Varroa snelgrove effect

Hi Fatshark
I use a record card per hive with spaces for dates and next action to keep me right

I followed the DR system last year, the card keeps it simple. I think some people are put off, because the technique is a wee bit repetitive and confusing to read. For small time keepers it's a much undervalued system, with hopefully a positive impact in early season varroa control.
I did have a spec saver moment where I opened the doors on the bottom board locking the top lot in and went on holiday for 10 days, they were fine

Hope this year we can get the timing spot on nemphlar
I have senior moments which result in similar things happening
