Does shaving get rid of crabs?

No it doesn't. Think of how small a crab is, they ARE visible, but think again of how small their clamps are. When you shave there is always a stubble. It is never babies bottom SMOOTH. They can still hang on to those little stubble. The best remedy I was ever told of that is very inexpensive is Kerosene. Put it on for 10 minutes wash it off do it again wash it off. No more crabs!
