How do you raise mealworms?


Quick Answer

Mealworms are relatively easy to raise in a plastic container, such as a storage container or plastic box, with a sterile bedding of whole oats, chick feed or wheat bran. Feed mealworms various fresh fruits and vegetables. Sterilization of the bedding is very important as pests, such as grain beetles, may be hiding and could potentially harm the larvae. Sterilize the bedding in the oven on a cookie sheet at 130 to 150 degrees Fahrenheit.

After the bedding cools, spread it evenly around the container, and add pieces of fruit or vegetables. Ideal foods are those that contain some moisture but are not watery, such as carrots, apples and potatoes. Bedding may need frequent replacing as it is consumed by the worms. Harvest worms when they grow to the size that you need, and leave any that have already begun to pupate to become adults and breed the next generation. Place a screen over the farm to keep adult beetles from flying away.

Mealworms are the larvae of the darkling beetle and are common all over the world. In the wild, they are considered a pest, as they often feed on cultivated grains such as wheat and oats. They are also a favorite food for many animals, including poultry, wild birds and even some small, insect-eating mammals.
