They "set up" a large pool? So I assume that means an above ground. I'm thinking it may have a slow leak, and the mosquitoes are breeding somewhere on the ground around the pool rather than in it. Possible? Do you not have some kind of health authority in charge of the campaign against West Nile? I'd contact them, too, because keeping the skeets out of your house is important, but maybe of even more importance is cutting down on the spread of the disease.
