Mice don't like cedar chips? Good to know.
I'll add that to my list of "why I love cedar chips".
My list so far:
Natural insect deterrent
Smells awesome
Cheap
Easy to transport
Easy to rake and scoop up
Can be reused as mulch around my trees and bushes
We've got an 8' x 20' coop with one open wall, and the floor has always been cedar chips, about 3 bags covers it. When it gets icky, I scoop shovel it into a wheel barrow and spread it under my trees. I can also throw another layer on it, if the weather isn't conducive to shoveling it out.
Note...Every place I use cedar chips is very airy, so I don't worry about fumes. I used to have pet rats, and it's a big no-no with them, because their cages are often more closed.
Oh, wait...we had mice like crazy in our coop. I'm guessing mice aren't all that opposed to cedar chips.
Bummer. I was doing a search for mice, as in: "how to control them". I'll keep searching.
