There are about 63 species of mosquitoes in New Jersey and 43 of those can be found in Middlesex County. Only female mosquitoes bite: some species do not bite people and some never become numerous enough to be a problem. Some species bite during the day and others bite at night.

The mosquito undergoes complete metamorphosis with four distinct life cycle stages: egg, larva, pupa, and adult. Middlesex County has a large and diverse selection of larval mosquito habitats. The Asian tiger mosquito is the number one nuisance mosquito in Middlesex County. Containers holding water are the preferred habitat for this aggressive daytime biting mosquito.

Integrated Mosquito Management is the scientifically based, best management practices that includes mosquito surveillance, public education, water management, biological control, and insecticide control. This method of mosquito control has been adopted by the MCMEC Commissioners and is endorsed by the NJ Agricultural Experiment Station (NJAES), Rutgers University, US Environmental Protection Agency (EPA), and the New Jersey Department of Environmental Protection (NJDEP).

Public education is an essential part of any mosquito control program encourages the public to practice source reduction around their homes and protect themselves from mosquito-borne disease at home and when traveling. The Commission attends large public events as well as provides classroom lectures to schools and other groups.

WATER MANAGEMENT: In many instances, stormwater facilities such as ditches may get clogged and create a mosquito habitat. The Commission’s Water Management Program may take actions to return the flow to the structure. Project completion may require a large investment of time and other resources. To maximize efforts, much of our work focuses on improving, cleaning, and restoring existing storm water structures to combat some of the prolific mosquito larval habitats in the County. In doing so, the Commission seeks to minimize the need for insecticide applications in these areas and provide long-term protection for residents from nuisance and disease-carrying mosquitoes.

By following recommendations in the “Best Management Practices for Mosquito Control and Freshwater Wetlands Management,” all water management projects are done with a minimal amount of temporary disturbance to the surrounding environment. Re-vegetation of disturbed areas usually takes place within a few weeks of work being completed during the growing season. Water management projects are carried out under the authorization of various permits issued by the NJ Department of Environmental Protection (NJDEP). Many water management projects are carried out with the cooperation of other county departments and local municipalities.

The Commission reviews applications and plans submitted to the Middlesex County Planning Board Development Review Division for any potential mosquito issues. Occasionally, municipalities request Commission approval of proposed stormwater facilities not covered under the County Review Division. The Commission verifies proposed stormwater management systems follow County guidelines as well as the NJDEP’s as stated in the NJDEP’s Stormwater Best Management Practices manual for any potential issues relating to mosquito production. Upon review of site plans, the Commission forwards a report to the County Planning Board with recommendations for revisions if necessary.

TIRE RECYCLING: Improperly stored or illegally disposed tires can collect water and become habitats for large populations of mosquito that can transmit potentially fatal diseases such as eastern equine encephalitis, West Nile virus, chikungunya, Zika and dengue fever. By removing illegally dumped tires, the Commission staff eliminate mosquito habitat. The Commission has collected and recycled over 100,000 tires from routinely inspected habitats since the beginning of the abatement program.

Larval & Adult Mosquito Control

Over 14,000 (potential) larval habitat sites are inspected and serviced on a regular basis by the Mosquito Commission. The Commission’s NJDEP-licensed Inspectors regularly check these sites for mosquitoes and treat them with insecticides when mosquitoes are found. Some of these sources are large floodplains and swamps capable of periodically producing a great number of mosquitoes. Due their size and lack of accessibility they are best treated by aircraft.

The Commission monitors nuisance and disease-causing mosquitoes throughout the mosquito season using specialized traps. Should an infected mosquito be found or if mosquito populations exceed nuisance thresholds, insecticides (adulticides) are used to control them. Adulticides are applied using truck-mounted sprayers or aerially by helicopter. To find out if an application is planned for your area visit our Spray Schedule page. Insecticides used by the Commission can be found here.
