I have a screened Varroa bottom board and will be treating with MAQS.
Do I need to remove the entrance reducer when treating? OR, just leave the screen open to the air by removing the plastic drawer insert while keeping the entrance reducer in place?
In other words, do I need to remove the entrance reducer (as the treatment calls for), or is the screened bottom enough opening for airflow?
I would appreciate any help I can get on this issue...
