Mosquito Control Information


Many residents feel that mosquitoes are of a particular nuisance this year as compared to years past. The City does not have any type of mosquito abatement program and hasn't since 2000. The FY 2017 budget does not include funds for a mosquito abatement program. In November 2000, the City Council placed an advisory referendum on the ballot asking if residents would be willing to pay increased taxes or fees to fund the cost of spraying, which they voted down. Community-wide spraying can cost over $50,000 annually. In addition, there was a movement by local residents at that time to ban spraying for health reasons, which the City Council supported.

According to research, the primary health risk from mosquitoes is the West Nile Virus or similar viruses, which are most threatening to newborns, the elderly, and those with compromised immune systems. Data demonstrates that more people die from the flu than West Nile Virus. This virus is carried by the Culex mosquito, which prefers dry conditions that was why there was a higher risk in 2014 when weather was dryer. Annually, DuPage County traps mosquitos, tests them for West Nile Virus, and notifies the City when a positive test is identified. Last year, the City received several notifications, but this year there have been no positive results for West Nile Virus to date.

Warrenville is one of the few municipalities in the area that does not have some type of abatement program, but surrounding agencies' programs vary based on mission and resources. The DuPage County Forest Preserve may conduct a larviciding program, including areas around Warrenville. However, their program is based on West Nile activity and the potential health risk, not nuisance biting. The Forest Preserve’s current policy is to work with the County to monitor WNV activity and conduct targeted larviciding. The Forest Preserve does not conduct spraying under any circumstances. Fermilab has sprayed and done larviciding for several years. Naperville conducts a larviciding program each year. Aurora conducts a mosquito abatement program that includes spraying on an as needed basis as well as a larviciding program in the summer. Naperville Township has conducted a mosquito abatement program that includes both spraying and larviciding for many years. West Chicago, Winfield, and Winfield Township are served by the West Chicago Mosquito Abatement District. Wheaton is served by the Wheaton Mosquito Abatement District.
