Bait machine

Red or manure worms are kept in stock within a growing medium, and oftentimes the machines have a small reservoir in them to simulate rain and to feed the worms a nutrient solution. Electrical pulses are used to encourage the worms to come closer to the surface to obtain the nutrient solution. In connection with heating and constant high humidity, worms attain higher reproduction rates and faster growth.^{[citation needed]}
