Feeding and Maintaining Your Worms


Worms like to eat many of the same things we eat, only they aren’t as picky. Stale bread, apple cores, lettuce trimmings, coffee grounds, and non-greasy leftovers are just some of the foods we usually discard that worms love.

Do Feed Worms

  • Vegetable scraps
  • Fruit scaps and peels (mold/rot is fine)
  • Bread and grains
  • Teabags
  • Non-greasy leftovers
  • Napkins, paper towels

Don't Feed Worms

  • Don't overfeed citrus - should be no more than 1/5 of worm food
  • Meats, fish
  • Greasy foods
  • Dairy products
  • Twigs and branches
  • Dog/cat feces, cat litter

Begin feeding your worms only a little at a time.  As they multiply, you can add larger quantities of food scraps.  After a few months you can feed about a quart of food scraps per square foot of surface area each week.  To avoid fruit flies and odors, bury food under top layer of the bedding.  Don't dump and run!

Worms prefer smaller-sized scraps and will eat through them more quickly than large or whole pieces of food.  

If your worm bin starts to smell bad, it could be a sign that you are adding more food than the worms can process.  If too much food is added, it can even heat up and kill the worms!  Quit feeding for awhile and when most of the food has been eaten, start feeding again.

Add fresh bedding every 1-3 months

Always keep a one-inch layer of fresh bedding over the worms and food in your bin.  Shredded newspaper works great!

Keep bedding as moist as a wrung out sponge

In a plastic bin, add dry bedding to absorb excess moisture.  You may need to sprinkle the contents of wooden bins to moisten them occasionally.
