How To Grow Your Own Mealworms
“The idea is to buy 500 (or more) worms in the beginning and be able to sustain the colony for several years,” Coogan says.
Cost for 1,000 mealworms online runs between $14 and $20 and a 10 by 20-in. clear plastic tub can sustain 1,000 to 5,000 mealworms. Coogan cuts a hole into the lid for adding table scraps daily, and covers it with a screen. Place the mealworms in a few inches of wheat bran, corn meal, bone meal, or commercial mealworm bedding.
The mealworm cycle is larvae-to-pupa-to beetles, which lay the eggs. Once the eggs are laid, Coogan suggests moving the beetles to another bin. A female beetle can lay as many as 500 eggs. Kept at 70-80 F degrees, the eggs hatch in 10 to 12 days, and the larvae grow to about an inch in about 10 weeks.
“The larvae stage is the typical stage that they are fed to chickens,” Coogan says. “A small handful (of mealworms) every day or two is fine.”
He uses mealworms to train his chickens and to reinforce behaviors like going in the coop at night.
Growing superworms takes longer - about 5 months to grow to 2 1/4 in. - and adult beetles need to be removed every two or three weeks to allow the eggs to hatch, as adults will eat the eggs.
Coogan suggests starting with 100 superworms (about $5) and placing worms in individual compartments of a clear grid jewelry organizer box. Cut a small breathing hole in each cell and place the container in a dark area for 10 days. Once they change into pupae, put them in a separate nursery container so beetles and larvae won’t eat them. After the pupae turn into beetles, put them in a breeder container and feed them as you would feed mealworms. After the beetles’ eggs hatch in about a week, move the beetles into another container, so that the larvae can grow into superworms. Repeat the cycle for a continuous supply. Besides feeding your own chickens, growing the worms can be a sideline business.
“There is a large pet reptile sector who are interested in growing mealworms and superworms. These people should not be overlooked if you are thinking about raising your own beetles for resale,” Coogan says.
“It’s fun to watch the life cycle of insects,” he adds. “It’s easy to raise them and easy to incorporate kids helping out in the husbandry tasks.”
