That’s what I do. But with a sublimox. It works very wellRemember that trickling OA kills any open brood that may be present, I am looking at using a Gas Vap and treating from the top using a modified crown board. The crown board has around a 25mm spacing above the frames with a hole drilled in one side into which the gas vap is inserted. The vapour enters from above and decends through the combs (rather than trying to rise up from below) If you look on YouTube at a lot of professional beekeepers they don’t fully seal hives when treating so I’ll be trying that this year and checking for mite drop.
