full sun, and some kind of oil filled trap - I had the west on one hive, and the other hives were SBB, the west trap and the SBB with fire ants on the ground below didn't have a problem with infestation. I had one SBB that had an undesireable SHB population, (no trap, no ants, poor sun) so that hive is being relocated, possibly over an anthill. (the trick is to make sure the ants can't get into the hive itself) Under the hive they will eat the SHB larvae, in the hive is just trouble.
