January is oxalic acid treatment time for honey bees in Yorkshire. This is David Haigh spraying the varroa treatment into one of our overwintering hives at Temple Newsam. We have several over wintering hives and each one will be treated. This hive is particularly strong for January. He also “hefted” the hives to make sure they have sufficient food to see them through to Spring 2017. They all had, I'm pleased to say!
