There is evidence that Denmark has low reliance on synthetic miticides.

In Belgium (as well as in Holland)beekeepers have been using Apistan (fluvalinate) with success for approx. 15 years, until the mite wun the battle by becoming resistent to fluvalinate. Now the official Belgian beekeeping orgnizations recommend (+ sponsor) the use of Apivar (amitraz) + Perizin (coumaphos).
According to a March 2001 survey, only 14% of Danish beekeepers and 22% of Danish colonies are treated with synthetic acaricides (Bayvarol, Bayticol or Perizin). By contrast, 86% of beekeepers and 77% of colonies were treated with a combination of "apicultural techniques, physical methods and organic acids". The most widely used organic acid was formic acid, which was accounted for approximately 80% of organic acid use (formic, oxalic and lactic acid). Although heavier reliance in synthetic miticide use was observed among beekeepers with more than 200 colonies, fewer than 40% of larger Danish beekeepers used synthetic acaricides.
Similar trends have been reported in Ontario, Canada, where a terrific effort be beekeepers and their technology transfer group greatly increased the use of formic acid. Over 80% of Ontario beekeepers are reported to use formic acid.
