It may be the time of year or the freezes we had, but I went through 19 hives yesterday and did not see the first SHB. 12 of these hives had pollen patties on them for 2 weeks. A lot of the patties were gone or just a tad left. I renewed them and put them on the rest. I cut the patties and adjust the size to the size of the hive by guess work.
