Hello all. I split my strongest hives into a new 10 frame box this past Sunday. I gave them 4 strong frames of brood with eggs to create a new queen. I also gave them a few good shakes of bees on top of that. Each frame had honey on them as well.
Today (4 days later) I walked down to check them and I found what is pictured below. For more info it has been a bit cool with some rain (North Vic). I haven’t seen too much activity out the front but I assumed due to it mainly being nurse bees that would be the case normally.
On top of that the two stronger hive flanking this one have no signs of this dirty flecks on them.
I fear it may be Nosema, but I have little to no prior knowledge of Nosema and how to deal with it. Some advice please!
I plan to inspec in two days when it’s sunny.
