Growing superworms is not hard provided you begin with large worms, keep it dry and warm and provide food.
Forcing pupation.
This can be done in a manner of ways including isolating worms in 35mm film cannisters. I prefer the takle/sewing box approach!
Notice the tiny air holes ive melted.
You place the largest possible worm into each compartment or cannister. (this one is not quite big enough) . Next to it, is the beetle, called a 'darkling beetle'.
You place your worms without food in each compartment, no media is nessesary. You must keep them warm but dark. I use a heatcord inside a styrofoam box from the garden shed.
Im warmer months/climate this may not be nessesary.
After about 2-3 weeks, the turn into pupae, (see below) and days after pale beetles. They go dark in the coming days.
Once you have either pupae or beetles, place them in your tub of media,
on the surface.
provide raw carrot (moisture) and fresh greens (food) for the beetles, on the surface and use eggcratew for the beetles to hide and mate inside.
Never add water, mould will kill them, only change food off the surface.
watch greens remains for eggs, which the beetles will deposit on them and in your media. I prefer oats.
Provide plenty to eat and keep the tub warm. You will see nothing but beetles for some weeks. Eggs hatch within 2 weeks and you will begin to see tiny worms. Be patient.
Dont change the media, you may throw out almost invisible eggs.
So keep it cleanand dry as possible.
After 2-3 months, your worms will be growing rapidly. Need more? Repeat the process!
