I got a call for a swarm recently and when I was there catching it I noticed that there were bees flying in a hollow about 30 feet up. The guy said that they had been there for quite a few years and likes them there. I have read a little about doing a trap out but have never done it. Is it too late in the year to try to do this to get the genetics or should I wait until next year? I would really love to try to get them if I could. Any thought would be appreciated. Thanks all.
