Compared with last year the Varroa drop is quite low, at most 20 per day. So I have decided not to give a second treatment to any of the colonies.
THe first colony was very low on bees, which does not look good for winter. I will need to give it some insulation in deep winter. I wonder if the Apiguard has made some abscond?
I checked to find only a tiny area of brood, I wonder if the Apiguard has stopped her laying.
THe first and forth had not taken down any more feed so I removed the feeders and gave the syrup to the others.
