Trust me d lardarius is soo damn common here i could find 1000+ in my house. I have a colony of lardarius at about 50+ they breed quite slow at the start[depends on how many you start with i started with four on Jan 25 and now have well over 50+.] With one gravid female you could propably get more then i did see i didn't know how to properly keep d lardarius at the start. Water[a little squirt or mist] helps with the egg production. Thus more larvae hatch[which for some reason my larvae started out as these orange dudes that are slow then now they are really dark and run like mad and eat 10% more.] what do you plan to feed your new colonies? I feed mine fish flakes,dog food,catfood and sometimes meat. Mine are ment to eat dead mealworms and stuff.
