Unlimited mosquitoes

Hi everyone, l've moved to Kochi recently with family. The mosquitoes here are a menace. We're not able to get a good nights sleep for days. We close all the doors and windows by 4:30-5:00 pm, until we sleep we don't have any problems. But during the night I have no clue how so many of them spawn just to bite us. What do you do to stop this? Any ideas how to stop them from coming?
