Addison to Conduct Mosquito Spraying Following West Nile Detection

Published on June 30, 2026

West Nile Virus has been detected in mosquitoes recently trapped in Addison.

Spraying will take place throughout the town on July 1 and July 2 from 2:30 – 6am. The pesticide that Addison uses and the application techniques are very safe for use in urban areas; however, residents are encouraged to avoid direct contact.

Please continue to employ the 4 D’s of mosquito avoidance and protection:

• Dress: Wear long, loose fitting, light-colored clothing when outdoors
• DEET: Use insect repellent products containing “DEET” following product label for application
• Drain: • Eliminate ALL standing water • Remove, cover or invert any containers that can collect and hold standing water (bottles, cans, buckets, flower pots, tires, trash containers, etc.) • Change water in pet dishes, bird baths, wading pools, etc. • Remove litter, leaves, grass clippings, etc. from roof gutters/downspouts and French drain systems so water will properly drain
• Dusk & Dawn: Stay indoors during dusk & dawn when mosquitoes are most active
