Anyone use hopguard in a TBH? My single hive failed last year (probably for many reasons, including letting them get too crowded and start throwning off swarms). But I'm not ruling out mites as the (or a contributting) cause. I have some Hopguard strips that the local guru talked me into buying. Research indicates that they're pretty effective for mites, but wondered if anyone here has used them in a TBH and if so, what were your experiences and how did you apply them?
