I live in Florida and have lots of ants on the surface.

I have an old pool and there's no skimmer door (and no slots/holes to add one).

Some of them go into the skimmer (very few), but even those that do make it in there just sort of swirl around.

I just resurfaced and the company said with the addition of a vacuum line and a pressure-mounted skimmer door this problem would be solved.

However, I'm can't find a pressure-mounted skimmer door anywhere (and the entrance walls into the skimmer are on a 45 degree angle, so I'm not seeing how a pressure-mounted door would work). I would really appreciate any suggestions.
