My Hive Is Dying :(
At least, I think it is.
I'm a first time beekeeper, and I thought I did everything right. I bought a pack of bees in spring, put them in their new hive, and they seemed happy for the first month or two. There was a large spurt of growth in the first few weeks, when the queen was laying eggs. They ate up sugar water like crazy, built comb, and were bearding on hotter days. So all good signs.
Then I noticed hive beetles crawling around about a month ago. I added nematodes to the soil, and places beetle oil traps in the hive. The traps did catch a bunch of beetles. But, I never really saw the beetles hurting the comb.
Now, maybe 90% of the bees are gone (no dead bodies or anything), and the comb is almost entirely the dark brown brood looking stuff, with almost all empty cells, and pretty much no honey stores. There are still some bees, but they seem to be no longer eating the sugar water. It was like they had one big growth spurt, and then disappeared. I'm not sure if the queen is still in the hive.
Is there anything I can do to revive my hive? Or is it too late in the year? Despite this seeming failure, I still do love this hobby. Any advice would be greatly appreciated! Thanks
