I could not get the site to load but I have serious doubts about it stopping them.
If you want to get SHB under control, use a screen bottom board with a oil pan. Be sure the bees cannot get in the oil pan.
When I started, SHB were out of control. I built SBB for all of my hives. Every month, for 3 years, I cleaned them out and the trays would be solid black with dead SHB. Last year i left the trays dry because the SHB numbers were so low, I just killed the few SHB that I would find in the trays. The trays fill up with pollen so I have to clean them on a weekly basis because the larvae can develop in the trays. It is a lot earlier to clean them dry than when they are full of old oil.
