Quick Scoop

Jiggers are caused by a tiny parasitic flea called Tunga penetrans, which burrows into the skin, usually through the feet, especially when people walk barefoot in infested soil. Risk is higher in places with poor sanitation, dirt floors, overcrowding, and close contact with infested animals.

What causes them

• Walking barefoot on sandy or soil-based ground where the flea lives.

• Poor hygiene and sanitation, which make infestations more likely and harder to control.

• Dirt floors, crowded housing, and limited access to healthcare.

• Animals can also carry the flea and help keep it circulating in the environment.

Why it matters

Once the flea enters the skin, it can cause itching, pain, swelling, and open wounds. If those wounds get infected, the problem can become much more serious, including skin infection, tissue damage, or tetanus risk.

Prevention

• Wear closed-toe shoes.
• Keep living areas clean.
• Avoid walking barefoot on soil or sand.
• Treat infested animals and improve sanitation.

Bottom line

So, the short answer is: jiggers are caused by infestation with the chigoe flea, and the main drivers are barefoot exposure to contaminated soil plus poor living conditions. If you want, I can also explain the symptoms or how jiggers are treated.
