Is it bees or wasps?
Not sure, but I'll soon find out!
I just got off the phone with Animal Control and they're sending someone out. They're not honey bees and they're not yellow jackets. They're tiny things, about 1/2 inch in size or smaller.
I googled "wasps in Texas" and apparently, there's a rare Mexican wasp found in southern Texas that actually produces honey. One of the few in the world that does. You got to be careful though, as it (the honey) can be poisonous depending on what flower they got the nectar from.
