Thanks for the info guys. We were clearing the land because no one has been living there for several years. We want to make a clear path to the stream for the dogs, so we cut down some trees (mostly birch and oak trees). I was just making sure that on the off chance some were pine or cedar that it wouldn't harm the snakes. That's the LAST thing I want.

I had just remembered that some one on here had a friend watch their house and they burnt an unidentified substance in their home, killing a few of their Balls. I think I should install a fan to keep on while the stove is going, just in case.
