Is there any way to tell if nits (lice eggs) are dead or alive?

There is no way to look at a nit with the naked eye and determine if it is dead or alive. And although some people claim it does, popping them does not prove that one way or the other either. They are just too small. The only proof is when they don’t hatch 7-10 days later.  Therefore, the best practice is to remove them from the hair.
