Flea

Natural Habitat

Found globally in households, specifically on or near warm-blooded hosts like dogs, cats, and humans.

Diet & Feeding

Obligate hematophages (blood-feeders), consuming blood from mammals and birds.

Behavior Patterns

Fleas are wingless parasites known for their extraordinary jumping ability. They exhibit a life cycle consisting of egg, larva, pupa, and adult, often remaining dormant in the pupal stage until a host is sensed.

Risks & Benefits

Fleas are significant pests and vectors for diseases such as bubonic plague and murine typhus. They cause skin irritation and allergic reactions (flea allergy dermatitis) in both animals and humans.
