Mealworm Feed Calculator Tool (Complete Guide)
Mealworms use wheat bran as their primary feed and bedding. Correct feed planning is one of the most important parts of successful mealworm farming, especially for beginners.
This feed calculator is designed to help you estimate monthly wheat bran requirements, plan storage, and control costs based on your farm size.
This tool does not give exact numbers. Instead, it provides safe working estimates that beginners can adjust with experience.
How Mealworms Consume Feed
Mealworms do not eat feed at a fixed rate every day. Feed consumption depends on:
Number of mealworms per tray
Growth stage (small larvae eat less, large larvae eat more)
Temperature and humidity
Cleanliness and moisture control
That is why planning feed monthly, not daily, works better.
Mealworm Feed Calculator: Plan Your Colony Growth
Managing your feed costs is the key to a profitable mealworm farm. Our custom calculator helps you estimate the exact amount of wheat bran (substrate) and moisture sources required based on your current tray count and larval density.
How to Use the Calculator:
Enter Tray Count: Input the total number of active trays in your rack system.
Select Larval Stage: Choose between young, mid-stage, or harvest-ready larvae.
Calculate: Get an instant estimation of weekly and monthly feed requirements.
Pro-Tip: Proper feeding prevents cannibalism and ensures maximum protein yield. Always maintain a 2:1 ratio of dry feed to moisture sources (like carrots or potatoes) for optimal growth.
Standard Feed Assumption Used in This Calculator
For learning purposes, this calculator assumes:
One standard tray consumes ~1.5 kg wheat bran per month
Tray depth: 3–4 inches
Normal stocking density
Temperature: 24–28°C
If your trays are overcrowded or too cold, feed usage may increase or decrease.
Monthly Wheat Bran Requirement (Reference Table)
| Number of Trays | Estimated Feed (kg / month) |
|---|---|
| 2 trays | ~3 kg |
| 4 trays | ~6 kg |
| 6 trays | ~9 kg |
| 8 trays | ~12 kg |
| 10 trays | ~15 kg |
| 15 trays | ~22–23 kg |
| 20 trays | ~30 kg |
This table helps beginners quickly understand how farm size affects feed needs.
Wheat Bran Cost Planning Worldwide
Wheat bran prices change by:
City
Season
Supplier (retailers or wholesaler)
Typical price range:
| Quantity | Estimated Price ($) |
|---|---|
| 5 kg | 1 – 2 |
| 10 kg | 3– 4 |
| 20 kg | 8 – 16 |
| 40 kg | 30 – 40 |
Buying in bulk usually reduces cost per kg.
Feed Storage and Handling Best Practices
Poor storage ruins feed quality and causes pests.
Follow these rules:
Store wheat bran in sealed plastic or cloth bags
Keep bags off the floor
Avoid damp rooms
Protect from ants and insects
Do not mix old damp bran with fresh bran
Always keep at least one extra month of feed ready.
Moisture Feeding and Its Effect on Feed Use
Mealworms do not drink water directly. Moisture comes from vegetables.
Recommended moisture sources:
Carrot
Potato
Cucumber (small quantity only)
Rules:
Add small pieces only
Remove within 24 hours
Never let bran become wet
Too much moisture increases mold and reduces feed efficiency.
Feed Usage by Farm Size (Practical Examples)
Small Home Setup
4 trays
Monthly feed: ~6 kg
Easy to manage
Ideal for beginners
Medium Growing Setup
10 trays
Monthly feed: ~15 kg
Requires better planning
Needs regular cleaning
Larger Setup
20 trays
Monthly feed: ~30 kg
Requires strict hygiene
Feed storage becomes important
Beginner Safety Disclaimer
This calculator is meant for planning only.
Feed usage may change due to:
Temperature fluctuations
Overcrowding
Growth stage differences
Poor moisture control
Always observe your trays and adjust feeding accordingly.
