I've heard the adage about Swarm in May and Swarm in June, etc., but I'm wondering when it's really too late to catch and rehome a swarm. I just got a call about a small swarm on a guy's house. They've been there a bit because it appears they've built some comb on his house. It's about the size of a soccer ball, though I don't know how much of that is comb.

I'm wondering if I should try to combine this swarm with another I caught about a month ago that is almost ready for a second deep, or if I should catch and hive it in a new hive and let it get after it. I expect our dearth to start any day now as dry as it's been for the past month.

Thoughts from you veteran beeks?

TIA
