@Frindis @Pifanjr and whoever else was talking about spiders, we now have large, flying poisonous spiders in Tennessee. I'll have hundreds of black widows and brown recluse spiders on my property, but one of the reasons that doesn't bother me is BECAUSE THEY CAN'T FLY!
Utilities workers here have special reaching tools they use to avoid black widows when they have to work anything to do with water. I have to reach around the black widows or scoop them out of the pool skimmers so I can clean the leaves out of the pool or hook up the vacuum, but I draw the line at having one fall out of the sky and land on my head.
Here's a nice picture of one of our new flyers:
Note: that is not my hand, and they don't really fly. They make gliders out of their webs and glide until they are over my head, and then they let go.
