after the fifth day , we noticed a mouse that would pop out from under the refirgirator , moves very fast then goes back to where it came from . then for the next 11 days i kept complaining about the mouse . however they kept sending me an incompetent person who kept changing the trap location from under the frig, to washing machine to under the sink. with no results , i think the mouse was smart , that wouldn't even come close to the mouse traps.
