>The problem with sticky boards comes in post-treatment, when the mite drop is treatment-induced rather than natural.
Sticky boards show their strength during post-treatments as an indicator of the total exposed mite population. You can also use them post-treatment to get a read on the efficacy of your treatment and then use them to follow the duration of the kill. In my mind, you limit possibilities by striking a false dichotomy like washes are "better" than sticky boards or the other way around. Who says you can't do both or use either one separately for what they have to offer. I have lots of experience with sticky boards and just as much with washes, and I've learned the limits of each. Sticky boards can be unreliable during unusual brood conditions like when a colony goes queenless, or there's a brood disease ( Branco et al. 2006). On the other hand, with increasingly smaller mite counts triggering treatments, if a wash provides a false negative a colony can get in trouble later in the season, and that's a difficult concept to teach beekeepers and especially new beekeepers.
