If you’ve spotted tiny white worms in your compost bin, don’t worry—they’re called pot worms, or Enchytraeidae, and they’re harmless.
Pot worms often appear in compost bins when conditions are very acidic or moist, as they thrive in these environments. To reduce their numbers, try balancing the bin’s acidity by adding some crushed eggshells, which help neutralize the pH. Additionally, ensure your bin isn’t too wet by adding dry materials like shredded paper or cardboard.
Pot worms don’t harm the composting process, but keeping their numbers in check can help maintain a balanced ecosystem in your vermicomposting bin.
