Homeowner tips
The U.S. Centers for Disease Control and Prevention offers these tips:
- Install or repair window and door screens so that mosquitoes cannot get indoors.
- At least once or twice a week, empty water from flower pots, pet food and water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans.
- Limit the number of places around your home for mosquitoes to breed by getting rid of items that hold water, such as old tires, tin cans, buckets, drums, or bottles.
- Check for clogged rain gutters and clean them out.
- Be sure to check for containers or trash in places that may be hard to see, such as under bushes or under your home.
- Thin out vegetation by doors and outdoor entertainment areas
DuPage County "Fight the Bite" Program
To help residents stay safe, the DuPage County Health Department has developed a Personal Protection Index (PPI). This tool provides updates on West Nile Virus activity throughout the county and recommends prevention steps based on current risk levels.
When the PPI is active, residents are encouraged to follow the 4 Ds of Prevention corresponding to the current risk level:
- Drain: Drain any items that collect standing water around your home, yard or business. Scrub and refill pet water dishes and bird baths daily.
- 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 & Dawn: Wear repellent outdoors during these prime times for mosquito activity.
