Hand out bug repellant. Avon's "Skin So Soft" is something I have heard for years, repels mosquitoes, even though it's not marketed for that purpose. It seems to be a safe, possibly environmentally sound option. On the tv station CBS 11 I-team website, there is information on a scientific study that included "Skin So Soft".
In some areas places where stagnant water gathers maybe drainage could be set up or some filling in of low ground areas where puddles form could take place.
Men could help in some areas, since they don't get pregnant, and use a large broom to sweep up/out puddles of water. Of course this should mainly occur at the times of day that mosquitoes are the least active.
I've also heard that smoke repels mosquitoes. I don't know if they can be killed using smoke, if so, maybe swamps or other areas could be treated with smoke, as long as it doesn't adversely effect the ecological balance and the people who do the smoking are equipped with safety gear.
I worked in a place rife with fruit flies, they tried things to get rid of them, fly strips worked very well. Is it possible to create fly strips that have something to attract mosquitoes.
