I treated with Apiguard. Temperatures were ideal. Treatments have been off for at least 7 days. Today I pulled my varroa trays after a three day check. Yikes. Two trays have 75 or so mites, so that is 25 per day natural drop. I guess I did smoke them first before pulling the trays because I needed to pull inner covers for something. Would that skew the results so much? So now what? I do not have an O.A. vaporizer or anything. I do have two trays left over. Shall I put them on? Would a powdered sugar treatment or two be sufficient before winter? Why do I worry about them having enough stores for winter when the varroa are going to kill them anyway? Any thoughts?

I would feed them and do at least 2 sugar shakes about 10 days apart. The queen should have gone into a reduced brood production mode so developing more varroa isn't as big a concern as it was. The sugar shakes should knock down the adult mite count darastically and a follow up should catch those remaining any those that hatch out from the last "big" brood set of the season.

twb,i have a pfd file that is totally for varroa control. It has several different methods for killing varroa mites. I think this might help you with your problem. The web sit is: http://www.biosecurity.govt.nz/files/pests-diseases/animals/varroa/control-of-varroa-guide.pdf

I wrote in my original post that Apiguard had been off for 7 days but I realized later that the day I took it out is the day I began my 3 day mite drop check. The stuff was probably not too potent at that time anyway but I wanted to clear that up.
I will probably do a couple of p.s. shakes if the weather stays mild.
Thanks for the encouragement. Lots of info in your pdf. I will probably refer to it again.
