My issue may not be any kind of a sting-y anything, but they do just annoy the *#;'% out of you (me).
Maybe they're a local blight here in NE Texas, lucky all you others if so.
Flying ants.
During a certain season - which we just arrived at - they suddenly 'arrive' - sporadically, but on each occasion they do so ALL AT ONCE, and evidently either VERY THIRSTY, or HOT
I'll get to the pool - to monitor, check, test, clean, or, who knows? Swim (ie float and doze!) maybe!
And it'll be covered in them. And the skimmer sock and basket will be full of them. And I'll be all over the pool with a leaf net gathering them up just to turn around and find a bunch more have landed where the surface two minutes/seconds ago was spotless

Does ANYone out there know how to hold them at bay?!
Maybe set up a ring of fire around the pool?!
