I may not be the resident expert in Atlanta on how to get rid of crabs, that title belongs to @hotdog. He's always getting crabs. The good, the bad, and the ugly kind of crabs. He gets them so much, that I've been able to glean enough information to almost become an expert in ridding them. I only have expertise in theory though, not in practice. For practical expertise, again, you will need to reach out to @hotdog. Honestly, you shouldn't even be reading my post. Just search for hotdog's as it will be a more accurate representation of his advice. Go straight to the source. Do not pass go. Do not collect $100. Skip the middle man. Unless he has a PT pass as a GM, then I guess I can give you the advice. So, here it is...
The first line of defense is to avoid getting them all together by using protection. If that doesn't work, then seek help from a doctor who will likely supply you with a shampoo or ointment.
