Nightcrawlers

Canadian Nightcrawlers(Lumbricus terrestris) are prized by fisherman and used primarily for fish bait.  They are large worms, measuring up to 14 inches when fully extended.  These worms must be kept cool and they will not survive in temperatures above about 65 F.  Hence, they must be kept refrigerated and kept out of the hot sun. 

European Nightcrawlers(Eisenia Hortensis) are great for bait, composting, and recycling. They are tough, warm weather animals that do best when temperatures are between 60-70 F. European Nightcrawlers can grow very large, often exceeding 8". They are almost as prolific as African Nightcrawlers, are great composting worms, and produce wonderful organic fertilizer
(Worm castings).

Red Worms (Eisenia Foetida) are available for the traditionalists. For pricing, go to the order page and click nightcrawlers.
