I think I made a rookie mistake yesterday. I applied the MAQS. However, I not only took off the plastic but also the paper wrapper. When I looked at them today there were an abnormally lot of dead bees around the hives.
I would plan on going back out with the tools to do an Oxalic Acid Vapor treatment. As long as it’s over 35f I do them. MAQS is hard on queens for whatever reason.
