Natural Habitat

Fleas are typically found on warm-blooded animals such as cats, dogs, and other mammals, including humans. They also reside in carpets, bedding, and cracks in floors, especially in areas frequented by their hosts.

Diet & Feeding

Adult fleas feed exclusively on the blood of their hosts (hematophagous). Larvae feed on organic debris, including adult flea feces (flea dirt).

Behavior Patterns

Fleas are wingless insects known for their ability to jump significant distances, aiding in host transfer. They lay eggs on the host, which then fall into the environment. The lifecycle includes egg, larva, pupa, and adult stages. Adults are attracted to warmth, vibrations, and carbon dioxide from potential hosts.

Risks & Benefits

Risks include causing itching, skin irritation, allergic reactions (flea allergy dermatitis) in pets, and can transmit diseases such as tapeworms (Dipylidium caninum) and Rickettsia typhi (murine typhus) to humans. They are generally considered pests with no significant benefits to humans or ecosystems in domestic environments, though they are part of the food chain for some predators.
