metamorphosis (egg, larva, pupa, adult).

Risks & Benefits

Risks: Can cause intense itching, allergic reactions (flea dermatitis), and anemia in heavy infestations. Vectors for diseases like plague (Yersinia pestis), murine typhus, and tapeworms. Benefits: None to humans or pets; part of the food web for some predators.
