- Worms only eat organic material, not plastic or cardboard.
- It is common for worms to eat scraps of food we might throw away, including fallen leaves from your yard, dead insects and even newspaper.
Worms will eat the following food items:
- Fruit and vegetable scraps. Worms will eat fruit and vegetable scraps, including things like potatoes, carrots, apples or other fruits and vegetables you want to compost.
- Egg shells: You should crush eggshells before adding them to the bin to make it easier for your worms to digest them. If you’re not sure whether your worms can handle a particular type of food waste like an eggshell, try crushing it first before adding it in!
- Tea leaves: If you have used tea leaves that are still damp from brewing a cup of tea (or even just steeping), just toss those into your worm bin as well! The same goes for coffee grounds (which are also quite acidic). These will be good sources of food for your worms while they help degrade the paper products in your kitchen scraps bin.
Fruit and vegetable scraps
Fruit and vegetable scraps can be added to the compost bin, worm bin, and vermicompost. Fruit and vegetable scrapes can also be used as food for your worms in a wormery or even inside their home if you have one!
Egg shells are a great source of calcium for worms. They also provide them with protein, minerals, fiber and vitamins. The egg shell contains the same amount of calcium as milk and also has more protein than an egg yolk. It is important to provide your worm bin with adequate sources of these nutrients so that it can function properly.
Egg shells are also a good source of vitamins including vitamin A (as beta-carotene), Vitamin D3 and E which help in immune system health as well as growth and development throughout life stages from childhood through adulthood into old age.
Tea leaves, tea bags and coffee grounds
Tea leaves, tea bags and coffee grounds are all good for worm farms. Coffee grounds are not good for worm farms. Tea leaves are not good for worm farms.
Crushed egg shells
You can also add crushed egg shells to your worm composting bin. The high levels of calcium and protein found in eggshells will provide a good source of nutrients for any worms that are present in the composting material. However, if you are using layers of shredded newspaper as bedding, crushed eggshells may not be necessary because they do not absorb much moisture and therefore will not help to maintain the moisture content of your layer.
Shredded paper such as newspaper or junk mail. Don’t use colored paper, magazines or glossy paper.

They also like some types of cardboard – e.g. cereal boxes and egg cartons (with no wax coating).
You may be surprised at just how much cardboard worms like to eat. They also like some types of cardboard – e.g. cereal boxes and egg cartons (with no wax coating).
Cardboard is a good source of food for worms, because it’s made from wood pulp. Cardboard that can be recycled or composted should be used instead of regular paper products, because they will break down more quickly in the environment and won’t add to your landfills’ carbon footprint.
Straw/hay (no seeds)
Hay is an excellent food source for worms. It’s easier to find than leaves and can be used in a variety of ways. Hay that has not been treated with chemicals or fertilizers will help the worms flourish, while also providing them with added nutrition. This helps the environment by reducing your need to purchase fertilizer and pesticides, as well as making sure your soil retains its natural balance.
Here are some ideas on how to get started using hay in your worm bin:
- Empty any existing bedding from your bin (this can be done by simply turning it upside down)
- Add fresh, pesticide-free hay until it rises above the level of your existing bedding by at least an inch or so (if you’re starting from scratch this may take several trips outside). Note: If you’re unsure about what types of hay are safe for use in worm bins, contact local farmers; many times they will be more than happy to give away their excess output!
Worms do not eat plastic or cardboard.
To keep worms healthy, feed them:
- fruit and vegetable scraps. Try to avoid using bananas, pineapple and citrus fruits as they can cause health problems for your worm farm.
- egg shells. This is a great source of calcium for your worms.
- tea leaves, bags & grounds used in making coffee/tea; crushed egg shells; shredded paper such as newspaper or junk mail (but not colored paper such as comics). If you have the time to shred the paper yourself it will help break down more quickly than a whole sheet of paper which has been folded into 4 or 5 pages before being thrown away by someone else who didn’t think it was important enough! Don’t use glossy pages however because these last longer than normal ones so there’s no point crushing up something that takes longer than necessary!
