SuperWorm Breeding

Breeding superworms isn't difficult, but it is slow going in the beginning and a little time consuming. If you're sick of buying them though, it's well worth the effort. Especially if you're like me and have several animals that eat them.


What you will need:

Plastic tackle box with dividers or small containers
Wheat or oat bran
Egg crate or TP tubes
2 small plastic totes or stackable containers

Superworms don’t pupate well (or at all) if you don’t separate them from other worms. The best way I’ve found to do this is a plastic tackle box. I drilled a hole above each compartment for airflow. It’s easy to do with a hot metal skewer. You can also use small containers like film canisters. Don’t add any food.


They seem to pupate better and have less die off when kept in a cool, dark location. I put mine in a cabinet in the basement. It stays between 60-70f. It takes a week or 2 before you'll see pupae. You'll know they're getting close when they curl up into a "C".


Once they pupate, they will look like "aliens" you can then move them to another container together and refill your separation box.

When they are about to turn into beetles, their eyes & legs will get darker like the pupae in the picture on the right compared to the picture on the left.

Going from pupae to beetle takes about 2 weeks. Keep them warmer and they will turn a little sooner. I keep my container on the top of an enclosure next to a ceramic heat emitter. Room temp at about 70F works pretty well too.


Beetles will hatch out cream colored and within hours will turn a dark brown, and by the next day will be black.


Here's how I set up my bins:

I used a 3 drawer plastic drawer unit. Drill small holes in the bottom of the top bin only. Put about an inch of wheat or oat bran in each drawer. Oatmeal will mold quickly and in general doesn't work as well. Put egg cartons or TP tubes in the top bin. The baby worms will hatch and crawl through the holes to the next bin. If you leave the baby worms with no escape, the beetles will eat them. Look for motion in the bran, they are TINY. I use the bottom bin for adult worms to feed off.


In the drawer with the beetles, keep hard veggies that don't stay wet. I use carrots, potato, and stems from the greens I use for salads. They will lay eggs on the veggies, so leave them in the drawer even after they dry up. In the other 2 bins feed a good gutload avoiding fruit and wet veggies as they will mold quickly and you'll have to change the bran out too often

Beetles will stop laying eggs and die off after a few months, that's why it's important to keep worms pupating or you'll have to start over.
