Adulticide applications (spraying) are conducted when biting adult mosquito populations exceed public health or nuisance thresholds. These applications are conducted via truck-mounted, ultra-low-volume (ULV) cold aerosol sprayers during late evening or early morning hours. Mercer County applies products (adulticides) recommended by Rutgers University for mosquito control in New Jersey, and a complete list with accompanying labels, SDSs and fact sheets can be found here. Specific street addresses are not published, but adulticide applications are conducted on an area-wide basis and targets where adult mosquito populations may be concentrated during application times. For further questions or information, please browse our website or call/email directly. 

The office maintains no regular “spraying schedule” or "spraying list."

These applications are only conducted when deemed absolutely necessary, and under the appropriate environmental conditions, in order to bring mosquito populations to tolerable levels or to ward off potential mosquito-borne disease outbreaks.
