I checked my bottom board and found Tropilaelaps & Varroa mites. Not too many around 5 of each after a week. I gave the bees Apiguard on the 20th March and none of it has been touched yet.

I am thinking of investing in Varrox to vaporise Oxalic acid crystals as I read that this is one of the best methods to use which doesn't affect honey produce.

Has anyone tried this and let me know can it be used anytime out the year? I would use it once a week for 3 weeks to try and clear the mite cycle.

Thanks
