I have seen two types of SHB traps here in Oz.
One, in three versions, allows the beetle to get through a slot but not the bees, then the beetles are killed by something, oil (and vinegar), a natural powder (diatomaceous earth, hydrated lime), or a chemical.
The other is a mat with a furry side. The bees chase the beetles into nooks and crannies and the mat hangs like a frame with the furry side against the wall. The beetles get trapped in the strands. If it is too far from the wall, bees can get trapped too. I find this mat more effective that the organic traps mentioned above and I'd put two in the brood box. One on either side. I don't use the chemical traps.
What I find is even more effective than the mats is modifying the lid and bottom board, such that they become SHB traps. I notice the Australian lids seem a little different from the US ones, but the idea should work with the latter too.
In Oz, the lids I've seen have two parts and don't extend over the edge of the box. The metal part can be taken off by removing four small nails in the corners. The lid is then turned upside down and small vents are secured in the lid. I put 8 vents around the outer edge. Then the same organic powder used in the traps mentioned above can be spread and the bees chase the beetles through the vents. I use hydrated lime, as that is cheaper than diatomaceous earth, which has to be considered, due to the amount used.
The bottom board is separate from the brood box, which just sits on top of it, rather than being connected, as we usually find. Then a screen, such as a propolis collector, becomes the new bottom of the hive, with the entrance about level with it. Under that is a tray with the same organic powder used in the traps mentioned above. This tray can be removed from the back of the hive. There is a flap of plastic that covers the tray door, to stop water getting in, which is secured between the brood box and the bottom board. A local bee supplier intends to make them. I like them better than the Hive Doctor bottom boards from NZ, as they are wooden and would therefore provide more insulation to the hive.
Thus the lid and the bottom board are traps that can be checked without disturbing the bees, much (re lid) or at all (re bottom board).
Hope that helps.
