Mealworm Tray Setup Guide for Beginners
Setting up trays correctly is one of the most important parts of mealworm farming. A proper tray system improves growth, reduces smell, and keeps the colony healthy. This guide explains the full process step by step. If you’re unsure how to begin from the very basics, check out our How to Start Mealworm Farming guide to get a complete overview before setting up your trays.
1. Choosing the Right Trays
The ideal tray should be:
- Food-grade plastic
- 3 to 4 inches deep
- Smooth inner walls
- Light-colored (easy to inspect)
Avoid cardboard or wooden trays because they absorb moisture.
2. Preparing the Base Layer
Fill the tray with a clean, even layer of wheat bran.
- Recommended depth: 1.5 to 2 inches
- Do not overfill
- Spread bran smoothly for better airflow
This acts as both feed and bedding.
3. Adding Mealworms
The right quantity helps maintain temperature and growth.
- 5,000 to 7,000 larvae per tray
or - 1 kg worms in 2 kg bran
Too many worms cause heat build up. Too few worms slow growth.

4. Moisture Feed Placement
Moisture feed should be placed carefully to prevent fungal issues.
Best options:
- Carrots
- Potatoes
- Pumpkin slices
Place moisture food in the corners. Replace every 2–3 days.
5. Airflow and Covering
Trays should have good ventilation.
- Cover with mesh cloth or breathable fabric
- Do not use an airtight lid
- Keep trays in a dry, dust-free room
Good airflow reduces smell and prevents mold.
6. Stacking the Trays
Stacking saves space and keeps the farm organized.
- Maintain 1–2 inch gap between trays
- Use racks if available
- Do not stack too tightly
Proper spacing allows air to circulate and prevents overheating.
7. Cleaning Cycle
Clean trays regularly to maintain colony health.
- Clean every 12–15 days
- Sift out frass (waste)
- Move worms into fresh bran
- Wipe trays dry before reusing
Clean farming reduces mortality and improves production.
Conclusion
A well-designed tray system ensures faster growth, fewer problems, and steady production. Whether you’re a beginner or scaling your farm, these simple tray setup steps help your mealworm colony stay healthy and productive.
