ok then .. i have been looking around and the Lateralis are INVASIVE??? then some people say they cant breed at low temperatures .. i plan on leaving in garage ...... i think im going to rephrase my question ... what is the most least invasive cockroach i live in the mountians of northern california so cold wet winters and hot dry summers
Hi Andy. The others forum members have definitely been steering you the right way. I make my bins the same way as Matt, with hot glue and a Dremel tool with a cutting disc. I make an opening on opposing sides about 3x6". But a little bigger or smaller might be appropriate depending upon how humid it is where you will be keeping them.
I've been keeping Blatta lateralis now for several months and have had no problems with escaping and or infestation. I read those other posts too and was also very leery. For me, they have been no different than any other roach species. They don't climb, they don't fly and mine don't escape in any way. They are also probably a little more cold tolerant, which sounds scary, but it also means they are likely to do better in a cold garage.
The dubia or discoidalis will be a better size for your dragons as they get older, but the lateralis will be just right for alligator lizards and small beardies. You can handpick the right size dubia or discoids for any size predator.
One of the things I like best about the lateralis is that they don't try to hide when you drop them into your animals enclosure. They just run around until they get eaten. The others are all pretty good burrowers and hiders. I usually hand feed the others ones with rubber-tipped forceps.
If I were you, I'd try two or three species and experience the difference for yourself. Get the roaches going ASAP as they take a while to really get up and running enough to feed them out in substantial numbers. You'll also have to learn how to sex them, so you can feed out the males and save the females for breeding. But more on that stuff later...
