Do mealworms prefer wet or dry environments?
The mealworm’s preferred environment is very dry, moderately warm, and dark. A bit of apple provides extra moisture for the mealworms and seems to stimulate rapid growth. As the temperature increases, so does the rate at which mealworms advance through their life cycle.
What conditions do mealworms prefer?
The mealworm prefers a warm habitat. When raising mealworms, keeping them in a warm habitat (77 to 81 degrees F) will cause them to grow much faster than in a cool or cold environment.
How much moisture do mealworms need?
For best results, keep the container around 80ºF and around 70% relative humidity. Mealworms do reproduce in temperatures ranging from 65-100ºF, but temperatures that range too high or too low can negatively impact growth and development.
Why do mealworms need moisture?

How long does it take for a mealworm to turn into a beetle?

What is the lifespan of a mealworm?
about 1 year
Why are my mealworms dying?
When pupae die and turn black, it’s usually because the worms weren’t given enough moisture with carrots or potatoes at the end of the larval stage. They need to store the moisture to last through pupation and will dehydrate and die if they didn’t get enough. They are also very heat sensitive.
What temperature should mealworms be kept at?
