Winter Loss Report 2025 (for Winter 2024/2025)

Every year we like to see how well the bees did over the winter. This survey does not replace the official OMAFA Winter Loss survey, which is used for provincial, national and research statistics and purposes, but we do like to see what is happening in Ontario with our members and followers.
 
Below are the summary points for the 2024/2025 Winter period.
 
In the spring of 2025, a total of 642 Ontario beekeepers were included in the Ontario Beekeepers’ Association’s (OBA’s) Winter Loss survey representing 27,465 hives that went into the winter in the fall of 2024. The overall average winter loss was 33.5% and median was 36%. Beekeepers were asked about in-season losses for the first time this year and reported an average in-season loss of 8.8% for a total loss of 39.3% over the previous year of beekeeping.
 
Beekeepers with less than 50 hives reported an average winter loss of 40.5% (median 40.0%) while beekeepers with at least 50 hives reported an average winter loss of 31.8% (median 29.9%). For the first time this year respondents were asked to report on in-season losses prior to winter wrapping in the fall of 2024. The average in-season loss was 8.8% (Figure 2). This includes an 11.3% in-season loss among beekeepers with less than 50 hives and an 8.2% in-season loss among beekeepers with at least 50 hives.
