There was a discussion on another forum, I will have to look it up, that suggested the resistance found in some parts of the US could be time sensitive. In areas where overuse of Apistan lead to resistance and the beekeepers stopped using it for a period of years, some are able to use it again effectively.
That said, it would be folly to blindly trust the effectiveness of any treatment unless you are on scheduled treatment cycles and treat anyway without mite checks.
We are noticing, for the first time locally, some resistance to Apivar. A beekeeper I know sometimes leaves the strips in all winter. Why,![Unsure :unsure: :unsure:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
