Although we do not have SHB in the uk yet (no reported cases) Its an odds on bet we soon will have, so I have been thinking of ways of destroying them to no success.
In Africa where they come from they pose no problem as they are kept to small numbers which the bees can live with. If this is the case then, perhaps, the attitude should be, we live with them, by keeping them to small numbers.
My thoughts then turned to a trap. They like all scavengers of this type seem to like dark corners and crevices. I plan to make a trap and test it on wax moth until the SHB arrives. The trap I plan is basically a hollow division board or very thin frame feeder. Two thin sheets of material from the art shop stapled to spacers with a gap large enough for the prey but to small for bees to enter say a strip of masonite board I think you call it around the edges with gaps for entrances. Before stapling the second side on, will put barrier rings of mouse/rat trap glue around some bait (honey wax and possibly some melon skin) then put the board in the hive to hopfully do its intended job, may even get a few varroa mites as well.
The mouse/rat trap glue is a non setting glue something like evo-stik( not sure if you have in USA) you squeeze it out of the tube in a circle around some bait on a piece of paper and put it on a mouse/rat run (like any mouse/rat trap) and when they set foot on the glue they stick and the more they struggle the more they get stuck next morning its just a case of humanely disposing of them. With the beetles or moths they could be of sufficient numbers to make a bridge across the line of glue hence several rings. Just an idea but I thought it may help you guy's or prompt an version of your own.
