MOUSE, Rodent Problem !!?

Be aware that the mice will not necessarily need a food source in the room to nest there. Or it may not be a nest - they may simply be 'commuting' through the room on the way from a food source to the nest. They are probably finding a way into cupboards and the like. Try putting food into plastic containers out of their reach. I know it's a pain, but so's having a mouse infestation! Keep an eye out for droppings for clues as to where to lay more traps. Look for 'choke points' - places where the mouse has only a few choices of routes to go through as a trap is more likely to be successful here. As for bait I would try something like cereal as it is closer to what mice would eat in the wild and they are more likely to trust it.
