I will have two top bars next year where research would indicate that my mite treatments options may be limited. Many on the forum have expressed concerns with the use of MAQS, thymol, Apivar, etc. although I recognize there are individual success stories with these products in top bars. OAD and Hopguard II seem to be solid options during broodless periods, while OAV may be a possibility outside of those times.
I have two questions which may or may not be related - if it was mid-August/early September and your mite count was above thresh hold levels, what treatment would you use in a top bar? Also, do you preemptively treat in early August (even in the absence of high mite counts) to stay ahead of the mite curve and, if so, how?
Thanks in advance for any thoughts.
