Good N' Lively Worm Bedding is the ideal habitat and food source for crawlers. Simply add non-chlorinated water, mix and add worms. Refill or replace bedding to replenish food supply in Crawler Cribs after six weeks (depending on number of crawlers). Premixed Good N' Lively Worm Bedding comes in a handy transport container - pour as much or as little as you need and seal. Also doubles as a temporary worm storage container - open flap on lid to let air in to crawlers.
