There are plenty of places where you can get them: http://www.canadiannightcrawlers.com/ http://www.gollonbait.com/q/live-bai...n-nightcrawler and http://www.bestbait.com/Canadian-Nig...FLAT-NIGHT.htm just to name a few. They should be fine for a month, you could ask here or on our sister forum Caudata.org, but yet again, I don't know if they last that long, because all my animals ate them before I had a chance to test how long they'd survive
