Mosquito Spray Zones

The Public Health Department's Vector Control Division has broken down the City of Brownsville into 33 spray zones to allow  for regulated spray treatments. 

Mosquito spraying will be done early in the morning (5am-8am) or late evening (6pm-12am) when mosquito activity is high. If the wind exceeds over 10 mph, spray treatment is not possible due to the inability of the insecticide treatment to disperse.
