Have just started breeding locusts and my first batch hatched last week and more this week. Much easier than I thought. I keep the adults in a small Exo Terra terrarium with a light and heat mat I had spare and some damp sand. Got about 200 babies so far. Transferred them to a cheap plastic herp tank which I stuck mesh on the lid. Now using the small cheap plastic herp tanks to put the sand in so I can just stick a lid on when babies are incubating and hatching.
