I have no experience with hive beetles, and hopefully never will. It is my understanding that the bettles end up destroying the wax comb in the hive. I don't believe they do any damage to the honey (other then perhaps eat it) that would contaminate it.
Are you aware that Dadant sells a hive beetle trap?

However since Small Hive Beetles (S.H.B.) are temperature sensitive it will be far more effective during late spring to fall when beetles are out of the cluster and most active. Directions Included with your West Beetle Trap are wooden spacers needed to modify your bottom board, to allow the honey bees to enter and exit the hive while the West Beetle Trap is in place. Before installing the West Beetle Trap, thoroughly clean and scrape, if necessary, any debris or burr comb from the bottom board that may interfere with the proper placement of the West Beetle Trap. It is critical that the trap is level before adding the vegetable oil. Place trap on bottom and fill 1/2 with oil, purchased separately. Place cover on trap. Do not pour oil through the trap cover, as any spilled oil may cause bee mortality. At this time you may reassemble your hive and start trapping beetles! Periodic cleaning of the traps is necessary. Check traps every 7-14 days. Tips The manipulation of your colony will disturb the S.H.B. hiding spots causing them to move around in the colony and find the trap sooner. Storage and Disposal After use, discard used oil in an approved manner. Clean traps and store away from direct sunlight and any pesticides.
Once again, I have no experience with this, but tend to try and avoid using any pesticides on or around my bees.
If anyone has experience with SHBs, I would be interested in hearing more about it. There has been a few post to date asking about how to deal with them, but I don't believe we have found an 'expert' yet.
