Big hole in garage ceiling, laughing field mice. Help!
We just bought our first house and in our excitement, we overlooked, many, many things, including this gaping hole in the ceiling of the garage, through which many country field mice have scurried into the kitchen, walls, wherever. Our cat gets as many as she can, and we do trap, but I'm still seeing them. Obviously I need to patch up this hole ASAP. But how in the world would I do it around all those pipes? What materials would I use? How would I get it tight enough so the mice can't squeeze through?
As far as DIY goes, I'm about a 7 in confidence and 4 in ability.
