I was a bit concerned to see so many varroa mites on the collection board under the mesh floor so decided it was time to treat the colony, it's quite easy really, just take the roof off and plave a tray of Apiguard on top of the brood frames, this contains thymol and is supposed to kill the majority of varroa in the colony, you will never get rid of them completely! You just have to keep treating them in one way or another!
Another dose of Apiguard in two weeks time and then in late November/December a treatment with Oxalic Acid, sounds scary but you can google anything and it doesn't look to difficult.
