I have 3 hives a few feet from each other, a week ago they all had the odd spot of faeces on the hives. I had a look at them today in the passing and the front of the strongest hive was heavily splattered above the entrance. the hive is on double brood and I added a super about 5 days ago. I intend to look in tomorrow to see if there is any faeces on the frames.
If I spray them with a thymol syrup mix do I just use enough to give all the bees a drench?
I have enough boxes and fames to do a shook swarm but don't want to take drastic measured just yet.
they are facing a field of rape but not taking much of it yet.
