Canadian nightcrawlers are a great bait worm. As their name implies, the are mainly from Canada. We do not grow and breed Canadian Night Crawlers. They are too difficult to breed and raise in captivity but are easily harvested from fields in Canada.
There are people who harvest the big fat Canadian bait worm every year. The nightcrawlers are shipped in bulk to us and then we refrigerate the worms, break them down into smaller quantities and sell them cupped or in bulk. Canadian nightcrawlers are one of the best bait worms in the world.
Canadian night crawlers still provide an outstanding bait for catching the biggest fish.
