There's a crack in hive 2 between brood and super in one corner which I need to seal up. I stuffed it with twigs for now and see what the join looks like when I switch over the brood and super (to put the latter below) in a few weeks time.
The Apiguard in both hives is now down to one quarter left in sachets. There was a strong smell of thyme in both hives when I opened up.
Well, when I pulled out the varroa floor of hive2 things did not seem too bad. There was a fair smattering of varroa, and I estimated about 350 on the board. Given 9 days since the last inspection, that's a daily drop rate of nearly 40. This is not typical drop, of course: it's drop in the presence of Apiguard which is supposed to result in lots of varroa falling through the hive. However, when I took a look at hive1 there was a somewhat starker result. Huge numbers of varroa. I marked out a small square and counted hundreds. Scaling this count to the size of the whole board indicated that I was probably looking at a couple of thousand little dead, red mites! Was it really only 9 days since the last inspection? Had I turned the varroa board over at that stage to get a clean count as I had thought I had? Does this indicate something good, in that there are lots of DEAD varroa? It's definitely one for reference to a more experienced keeper. I suspect I'll need to initiate some other treatment now or soon. I was planning to whack on some oxalic acid in December anyway, but perhaps this result dictates that I'll need to do something before then. Having said that, the colony seemed really healthy (apart from the very low brood count): there were loads of bees and the stores looked good. Curious. I feel somehow confident that hive1 will come through fine, but am well aware that this could just be mindless beginner's optimism. Off to the Apiray to ask the experts tomorrow . . .
