Can sand fleas infest humans?
Can sand fleas infest humans? People who live in or visit tropical or subtropical areas that have sand fleas are most at risk for tungiasis. This painful, itchy skin lesion occurs when a sand flea burrows into your skin to lay eggs. Tungiasis is common in impoverished areas.
How long do sand fleas stay on you?
The adult female sand flea burrows into the skin and grows 2000 times in size as eggs develop. The female flea typically lives for 4–6 weeks, during which the eggs are expelled and fall to the ground.
How do you know if you have sand fleas under your skin?
You probably won't notice when the female sand flea first enters your skin. Once it burrows into your skin, you may see a white circle that looks like a ring or halo with a black dot in the center. Over time, the black dot grows as the sand flea gorges on blood and gets bigger with eggs.
