My boyfriend is quite hairy and has discovered dozens of fleas in his leg hair in the past couple days. I’ve herd that fleas only stay on human for a short while, but my boyfriend must be the exception. His legs are absolutly covered in bloody flea bites. He’ll take a bath to drown them all only to find they’re back on his legs the next day. We released a fogger or “bug bomb” indended to kill fleas in our house yesterday but this morning, he woke up and had dozens more in his leg hair. The strange thing is that I’ve only found a few on me and they don’t seem to bite me at all. He shaved his legs this morning hoping to reduce the problem. Is there any products out there for humans to protect against fleas? Any tips on killing them?
