In 1999, West Nile disease made its unseamly appearance in NYC--not a center of mosquitoes by any means.
Now its been reported in 34 or so States.
Louisiana is especially hard hit.
I remember hearing the helicopters spraying various neighborhoods, usually late at night as more people would be inside. Trucks were also used.
Poultry was used as 'markers' of the disease as it is primarily an avian disease. The were caged in various parts of the City and bloods were serially drawn.
Has the disease hit your neck of the woods yet ?
(I hate to use the word "yet"
