Tips for Success

💡
Pro TipMealworm farming is very low-maintenance — check every few days, top up bran and moisture as needed.
💡
Pro TipSift substrate through different mesh sizes to separate larvae by size.
Common Problems & Warnings
⚠️
WarningMealworms have poor nutritional value (high fat, low calcium, high chitin) — always supplement with calcium dust.
⚠️
WarningBeetle frass can cause allergic reactions in some people — wear a dust mask when sifting.
⚠️
WarningNever use mealworms as a staple diet. They are a treat feeder only.
