The annual winter kill survey went out to our members, and with 27 respondents thus far, here is the results of the survey.
The preferred method of overwintering (66.7%) was 2 deep Langstroth boxes. Insulation of some kind was used for all but 6 members. Roughly 1/2 of all members did not do anything for a wind barrier. Almost all (88.9%) respondents vented the top portion of the hives. Just shy of a third of our members (29.6%) did not treat their hives for mites, and those that did, oxalic acid vapor was the predominant choice (48%). The number of treatments was pretty evenly split however, so there appears to be no consensus of members on this practice. 40% of us put on emergency feed in November.
In total, 51% of us had 1 hive or less come spring time. with the bulk of losses occurring in February or March.
