What Mrs. River said.. I ran inspections every week through the middle of July. Didnt have one swarm!!!!! On the day of my first two week inspection one of my hives swarmed... DAGNABBIT!!
I did catch that swarm and they are building up well in a nuc for winter.
Of the dozen or so swarm calls I got this year I could NOT arrive in time to catch them. I even watched as you did, one of those swarms disperse as I was setting up.. I only managed to catch a single small swarm all year.
I blame the availability of hive locations for most of it. We lost a lot of feral colonies last winter, so the swarms this year have excellent available locations, and it does not take them long to find and use these locations.
