All I see is specks. :)

Seriously, if you want an identification, you're going to need a MUCH closer view. I don't know whether there are any phone cameras that can get that close. You might need a good camera with a high quality macro closeup lens. Ask friends and neighbors who are into photography.

Once you have a close enough photo to show detail, you might try these folks.

Or just capture a few in a jar, and take them to your county extension office.

Or leave them alone and see what happens -- they may just vanish in a day or three.

See closeup thank you.

Might be a swarm. Had that happen with a house once. Thousands of house flies in the attic/SE corner bedroom. Was horrified, thinking there was something dead. The flies would congregate on the outside of the wall in the morning and go inside the attic in the evening. Spent several hundred dollars having pest control treat attic and trying to seal windows in the bedroom from the attic.

Talked to an extension agent(local 4-H) who said there is a phenomenon where insects swarm temporarily like that. Usually only happens once. In my case, that was true, never happened again.

I’m surprised the “termite people” couldn’t tell you what they are if not termites. I can’t tell for sure but when we had some swarmers that looked similar, I was told they were webspinners, which are of no concern.

The close-up image clearly shows these to be gnats. Adult gnats are very short-lived and do not eat anything. A flying insect spray will kill them on contact. They could also be vacuumed up.

My money’s on winged ants. Has it rained lately near you and/or when you first noticed super humid? That usually will bring the swarmers this time of year. Multiple types of ants can and will for a day or two- literally that’s usually it.

Has to do with mating process’s. Girls no wings. Guys winged. Queen lays gizillion eggs and when it’s time they all hatch and fly out to mate and ruin picnics everywhere. ewww

Carpenter. Black ants. Several types. Just google and you’ll see. It’s almost impossible to tell the difference between them and termites naked eye. Trap a few and grab a microscope if need be and google side by side comparison termites versus winged ant and once you’ve narrowed you can then figure out which type of ant if need be.

Winged ants are far larger than the insects asked about. Also, ants winged or not have relatively long, jointed antennae, and the gnats above have shortish straight-line antennae. Note how the ants pictured above have elbow bends in their antennae.

Logician I think you should magnify both images of the few she blew up and the image I posted. The antennae look identical. Also, even among winged ants certain types of ants will look different as different ants have different characteristics and that is what allows us to tell them apart.

It would be interesting if OP responds I am curious if her problem of them swarming her garage was short lived. If they are winged ants then I suspect they would be as would only correspond with the mating days they hatch and go above ground.

I did look both images in the magnified mode and the antennae are distinctly different. The foreleg pair of the gnats is easily confused with their much shorter antennae. All ant species have the longish elbow-jointed antennae.

Winged ants have two pairs of wings and when folded, they largely obscure the body. Gnats, with just one pair of wings, allow the silhouette of the body to show through more distinctly.

For either ID, the spray or vacuum would work.
