Country rubes screened bottom board and a beetle trap

I'm so excited! I ordered a country rubes bottom board today.

This is a small hive beetle trap that sits in between two top bars. You fill it with veg oil and the beetles drown. I ordered one as well. I have only spotted one beetle this year, but I thought it would be fun to try out.

Is there a bottom board made to do it all- shb, mites and ventilation?
