Maggots are the larvae of flies and usually gain access via eggs laid on the food scraps you put in. The first step is to ensure flies can’t lay eggs in your kitchen caddy or where you store the waste before you compost it. They can be a sign that the conditions in your wormery are suitable for fly larvae to thrive and that the organic matter in the bin is rotting rather than the worms eating and composting it. Maggots are not harmful to the worms and can even be a valuable food source for them. However, if you find the population of maggots to be excessive, you can try reducing the amount of food scraps you add to the wormery or covering the bin with a lid to reduce the number of flies that can lay eggs in it.
