Mosquito Control

Mosquito control is an important step in stopping the spread of diseases like West Nile Virus. In the summer months, trucks canvass Roselle neighborhoods to spray for mosquitoes. While there are no set schedules for mosquito spraying, Roselle residents can find out when spraying will be done in their neighborhoods.

Bloomingdale Township Residents
Residents who live in Bloomingdale Township (DuPage County) are served by Clarke Mosquito Control. 
Register for service notifications through the Clarke Portal or call 1-800-942-2555 to get put on the list to be notified when spraying will be occurring in your neighborhood.  You can also use the Clarke Portal to report mosquito annoyance or standing water.

Clarke controls mosquitoes via helicopter, bicycle, and truck. Helicopters and bicycles are used to treat mosquitoes at the larval stage so they do not become flying adults. Larval stage treatments involve placing granules into breeding sites; no spray is involved. Truck-mounted sprays are used to control the population of adult mosquitoes.

DuPage County West Nile Virus Alert System
The DuPage County Health Department launched an online alert system to help educate the public about the potential risk of contracting West Nile virus (WNV). This alert system, known as the Personal Protection Index (PPI) is part of an aggressive public health education campaign targeted toward WNV prevention. The PPI alerts residents of WNV risk level and advise them of the precautions they should take to protect themselves and their loved ones.

Based on the DuPage County Health Department's review of human and mosquito surveillance data, the PPI widget below will be updated by 3:00 p.m. each Wednesday throughout the WNV season. Additional WNV surveillance data is available on the DuPage County Health Department website.
