I have a swarm of bees that was captured in a bucket with screen ventilation earlier today. Temperature is around 80F. Unfortunately, I took possession of them at dusk, and will need to leave for work before daybreak, so will not be able to get them into a hive until tomorrow evening. What do they need to survive in that environment? Is water sufficient, or is some other food source needed? I'll make sure that they are kept in the shade tomorrow.
