Well that was disapointing.
After one year of using two Hive Doctor Base I have binned both of them.
Basically the problems I found - The back tray is extreemly difficult to use due to being located behind the back legs.
The trap area is too big, it basically became a big pollen trap not to mention the bees also could get through the trap so the trays would be full off beetles, pollen and bees. In fact the "beetle" gaps in the base distorted and opened up so the underside of the board as the main entry/exit point instead of the front entry with the trays off.
Also the plastic clips that hold the trays up break way too easily.
So for anyone considering purchasing one, unless they change the design... I wouldn't bother
Lucky for the AJ beetle traps that keep filling up with beetles.
Now to make myself a new base.
