Why do fleas bite some people but not others?
My dog as gotten fleas a couple times over the years he’s lived with us and I’ve never been bitten, despite sharing a bed with him. Meanwhile, my roommate’s legs become immediate targets for the fleas. Does he just have nicer legs?
The fleas that bite dogs and the fleas that bite humans are the same which is why the Black Death ravaged Europe in the middle ages. It was transmitted through fleas.
Anyway 2 things could be happening, the first is that you might be one of the rare humans who do not react to flea bites.
You may not be allergic to their numbing chemical.
The other is that you might not “taste” good. Like if you eat a ton of garlic fleas won’t bite. The same goes for dogs who eat tons of garlic, they rarely get fleas.
