I will in the future when my Nerodia are big enough to breed. Otherwise I wouldn't brumate unless the snake senses it's winter and starts to go off feed. I'm sure some of the more southerly Nerodia will breed without brumation but it never hurts (as long as the snakes are healthy). I do plan on brumating my trio of Bluestripe Garters for about 6 weeks. Hopefully I'll get a bunch of little blue babies next year!
