The Truth About Worm Diets
Worms eat organic matter — things that were once alive. They pull decaying leaves, vegetable scraps, and bacteria-covered particles into their mouths (which is that tiny opening at the very front of their body) and run it through their digestive system.
💡 Did You Know? Worms don't actually eat the food directly. First, bacteria break it down slightly, then the worm eats the bacteria-covered particles. Worms are farming bacteria — just like we're farming worms!
What We Feed Our Worms at BuBi Worms
- 🥕 Vegetable scraps — carrot peels, lettuce, zucchini (favorites!)
- ☕ Coffee grounds — worms go absolutely wild for these
- 🍌 Banana peels — high in potassium, very popular
- 📰 Shredded cardboard — provides carbon balance
- 🍂 Dead leaves — classic worm food
What You Should NEVER Feed Worms
- ❌ Meat or fish — attracts pests and smells terrible
- ❌ Citrus peels — too acidic, can kill worms
- ❌ Onions and garlic — worms hate the smell
- ❌ Dairy products — same problem as meat
- ❌ Salty or spicy food — dehydrates them
The Funny Experiment We Did
Burak once put a tiny piece of pizza crust in with our worms to see what would happen. Three days later: gone. The worms went for the crust before the fresh banana peel. We now know worms have surprisingly good taste.
How Much Should You Feed?
A good rule: feed your worms about half their body weight per day. Our main bin has about 2 pounds of worms, so we add about 1 pound of scraps every day or two. Don't overfeed — leftover rotting food causes bad smells and fruit flies.
