Pot worms or white worms are small, white, threadlike worms that are found in worm bins when there is a quantity of finished material. They are beneficial organisms that feed on decaying organic. While usually found when the bedding in the bin is slightly acidic, their presence does NOT indicate a pH problem and pH adjustment is not recommended. Pot worms are white, segmented worms, most often mistaken for baby redworms. If you look close enough, their bodies are nearly transparent and their digestive system quite visible when viewed through a hand lens. Potworms do not feed on living plants and pose no threat to the garden or people.
