Oxalic Acid Vaporisation Treatment

It’s that time of year again when I like to zap those pesky Varroa mites with an Oxalic acid vapour! Although deadly for Varroa mites and humans, it’s a harmless treatment for the bees.

Hopefully, with limited brood this time of year, there should be very little Varroa mites protected in capped cells.  Therefore, the oxalic acid vapours should kill those Varroa mites attached to the bees, they’ll drop off through the open mesh floor and come spring, there should be a significant reduction in their numbers which in turn will reduce their reproduction. That’s the theory anyway!

Having borrowed the equipment from the East Lothian Beekeepers Association, I felt I should use the equipment as quickly as possible so I could pass it on to another beekeeper. However, family commitments and a flat battery in the equipment meant I couldn’t do the treatment over the weekend. With the battery now charged, thanks to the loan of a charger from my friend Euan, I was ready to go. Only one problem, as it’s potentially a dangerous procedure, I needed a buddy to do the treatment with. As it’s a lengthy process, Stuart didn’t have the time during office hours so it was Mum to the rescue! She accompanied and helped me at both the Gosford and Archerfield Apiaries and we got all the hives treated today.

Hopefully another step forward to a healthy and happy Spring for the bees!
