Sorry for the misunderstanding. I was referring for the cab to be used indoors. I could never afford to use it outdoors. I have it everywhere in my house except the ferrets' room. It is in places that are generally safe from the ferrets. It is the scent that detracts the mice. It is better than the glue traps I used and I won't use poison. Mice were destroying everything for me. This is the safest and most effective thing I found yet. There is no product that is perfect without some draw back but this one is the closest I have come.
