Hadn't seen these in years...They used to appear every year and we had a downpour yesterday and this is what I woke up to....There's thousands of them....

The sun came up good looked like they were gone and went walk in my back yard ....Them things started coming out the grass so bad you can't breathe....Can't see the bark of the tree they so thick.....I hope all they are is mayflies but I hooked up the hose sprayer and hit it all with termite and carpenter ant killer to be safe......

Looks like mayflies to me.
