There's a hive of bees under my house. We let them stay because they don't bother us and they scare this shady guy away (long story). Unfortunately we live in a very dry, hot area; I worry about the bees being dehydrated. Is it safe to leave water out for them?

It is totally safe to leave water out IF you take the proper precautions:

1: Make sure they have something to stand on/climb out on. Bees can’t swim like wasps and other insects, so just putting out a big bucket of water will likely cause many of them to drown

2: keep it mosquito/algae free by either dumping it out and refilling it every so often, or by keeping it closed somehow. (only accessible to the beebs)

3: there’s more but those are the most important.
