Gnats? Thousands of them!

My pool screen has no holes in it, but I get thousands of what look like gnats floating on the surface in the afternoon/early evening. My pool has no problem skimming and filtering them, so what I’m looking for is any ideas where they might be coming from. We noticed this two years ago (our first year) and last year. But it seems this year is exponentially worse.

We don’t see anything flying around, as gnats would do, they just seem to appear on the water. I wonder if they are behind the pool/coping, and just end up emerging right at the waterline where they live out their lifecycle for the day, only to be followed by another hatching the next day.

Thoughts? My chems are consistently as shown here.

Had the same thing in my pool earlier this week. We had a stretch of wet weather and I think that caused a hatch. Worst I have seen them in years. Ours were flying around, but not nearly in the numbers I would have thought considering the amount I saw in the pool.

Skimmers/filter took care of them. My chems are also all right in line.

The whole episode only last a day or so.

In the past it seemed to be just a couple of annoying weeks. This year, it’s been a couple of annoying months. The pump, filter and skimmer take care of them, just to have it start again the next day. Also, rain or a dry day doesn’t seem to matter. I’m about to bug bomb my lanai!

Check out Bifen XTS. Sold at Walmart and Amazon. Someone recommended it a while back for ants and other yard pests. I sprayed it on my yard 3 months ago and haven’t had ants, mosquitoes, gnats, or anything all summer.

Those are not gnats.
