A small nuc on 4 frames which had a new laying queen and about 3000 - 4000 bees at a rough estimate had been completely wiped out by wasps today. It was beeless and had hundreds of wasps inside robbing out the stores. It was ok two days earlier although I noted that the wasps were starting to pay it attention. It was closed down to a beespace as well 2 days ago so the wasps had no easy access.
I have never seen a wasp problem as bad at my main site.
I had to stop queen rearing a month earlier than planned as the apideas were just cannon fodder for the wasps. I moved about a dozen apideas to my garden a few weeks ago which is about 3 miles away and they are fine, the wasp problem seems to be very local to the other site.
I took the precaution of closing down all entrances to as small as possible as the wasps seem able to suss out the weakest and then pick them off one by one.
