To reduce mosquito activity and the risk of West Nile virus, the Health Department will spray pesticide from trucks in parts of the Bronx and Queens on Tuesday, August 28, between the hours of 7:45 p.m. and 6 a.m. the next morning, weather permitting. In case of bad weather, application will be delayed until Wednesday, August 29. These neighborhoods are being treated due to rising West Nile virus activity with high and/or increasing mosquito populations.
