I had one slow hive out of a lot of 6 nucs from one bee supplier. I was shown the queen when we transferred the nucs to my equipment. That was the last time till today that I have been able to find her in the hive. My wife spotted her hiding in a hole in the bottom corner of a frame and she would take turns peaking out each side of the frame as I turned it to examine. Any how the supplier mentioned that the nuc was a bit on the light side but should catch up. The others did really well but that one was always slow to get going in the morning and not a good laying pattern. A month ago I finally put the hive on a screened bottom and put in a stick board. Fifty or so mite drop in 24 hours from about nine sparse frames. I decided to try hopguard and got 125 or so mite drop on first day with the strips then down to about 25 a day by day 6. Since this strip doesn't get under the cappings I opted to treat weekly for three weeks to catch the mite crops that emerge with new brood. The third set of strips show about a dozen mites in three days and the capped brood is losing the shotgun pattern and there is a lot more foraging activity. I had thought I should requeen and scratched my head over why one out of a bunch could be so different while the sister hives did so well both here and at my sons yard. One is his best producer out of 30 or so mixed source hives. Maybe she is a good queen that was kept on her knees by the mites, and I was in denial. If I could have found her I would have pinched her and given them a frame of eggs from one of the other hives and let them raise one. Anyway that is how she survived! I will see how she does now and if she cant get enough stores together by fall, I will off with her head and combine with another hive. If this were a commercial venture for sure I would have to be a lot more decisive as one can sure waste a lot of time treating each hive as an individual. There was just the faintest of light rain this morning and the girls were out working on the buckwheat I scattered along my fence lines. Probably my main flow right now is honeydew from the aphids in the oak trees. Thistle, joe pye weed and golden rod are not really on yet; terribly dry!
