found two dead in our house after we moved out of the basement after our construction project finished. they had the run of the basement for a couple of months before we realized what was going on and tried to restrict access in/out and remove food/water sources.
i am so paranoid it wasn't just two, but i don't believe i've seen more droppings after finding the second one dead.
what traps do people set? and sadly it looks like the balsam fir repellent doesn't actually work out in the open but does it if you put it in the superstructure?
Put this stuff at the corners of your garage door and you won't have any more mice in the garage. Works great.
