How does the "target" knows who's using mones?

This has been covered many times

There are several different factors. Silage, pinpointing, vapor trails and congruence. But its basically the same way we pinpoint sound or light. On an instinctual primal level we all understand chemical communication. Its how we communicated in the womb. The question is kinda like asking how does your body know how to stay alive. How does your heart know how to beat ? No one taught it. It just knows, its instinctual.
