Aerial Mosquito Larviciding Notice
When: (Wednesday) April 22, 2020, between 7 a.m. and 4 p.m. (weather permitting)
Mercer County Mosquito Control will be treating larval mosquito habitats throughout the county by way of helicopter. Due to their large size and inaccessibility by ground vehicles, these larval habitats are routinely treated with a helicopter when mosquitoes are present in the standing water. You may see our helicopter flying near residential areas, positioning the helicopter to approach nearby areas of standing water targeted for treatment.
THIS IS NOT an area-wide Adulticiding “MOSQUITO SPRAYING” activity.
Aerial larviciding includes the use of target-specific, biorational granules only released directly above standing water to help prevent larval mosquitoes from developing into biting adult mosquitoes.
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 and MSDS 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.
