Just my way of handling shb.......
I got a big dose of hive beetles in two NUCs I bought last Spring. The biggest boon to small hive beetles in my twelve hives is to add too much pollen patty at one time, if you do, you will find it full of shb larva. Too much space for the number of bees also makes it hard for the bees to corral the beetles and control their breeding.
ANY crevice in the hive can become shb accommodation, so I fill every gap I can, usually with elmer's glue. Ribs of all plastic frames make nice shelter for them too. The groves in wooden frames make good places for them to hide. It helps to know where to look if you are going to carry out a death sentence.
Half my hives are in the sun and half in the shade 100 feet away -all are off the ground. I found a NUC the other day with a three inch circle full of slime and shb larva. Caught it early enough to take every frame out and manually kill the larva and beetles then cut the affected part of the comb and froze the frame. This NUC was in the sun, so its not as simple as keeping hives in the sun. I found shb larva in a NUC in the shade and killed them manually -wear your glasses, the larva start out very small, look for their movement.
I treat the ground under my hives to reduce shb success, but remember, the larva can crawl hundreds of feet and the adults are strong flyers. They can also reproduce on decaying vegetable matter (melons). I found THIS link very informative, I hope you do too.

Tom, this magnet from my garage toolbox makes an excellent shb killer. You can reach down to the bottom board with just one frame out of the way. Be patient, the bees will herd the beetles round and round. If you wait, you are likely to see the same beetle again and again as the bees harass them. I also think the meaner the bees, the fewer shb you will have. Cut the end off a small screw driver and you can reach to the bottom of a cell containing a shb to kill it.
Commercial guys can't take the time to manually intervene, but I can.
