I send frames thru the freezer for a pre-storage or pre-sale zap, but that’s it.
For beetle management - addition to using the oil traps Dawn mentioned - I no longer scrape off what I used to think was just burr comb on the top of the inner cover, but is actually ‘beetle jail’ comb. These look like little igloos of wax and always have one or two bees patrolling around them. I realized their purpose after seeing beetles scurrying madly out as I would start removing them, inadvertently granting the little buggers undeserved freedom Reading further on the nasty subject of SHB confirmed that bees do construct these holding cells for them, to effectively prevent them from reproducing throughout the hive.
By the way, I read in the same scholarly article that hive bodies painted white or red/pink are most attractive to SHB. I suppose these colors contrast best with greenery and are easier for them to navigate to. I’m sure they can smell a beehive from some distance, but it seems they also spot them. Those setting up new apiaries or those who’ve done a thorough job of dealing with them in the soil as well as their hives might find this worth considering.
