The beetle barns are cheap, $1.00 a piece if you buy a bunch. You just have to clean them out when the bees glue them shut. Use several throughout the hives, top, bottom, middle. Checkmite is approved for use in them.
Darn... Allen I forgot about that. I did put a checkmite square in the middle section as my first test (before the Maxgel arrived)... but I'll have to say the Maxforce did better... more SHB in the traps, but it's not approved. So your best bet is to use that if you have to.. I'm staying chemical free (no sugar dusting, no feed etc) on my honey hives. So my personal opinion (and most in this area... same results), full sun is the best bet in the south with no chemicals.
