Dave Liquorice in the thread about a power failure alarm for a shed, mentioned using a baby alarm to listen for the mouse traps going off in his attic.
I do suspect that that is a leg-pull, but it did remind me that having got rid of this autumn's ingress of unwelcome guests from the local fields, it would be sensible after all these years here that I did something about making it a bit more difficult for the little blighters to get in.
There are something like 7 traditional (they were fitted in the late
1920's) cast iron vents round the cottage just above ground level. The grill gaps will be considerably greater than 7mm so don't really present much of a barrier.Any suggestions about some modification that wouldn't look too naff, but would reduce my need for the baby alarm !!
