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

Timothy about Varroa

After the last entry Timothy the beekeeper mailed me this: 'It's weird to see mites outside the hive. The mite actually drains the blood from the bees just like a tick. The main problem with them is they spread viruses which actually do the killing. Varroa on it's own will only weaken a hive. Varroa and viruses of which there are over 15 will kill the hive. In the hive contaminated material is very rarely exchanged but the mite does this by biting one bee and that then becomes contaminated and then biting another and so on: spreading the viruses.'
