It seems to me that there is no action to be taken over mosquitoes breeding
in the pond because I can't see the larvae in the water. Is that correct?

I'd think so.

Goldfish etc. take care of the larvae effectively, and some insect do
so as well.

Rather than spraying DDT, which is banned in most/all of the world
AFAIK and pretty unavailable, you could consider floating "BT" rings
sold for the purpose, at least in the US. Information is available
online -- these are thingummies that contain "bacillus thuringiensis"
toxins that are supposedly harmful to mosquito larvae, but not to
other pond life.

Or download the directions for such a ring, give them to your
neighbor, and toss a styrofoam ring into the water. Maybe add a
goldfish if you want to look at one. Likely just as effective...

Why not instal a pump that keeps the surface of the water moving a little.
Mosquitoes don't like that and prefer stagnant water,AIUI.
