The varroa threshold

Timothy the beekeeper answered on my Facebook post about this blog: ‘All of my hives are due for a varroa treatment in the next 2-3 weeks. As a beekeeper I try and keep infestation levels below a 1000 varroa threshold that means that I try to never let there be more than 1000 varroa in any hive. Problem is they double in numbers every few weeks. It forces me to have to put chemicals into my beehives. But if I don’t my bees will die so it is the best of a bad choice.’The bag with Varroa poison looks a bit like a feedbag and it is also put on top of the frames
