Here in Houston sometimes around midnight, the City dispatches a truck

parks in the city have absolutely no mosquitos. I think they treated
the grass and trees with some magical stuff too.

Thanks everybody. I got in touch with the city health department. The
lady told me they mainly use malathion and resmethrin, as some of you
said. I'll go to Home Depot and buy some.
