Mice!!

[David.H]

As I'm sure you'll know, mice can apparently squeeze through a gap the size of a pencil. If it were me I'd attempt to seal up any pencil sized cracks / holes in the walls / window and door frames / roof etc. Doors themselves can be a problem, but depending on the type of doors fitted, small section hardwood battens running the width of the doors fixed to the floor inside or outside of the doors should prevent the mice gaining access under the doors. If all else fails and you have an electricity supply to the garage / shed / attic space, buy one of these ultrasonic / electromagnetic plug in mouse repellers - one unit covers an area of 232 square metres. I accept that living out in the country poses much more of a challenge. Fortunately I have a brick cavity walled garage so the only possible access points are the front door and side sliding door.

We suffer from squirrels or maybe rats as the heater plenum chamber of the modern (well 1998) car has been filled up with dog food pellets (1cm square) and/ or peanuts from bird feeders. Also air intakes & filters, both inside a garage, although the door is often left open. The wiring harness cover fabric & bulkhead insulation was also nibbled from a 4 year old Mercedes parked outside.
They haven't attacked the Seven ....yet!
