Okay so I know that you can feed Dubia Roaches anything you'd feed your beardie, but can you also feed them things like bread and potatoes? And if you can feed them bread, would moistening it help keep humidity up?
I would stay away from bread b/c of mold, could kill your roaches. I feed mine, baby carrots, oranges, dog food, various vegs. I also use Flunkers water crystals. hope that helps
