My first summer with a hive and things are going well. Except lately, for some reason even being near the viewing window or sitting to the side and watching them land is resulting in me getting stung. I haven;t been making any sudden movements or aggression towards them but for some reason they are going for me lately. It was about 720pm here, (NSW Bathurst) and nearing sunset. I used to be able to inspect the window and watch them without issue. Is this normal?
