Yes ! I’d be a bit nerves about the drip method. Dampening weak bees might not be a good option unless no other choose. Wish he/she had the iron ! I don’t have the directions here for drip temps n other info. I know Dees been at this way longer than me with these nasty critters. Just before our temps took a dive I recheck n did a powder sugar dusting ( I know it really won’t do major good) but I was doing any n all manual treatments this Autumn also.
What was/is the affection rate presently … Here my bees are really dropping off in numbers. My colonies are okay here but way too late for treatments. We’ve been near or below 32 dgs F … Several days of 25 n 27 dgs near Seattle. Today near 40’s F but suppose to drop back into the mid to low 30’s again. How long of a period (how long n when) is your above freezing period ?!
I’m satisfied with my two large colonies. It’s my small double deep Nuc I’m concerned about … I’m just trying to get my first Nuc thru the winter. Nothing venture … Nothing gained, as my mom use to tell me ! I lost two nice colonies because the mites got ahead of me this year late August. But was able to easily get three others thru with much less mite count. I learned this season to treat each hive as individuals. I guess I waited two weeks too long for two hive trying to wait for a good day n perfect weather but lost !! Live n learn ! It’s an interesting learning curve ! Luck I was able to use the honey supply in those two die-outs to totally supply my honey needs in the healthy other three.
