We actually saved a family of mice this year. When I levelled the ground for the swimming pool, I made a heap of turf and soil. When moving late summer, 2 tiny mice tumbled out of a gap - blind and useless. I was going to leave them for the magpie, but Marcia wanted to guard them. Mouse appeared and saved them, carrying them into a hedge. We dug up 2 more later, one dead, another survived. So we did our it to increase the mouse population!?!?
Just heard on R4 about more rats this year, due to warmer winters extending breeding season. They are getting braver, and there have been cases of rats entering homes through letter boxes!
I need to seal my new air bricks... still lodged in place with stones etc. Was going to do it properly with mortar, but might just get the foam gun on it.
