Excess feeding will sour, creating acid conditions and attract several kinds of undesirable mites, insects, etc. Mites Small, brown mites occasionally infest worm beds by the millions. These mites can become so populated that most of the food is eaten in one night. After wetting the bed, mites swarm to the surface, often covering the entire bed.
Red mites are parasites that suck earthworm blood while they are attached.
They also pierce and suck fluid from earthworm egg capsules. Mites, insects and other pests will move to the top of the bed. Repeat procedure every two to three days if needed. Earthworms are not damaged. Place watermelon or cantaloupe rind or potato slices on the bed.
