This Eastern Milk Snake was caught on a glueboard in a Connecticut basement.  These snakes are harmless to humans.  They feed on insects and when large enough, rodents.  This is sometimes confused for the Copperhead snake but subtly differences indicate it is not.  Such as the checkerboard colored belly and the head that seams to blend into the body (not triangular).  This beautiful specimen was removed using olive oil spray.   The oil breaks down the glue and makes freeing the snake possible.  It works very well!
