I raise mostly my own silkworms from eggs (I harvested from my own silkworms), I use 4.5 ClearVue tub which has a lid I punched holes in using a soldering iron.
I use mainly fresh mulberry leaves to feed them - I buy the leaves from people on GumTree.
Superworms - I keep 50 - 100 in a 4.5L ClearVue tub (with a lid I made holes in as above) with about 1L of wheatbran or a mix of wheatbran and oat bran + some carrot chunks and the whites from buk choi to give moisture.
Mealworms - I keep these in a 1.5L ClearVue tub about 1/3 full of wheatbran , I add carrot to provide moisture and they also get stale adult beardie pellets from the crickets.
Crickets , I keep these in old cleaned Piscus cricket tubs (pays to hang onto these , very handy to keep all sorts of things in) , I buy the crickets 500 - 1000 at time , was 1000 per 2 - 3 weeks til recently when my boy unexpected and suddenly died (organ failure due to a birth defect ?).
I put maybe 80 cricket into each tub with maybe 10 RepCal Adult Beardie Pellets (dry from the bottle) and add a chunk of carrot to give them a source of moisture.
I can keep them crickets happy and alive for about 3 -4 weeks. If you are buying in bulk, buy one or two sizes smaller than you need and they will grow and not all die off of old age before you get to use them.
So in my case as all my pet lizards are adults , I buy 2/3 size or medium size crickets in my bulk orders.
BSF lavae, not used very often , all my lizards are too big except my water skink who doesn't seem to like them - she's too well fed and too fussy. Leave them in the bedding and simply fish out the lavae as needed by hand.
