You’re warm. You’re salty. You’re basically a walking snack bar. Bugs are drawn to carbon dioxide and sweat. Your skin is like a five-star resort for them.
Microscopic Black Bugs On Skin
That little black bug on your arm? It probably fell from a tree. Or your cat. Or your bag of potting soil. They’re clumsy, not evil.
One study found that the average human has 1.5 million microscopic creatures living on them at any time. That’s more than the population of a small country. Your skin is a country. A very small, very weird one.
The Drama of the Dot
We humans love a good drama. A single black speck on your skin is a mystery. Is it a tick? A bed bug? A tiny alien scout? Our brains fill in the scary gaps.
But here’s a fun thought: most of these bugs can’t hurt you. They don’t have mouths big enough to bite. They’re like little black jokes your skin tells you.
Ever seen a thrips insect? They look like black thread clippings with wings. They eat plants, not people. If one lands on you, it’s probably lost. “Oops, wrong planet.”
