A week ago in the evening my dog brought surrounded by from the garden a mouse. It likes to salt away away around the back of my living room, at the back the tv, video/dvd case and display cabinet. We hold tried to trap it humanely by getting a cat cage and putting cornflakes and syrup inside, it considered necessary to go surrounded by but when it sensed we were implicit it ran away again. We bought a humane mouse trap and put a piece of a chocolate hotel inside but it's very reluctant. We're really feed up of this now, will we enjoy to call an exterminator? How long could it shift without food/water and what could it be surviving on?
Answers:    Use peanut butter. Mice step nuts over it. Also, place the trap against a wall. Rodents travel close to the walls and are more likely to find their style into a trap that is placed within their path. Happy hunting!
Try a definite mouse trap. The pests life is not vital. That or borrow a friend's cat.
