I have recently had mice in my house.. my cats smell it out (usually in the middle of the night) and they manage to wear it down enough for me to swat it with a broom.. I've killed 2 . I just hope thats all I have but just in case I put out poison under my counter and also I am doing to use the peppermint oil trick .. besides seeing them in the middle of night, I see droppings in 2 of my drawers.. yuk yuk yuk. I have NEVER had mice before and I can't figure out why all of a sudden they are coming in
