rain will eliminate any benefit from diatonomus earth. there are reports of lime killing SHB larvae and its good for most soils. put the earth inside the hive in a SHB trap. good luck,mike

Get yourself some chickens who like to scratch and peck (and eat larvae) in the dirt around the hives.
I have some who love to do that and they never bother the bees.

Someone had mentioned keeping game birds to deal with mites. That would require a screened bottom however.

What kind of poultry/game birds find small hive beetles delectable?
