Home made live trap
You can make your own live mouse trap by using a milk bottle, preferably one with very curved sides. Place the bottle parallel to the wall at a 45 degree angle using a cardboard box or similar for support and construct a ramp leading up to the neck of the bottle, this may be made of cardboard, wood or whatever you have to hand.
