Worm composting is usually smooth sailing, but even the most seasoned worm keepers run into the occasional hiccup. Whether your worms are staging a great escape or your bin smells like a middle school gym locker, don’t worry—every problem has a solution.
This guide dives into the most common worm bin issues and how to fix them, so you can get back to being a composting superstar.
Problem 1: Worms Escaping the Bin
Few things are more unsettling than seeing your worms making a break for freedom. Escaping worms are usually a sign something’s wrong in their environment.
Causes:
- Bedding is too wet or dry.
- The bin is too hot or cold.
- Poor ventilation.
Solutions:
- Check moisture levels—bedding should feel like a wrung-out sponge.
- Ensure proper ventilation by fluffing the bedding or clearing air holes.
- Move the bin to a location with a stable temperature (55–77°F is ideal).
Problem 2: Bin Smells Bad
A healthy worm bin should smell earthy, like fresh soil. If it stinks, something’s out of balance.
Causes:
- Overfeeding leads to rotting food.
- Poor airflow promotes anaerobic bacteria.
- Excess moisture creates a swampy environment.
Solutions:
- Remove uneaten food and feed worms smaller portions.
- Add dry bedding to soak up excess moisture.
- Fluff the bedding to improve airflow.

Problem 3: Fruit Flies or Other Pests
Unwanted critters in your worm bin? While a few bugs are normal, an infestation is not.
Causes:
- Food scraps left uncovered.
- Excess moisture or rotting food.
- Bin location attracts pests.
Solutions:
- Always bury food scraps under bedding.
- Add dry bedding to reduce moisture.
- Use a breathable lid or cover to discourage flies.
Problem 4: Worms Aren’t Eating
If your worms aren’t chowing down, they’re probably stressed—or full.
Causes:
- Overfeeding leads to uneaten food buildup.
- The wrong types of food (e.g., citrus, salty scraps).
- Environmental stress (temperature, moisture).
Solutions:
- Stop feeding for a week to let worms catch up.
- Avoid problematic foods. Check What You Can and Can’t Compost in a Worm Bin.
- Ensure proper temperature and moisture levels.
Problem 5: Bedding Too Wet or Dry
Worms need bedding that’s damp but not waterlogged. Too wet or too dry, and they’ll struggle to thrive.
Causes of Wet Bedding:
- Overwatering.
- Excess moisture from food scraps.
Solutions:
- Add dry bedding like shredded newspaper or cardboard.
- Check drainage holes to ensure liquid can escape.
Causes of Dry Bedding:
- Lack of moisture in the environment.
- Poor airflow.
Solutions:
- Mist the bedding with water (but don’t soak it).
- Cover the bin with a lid or damp cloth to retain moisture.
Problem 6: Mold in the Bin
A little mold is normal and harmless, but too much can indicate issues.
Causes:
- Overfeeding creates a food buildup.
- High humidity encourages mold growth.
Solutions:
- Remove moldy food scraps.
- Feed smaller portions and monitor moisture levels.
