Hello,
The apithor instructions specify that they are not to be used on hives with perforated bottom boards. Unfortunately I purchased a mesh bottom board with a oil tray thinking it is better and have now noticed the beetles inside the hive.
The apithor worked well in my old hive base, so I would have liked to put an apithor in but it seems that's not an option. What are the alternatives? I want something that is effective. What is working well for you?
The purchased apithor is not necessary in my experience thanks to information shared by members here, Beemaster2, Paus, and others. I found the recommended screened bottom board using (number 8 hardware cloth), with an oil tray benefit does the job very well.

Since I have learned to keep my bees from having too much space, I don't struggle too badly with beetles anymore in my location. I will sometimes put squares of generic Swiffer sheets in the corners of my boxes if I notice more than a beetle or two in a hive. I do catch a couple bees in the sheets usually, but if there are more beetles than bees caught, I think it's worth it. I also have some beetle traps that hang over the frames which are easy to use, but I haven't needed them in a few years.
