I know where I live in New England mouse guards should be on 1st of September this year. I would be looking for mice this year before put they on. In the middle of August we had about 4 days in the morning where it was about 45 degrees or so :shock: that's when mice go in. Now make sure you do not trap a mouse inside before you put on the mouse guards.
