How to breed and raise cockroaches. Because some people may have no idea how to keep roaches here is some general information over how to do it.
Gather a lot of deli containers. lol Put many needle sized holes on the deli container lid or cut out a chunk of the deli container lid and glue small screening (such as no-see-um screening) to cover the patch on on the lids for oxygen and ventilation. Get something like potting soil. Put a layer of potting soil of about 1cm deep or less in the deli container. Put a few pieces of bark that do not grow mold, and a few dried leaves. First test to see if the particular roaches you have do better in a semi moist or slightly dryer than that conditions. I have kept my roaches in the past too moist and so they did not do well. Keep the substrate just a little moist to a little dry on the surface on the substrate (some species of roaches though may need to stay moister than this). Feed them bread or other stuff. There should be some foods to avoid like coconut oil (I have read that it is toxic to roaches) and things with pesticides. Store the deli containers with roaches in a shady spot where the sunlight does not shine on the roach deli containers because sunlight will heat up the deli containers until it gets too hot for the roaches and so the roaches roast to become BBQ. lol I do not know of much else you need to do. Some roaches have less tolerance for extreme heat than others, for example Byrsotria sp. "Cuba" cannot withstand some hot temperatures that other roaches like Turkestan roaches and Pycnoscelus femapterus can live through.
Keep the oothecae like the roaches. Probably for most species slightly moist conditions is best for oothecae, but that possibly is not true for some species, like desert Arenivaga possibly will need dry conditions for the oothecae (I do not know.).
You can also try using net cages to breed roaches. Just keep some substrate on a plastic sheet on the bottom of the net cage and keep the substrate moist (Because you have so much ventilation in a net cage you probably will not have problems with too much moisture.). Put slabs of bark on top of the substrate in the net cage for shelter for the roaches.
Other types of cockroaches, like the Blaberidae will probably do better with different care, with deeper substrate and some rotting wood. The Blaberidae are usually easier to raise than most egg laying species of roaches.
