If you have an incubator it works best but there are other ways to keep them warm, heating pads , heating tape etc... I use a hovabator that I got from LLLreptile for like 40 bucks I put like 20 adult crickets or so in a plastic Tupperware with a smaller Tupperware inside filled with very moist organic potting soil, put some dry gut load and water crystals in there and a piece of egg carton. Put them in the incubator for 5 or 6 days @between 86 and 92 degrees, make sure to open the top every so often for ventilation. Then after five days, take out the adults and leave the soil and food and crystals. Within two weeks you should have a bunch of pinheads that you can then transfer to a larger rubbermaid with holes cut out and aluminum screen hot glued on for ventilation. If you have any questions you can pm me, I also have been working on dub, hornworms and silkies.
