Hey everybody, I took the advice of JJThink and bought some Mouse Magic, which is a mouse deterrant made of peppermint oil, spearmint oil and another natural ingredient (not cedar). I just put the packets in my barn yesterday so don't have an update on how well it works, but my barn sure smells great!!! Since my barn has a dirt floor, I'm thinking of planting a few springs of peppermint in there and put some chicken wire in front of it to keep the birds off of it. Maybe it will help keep the snakes out too. What do you think about this idea???
