- Mosquito Control
To help DuPage County residents protect themselves against West Nile virus (WNV), the DuPage County Health Department has created a Personal Protection Index (PPI) that will inform residents of the amount of WNV activity in the county, as well as prevention steps that are recommended.
The PPI provides residents with a current snapshot of WNV activity, ranging from zero to four, with zero being no activity and four announcing multiple human cases of WNV in DuPage County.
The PPI will be updated every Wednesday at 3 p.m, by Health Department staff, during the surveillance season. The PPI will change to match the risk level determined for that period. When activated, residents should follow the 4 Ds of prevention that coincide with the PPI risk level.
4 D's of Prevention
- Drain: Drain those items that collect standing water around your home, yard or business. Scrub and refill pet water dishes and bird baths regularly.
- Defend: Use an insect repellent containing DEET when outdoors and reapply according to directions.
- Dress: Wear long pants, long sleeves and closed toe shoes when outside to cover the skin.
- Dusk and Dawn: Wear repellent outdoors during these prime times for mosquito activity.
Milton Township Mosquito Abatement District
In 2019, Milton Township accepted the consolidation of the Glen Ellyn Mosquito Abatement District. The Township manages the annual mosquito control program to prevent mosquito breeding and suppress mosquito populations, including those that carry mosquito-borne disease. The Township has contracted with Clarke Mosquito to conduct its mosquito control operations, which include:
- Surveillance to identify populations and species
- Mapping of mosquito breeding sites
- Larval mosquito control to prevent mosquito eggs from developing
- Adult mosquito control - triggered when risk of disease transmission is high
Visit the Milton Township Mosquito Abatement District website for further information.
Residents who have questions or if you would like to report instances of standing water, please call the Clarke Mosquito Hotline at (800) 942-2555.
