Quick Scoop: Jiggers on the feet are tiny parasitic fleas, usually Tunga penetrans , that burrow into the skin—most often around the toes or under the nails—and cause itching, pain, swelling, and sometimes infection.

What they are

  • They are not normal “bugs on the skin”; the female flea embeds itself in the skin and grows as it fills with eggs.
  • They’re often linked with walking barefoot in sandy, dusty, or unsanitary areas, especially in tropical and subtropical regions.

What it looks like

  • At first, it may look like a small black dot or a tiny spot with itching and irritation.
  • As it grows, the area can become a painful bump, swollen, red, and hard to walk on.

Why it matters

  • If untreated, jiggers can lead to open sores, secondary bacterial infection, difficulty walking, and in severe cases serious complications like tetanus or gangrene.
  • The safest approach is medical removal and wound care rather than trying to dig it out yourself.

Prevention

  • Wear closed shoes or sandals.
  • Keep feet clean and dry.
  • Avoid walking barefoot in high-risk areas.
  • Get prompt care if you notice a suspicious painful bump or black dot on the foot.
