For the first time I have seen a few bees with deformed wing virus in one colony. The Varroa count was low going into winter, but the second inspection this year showed this problem in just one hive/colony. I have a couple of supers on at the moment to catch the OSR that is coming in. Would it be a good time to do a shook swarm on that colony when I remove the supers, or should I do it straight away?
A shook swarm won't really address the major problem of varroa.
MAQ's are advertised as usable whilst a flow is on. I have no experience of using them myself so not sure of tyheir effectiveness at this time of year.
An alternative is vaping with apibioxal at 5 day intervals (removing supers before vaping).
