I collected one Monday that was there since Thursday. They moved, and where they were clustered before had probably 1/3 of their numbers piles on the ground dead.
So I'd say if they are in direct rain.... a few days. If they are somewhat protected they'll probably go 5-6 days. I read somewhere they pack enough food for 3 days.
Hopefully they come down to the bait hive. Did you happen to put out multiple hives so they had a choice? Is it on the ground or elevated? I have also read that bait hives seem to do better 8-10' off the ground.
I put the bait hive about 10' in a tree. I caught swarms before in it, but this is the first time I had a swarm just hang there more than a couple of hours. I just put nasonov swarm bait in the box, maybe it will help.
