You will also see that there are canals just inside the perimeter fence joining each of the four large run-off ponds. To the north and the east of the airport the land is mainly paddy fields.
I suspect each of the underlined items mentioned above are prime breading areas for mosquitos. Not sure if mosquitos need clearance from ATC to enter controlled air space

Strips of grass land routinely disturbed by turbine-generated wind doesn't make for mosquito breeding grounds.....
And by the time you're outside the perimeter of the airport to the paddy fields... that's about a mile away from passenger terminal.
Washington DC used to be a swamp, and there are currently large patches of grass all over the city as well as drainage ditches, etc... Yet DC isn't infested with swamp-level mosquito population because grass/water isn't mosquito breeding grounds when they're routinely exposed/disturbed.
