Not sure that it works very well anymore. I hadn't used it in years and did a cpl years ago and still had mites showing soon after. But I'd sell you the ones I haven't used if you want them. Cheap. Save me from tossing them out.
Mite-Away Quick Strips (can be used with a super on), Apiguard, and Oxalic Acid when broodless, or nearly so. No Apistan, or Checkmite. Mites have developed resistance, and these are persistent chemicals that remain in the wax. I won't use these.
