Ya I've found its almost impossible to rid them quicker then they reformulated. Anything that works they soon get wise to so.....Yeah she did! Apparently she learned it in Hawaii and became very skilled at it.

I guess before I go to shoveling rats I should hit the arcade and brush up on my Whack A Mole skills.
