How long do fishing worms last?

Fishing worms, such as nightcrawlers and red wigglers, can last several days to weeks if stored properly. They thrive in a cool, moist environment and can survive longer if kept in a refrigerator or a damp container with bedding material. However, their lifespan can be significantly reduced if exposed to extreme temperatures or dryness. It's best to use them within a week or so for optimal effectiveness while fishing.
