Here are some good links about breeding dubias. I’ve found that Dubia Roach Depot has more than enough information on their website. Be sure not to use textured plastic, look closely. I thought I had untextured but I accidently used textured plastic and some roaches can climb it. Keep in mind that it is possible to develop allergies to them but it takes very long to set in (it would likely take years or decades). The allergies also affect seafood so if you like seafood see the second link.
