I-10 and Hwy 359. The furthest fields are north of Katy, about a 15 minute drive, with most fields less than 5 minutes. Just 30 minutes from downtown Houston on I-10 west. Most of our mallards show late season, if it gets cold enough up north to push them down. These diseases will also take other wildlife with them, shore birds, ducks, and many other kinds of birds in the region.
Hunters are the best means of reducing the overpopulation.
Today more than 3 million winter on our Texas prairies. The mosquitoes in the marsh are awful. Sometimes I feel my blood supply is a quart low after a hunt. You will encounter a few during dove and teal season but nothing like the marsh, in fact a can of mosquito spray may last several seasons when hunting with us. We are home to a much smaller, freshwater mosquito which is very nocturnal.
