Nightcrawlers are one of the most popular fishing baits available. Fishermen have used them to catch everything from largemouth bass and channel catfish to hybrid bluegill. Our nightcrawlers attain lengths of up to 14" and if kept properly, can live 6-8 years. They come in a styrofoam box and should be kept at a temperature of 35-40 degrees Fahrenheit. Each box contains one dozen nightcrawlers.
