Jigger Fleas, also known as chigoe fleas (Tunga penetrans), are parasitic insects that burrow into the skin of their hosts, including humans and animals. They are considered medically significant pests due to their ability to cause painful lesions and secondary infections.
Identification
Adult jigger fleas are extremely small and difficult to see. Once embedded in the skin, the female flea enlarges significantly, forming a visible lesion.
Habitat and Distribution
They are commonly found in tropical and subtropical regions, particularly in sandy soils and areas with poor sanitation.
Life Cycle
The female burrows into the skin to lay eggs, which are released into the environment. Larvae develop in soil before becoming adults.
Damage and Impact
Infestations cause itching, pain, and inflammation. If untreated, they can lead to infections and more serious complications.
Signs of Infestation
Small, painful lesions—often on feet—are the most common sign.
Prevention and Control
Wearing shoes, maintaining hygiene, and avoiding infested areas help reduce risk.
