Mice can squeeze through a gap of just 6mm (0.25"). Fix MouseMesh screens over existing airbricks to stop mice from getting into your home. Not only do MouseMesh screens prevent mouse damage to your home, they are extremely humane as mice are not being killed but simply deterred.
MouseMesh has been endorsed by PETA (People for the Ethical Treatment of Animals) an organisation that has described MouseMesh as the 'Best Humane Wildlife Innovation of 2007'.
Attach the MouseMesh to the airbrick applying a glue such as Avifix to the back of the sceeens or fix with screws through the MouseMesh into the airbrick.
