Re: Swarm calls....
This summer is sort of like the one we had about 5-6 years ago. I called it "the summer without a summer".
We had nice cool sunny weather the entire summer. I did siding and worked outside and I don't think we had even one rainout day after June 1.
This year...rain and rain. Cool and wet. The white clover is still blooming in September. This summer before September we had only THREE days above 90F. That is quite rare. We've had summers where it was 90 or above every day for 90-100 days. This summer is not normal at all.
The bees probably think it is spring #2 up there in Michigan.
Internet credibility is an oxymoron
