For Crix I take baby cereal, dry milk and a touch of CaVitamin dust. I honestly don't even measure but I know there is a recipe out there.
For Mealies I toss in any and all of my stale breakfast cereals....cheerios, kix, honey puffs....whatever. Or oatmeal or dog kibble. Layer some papertowel with them too.
For waxies I mix honey and oatmeal to a dryish glob and feed that. As soon as I started feeding that mix they started breeding well too. Layer some waxpaper and papertowel with them.
Roaches....they eat anything! Dog kibble, cereals, etc.
The roaches and crix get fresh greens every night. The worms get a light misted papertowel over them.
