How To Breed SuperwormsWhen your superworms are at least 4 months old or 2 - 2 1/2" long, they are old enough to breed. Breeding superworms is a long term process, by the time you have food size worms again, it will have been about 3 - 4 months. If you have many mouths to feed, breeding superworms can be very economical.
The first thing you need is individual compartments to force the worms to pupate. Many people use film canisters, workshop screw/nail drawer units, or embroidery floss cases. Drill or melt a small hole in the top of each compartment, and add a small amount of oats to the bottom of each one.
You can start the breeding process with a minimum of 50 superworms. Starting with 50 superworms will eventually yield approx. 3000 superworms over several months.
Put one superworm in each compartment. Do not add any moisture source. Store the containers in a dark, warm (70 - 80 degrees) area. You will not need to feed them again until they become beetles.
Within 14 days, the worms will curl up, preparing to pupate. Any that are black and straight are dead and should be thrown away. Within another 14 days they become pupae. Once you notice pupa, you should check on them daily or so to watch for beetles.
In another 2 weeks or so, they become beetles. The beetles are white, then red, and finally turn black within 24 hours of becoming beetles.
Beetles should be removed to the breeding tank. A rubbermaid container makes a good beetle house. Drill holes in the lid for ventilation. Using the same substrate you would use for the worms, cover the bottom of the tank with substrate. Add several stacked egg crates for the beetles to lay eggs on and hide in.
The beetles will be very hungry and thirsty after their metamorphisis. Provide moisture using the same vegetables as you would with superworms.
The beetles do not need light, and seem to prefer darkness, but should be kept at 70 - 80 degrees to encourage breeding. In 7 - 14 days, there will be eggs within the egg crates and substrate, although you probably will not see them - they are very small.
Removing old food becomes tedious at this point because the eggs and baby superworms are too small to see and may be in the food. Throw old food into a seperate container and keep an eye out for small worms.
Every 2 weeks, remove all substrate to another container so the beetles won't eat the baby superworms. Add new substrate to the beetle container. You will need to do this every 2 weeks or so for 4 or 5 months.
Soon you will find many small worms in your worm tank. These will get full size within a few months when you can begin the cycle again.
