We have tried for five years to provide two nesting sites for the Black Rat Snake as it was known then. I see lots of baby rat snakes but they are doing well not because of my nesting boxes - at least not yet. The adult snakes I see are using their own nesting sites and that is apparently working well for them. The Eastern Rat Snake as it is now known, is safe on our property at Singleton Lake. I often see them weaving their way along the edge of the buildings. I showed this one to the grand kids. The snakes calm down after they realize I mean them no harm... plus they are quite harmless.
