Thank you

and I have been blessed by you all

Tom!
These are tiny little gnats that come out when the trees leaf out, through May 31.
Then the adults die off , the immatures go into dormancy until next year,or the mosquitoes eat them.
They first swarm in clouds, then after a week or so they start to bite; flying in your eyes, nose and ears, and crawling in and up any opening in your clothing.
They draw blood and leave itchy welts; some people have allergic reactions to them.
They are unhalted by bug spray, when in full bite you must don bug nets and tuck in every piece of clothing pants on up if you go outside.
They are a pain!
When they leave the skeeters come out with their diseases, along with ticks and deer flies, but at least you can spray down to protect yourself form them.
I don't like flies of any kind, and especially in my house.
If I can't get them with a swatter, I use hair spray to stop them from flying; it works good for hornets if one gets in
