What I was saying is this: any fool can catch a mole, and for that matter any fool can catch a mouse, or a rat, a squirrel, rabbit, fox etc etc. 
  
But how many fools can make a living at it? 
  
Just knowing how to, does not make the man, or make the man a real professional. 
  
Losing the odd bit of work to the part timers shouldn't hurt anyone too much, they are after all just amateurs who know a little bit.
