What do you reckon this is?

Sounds like you don’t need an entrance reducer because the bees built one for themselves. But, if you want to make one there are some nice ideas on the forum:

Made an entrance reducer

Since the Flow hive has a non-standard opening and there are no off-the-shelf solutions for entrance reducers out there, I had to make my own. I cut three of the starter strips to the width of the opening and then glued them together. After 24 hours, I cut out the notch with a boxcutter. I had to sand the block down about a millimeter to fit it w/o raising the brood box. [image]
