I too started a "culture" if you will, of the mealworms, last year during the crisis. I bought a tub of 50 for 2.50 or so, put them in an old container with bran and a piece of scratch paper to cover, and managed to remember to add a rotten apple slice, apple core or green potato half every so often ( every two weeks?). Pretty quickly I had two beetles in there, and dead worms. Nothing much visible for months, but now I have thousands of worms !
They have begun the process of changing to beetles again, so I have quite a few larvae now. If I had known they were so temperature dependent (much warmer now of course) I might have hung a light nearby to speed the process, but if you start now instead of October like me, you should have a quicker time of it.
I finally added the rest of the bag of bran I bought last year. Amazing how little care these require!
