A few weeks ago when my shipment of roaches came, I saw a couple dozen lesser mealworms and a good amount of adult stow-aways. I said what the heck, and threw them back in with the roaches. Today I did a small cleaning and a check up, and was satisfied by how many dubias I now have, but was surprised that I already have at least a thousand lesser mealworms in varying stages. Much more than I remember. Question - will these do any harm to the roaches like feed on newborns? They do make good ant food though!
