So by now you guys have noticed i am a bit of a perfectionist, so along with fruit flies i also started cultures of the following
Blaptica Dubia (Orange spotted roach) and Blatta lateralis (Turkish roaches) also looking at maybe starting the Gromphadorhina portentosa (Madagascan Hisser) and of cause some crickets so every project is important and temp control is a must for the Blaptica Dubia (Orange spotted roach), at 23 degrees there was little movement at 28 degrees they are now active and breeding. now if you smart and use only the same container and heat pads on all of them you can use one temp controller to maintain the temp on multiple breeders. the temp control is fully portable and i am just waiting for the humidity controller for the incubator i am building that is full temp and humidity controlled and also full portable.

Have you considered using peat for the B. dubias ?

Are you leaving the egg crates flat or will you eventfully put them up right?

they not flat at 45 degree angle, i heard they like peat but its a pain to clean!

I been keeping mine on peat for years now and they seem to breed faster and seem to be happier than being up right on egg crates. Also the peat actually stays cleaner for longer,

I also have Isopods added to clean up after them and then recently I have added meal worms to the mix.

I still keep egg trays and bark in the container for hiding space.

ok so add the peat they very happy you where right also got 15 adult Gromphadorhina portentosa (Madagascan Hisser) to start breeding i'm not to fond of the Turkish roaches so i may feed them off and just keep the Orange spotted and small Madagascan Hisser as feeders.
