What Do Red Wigglers Prefer to Eat?

Red Wiggler composting worms, also known as Eisenia fetida, are one of the most popular species of worms used for vermicomposting, the process of composting with the help of worms. They are voracious eaters and can process a large amount of organic waste, making them ideal for converting kitchen scraps and yard waste into rich, nutrient-dense compost.

So, what do red wigglers prefer to eat? Here are some of the best foods for these composting worms:

  1. Fruit and vegetable scraps: This is the most common type of food for red wigglers. They love fresh produce such as apples, carrots, lettuce, and potatoes. Avoid feeding them citrus fruits, as they are acidic and can harm the worms.
  2. Coffee grounds and filters: Red wigglers love coffee, as it contains high levels of nitrogen, which is essential for their growth and reproduction.
  3. Eggshells: Crushed eggshells provide a good source of calcium for the worms, which helps maintain the pH levels of their composting bin.
  4. Shredded paper and cardboard: These materials provide a good source of carbon, which helps balance the nitrogen levels in the compost. Just make sure to avoid glossy or coated paper, as they contain harmful chemicals.
  5. Bedding material: Red wigglers need a soft, moist environment to live in, and bedding materials such as shredded newspaper, coconut coir, or peat moss can provide the perfect home for them.

It’s important to note that red wigglers should be fed in moderation, as overfeeding can lead to anaerobic conditions in the compost bin, which can harm the worms and lead to unpleasant odors. It’s best to feed the worms small amounts of food every few days and to make sure that the compost bin remains moist and aerated.

In summary, red wigglers are easy to care for and are excellent at breaking down organic waste into compost. They prefer a balanced diet of fruit and vegetable scraps, coffee grounds, eggshells, shredded paper, and bedding material. Just remember to feed them in moderation and to keep their compost bin moist and aerated for optimal conditions.
