I was using the 3 drawer drop through egg version and decided I didn't like the mess of it and/or potential messes. Yes opening the 2nd drawer first helps keep down potential messes, but some stuff still fell out through the opening and onto the sides of the drawer unit. Since I do this in my foyer and I do not like bugs in my house I closed back up the top drawer and now have 3 drawers of mealies of all ages. It's working just fine and I don't have to worry about the mess or move them around so much. If you start with the 3 drawer with the screened in cut out - save your cut out just in case you decide not to keep it that way. Try it for awhile and see if you like it.
Now that I have mostly larva again and the beetles are presumably all gone - I will probably work on merging all the larva back into one drawer to separate out the next generation from this first generation. That will give me an opportunity to clean out one of the drawers of all the frazz, skins & add fresh wheat bran.
