I haven't used Bayvarol or Apistan for 4 yrs and had some spare strips in my shed so thought I'd see if my mites were still resistant.
I put a handful of bee's in a tub with a mesh floor with a suspended strip of Bayvarol inside and left for a day.
The result was 23 dead mites.
I then put then drowned the bee's in water with a dash of washing up liquid and seived the resulting mess and found 1 further mite, so think i had a pretty good result that mine are ready for a change of attack. So had a quick search for who was the cheapest for Bayvarol and found:

Never used them and have no connections but have ordered 5 packs to give the mites a quick dose.
I will still follow up with a winter dose of oxalic acid, but thought everyone might like to know that resistance does seem to disappear over time.
4 years ago i did a similar test and had something like 3 mites drop when treated with bayvarol and 20+ when drowned and seived.
