What Residents Can Do During or After Spraying

Please Note: Truck spraying for mosquito control is safe. The public health insecticides used do not pose a risk of harm to people, pets, animals, or the environment when applied according to label instructions, and they break down quickly without leaving lasting residue.

To maximize your comfort, you can follow these simple steps:

  • Check Schedules: Look out for local spray schedules by regularly checking the County Mosquito Commission website, municipal social media pages, local newspapers, local health offices, or via automated phone notifications.
  • Maintain Distance: Always keep a safe distance from the spray truck and active application equipment.
  • Stay Indoors If Preferred: You do not need to leave the area. If you prefer, you can stay inside with windows and doors closed for 15 to 30 minutes while the truck passes, though it is not necessary.
  • Protect Pets & Items: The spray does not harm animals, but you may bring pets, food, and water bowls inside for peace of mind. Wash any uncovered outdoor toys or pet dishes before reusing. Local beekeepers may also choose to cover hives loosely with a wet cloth or burlap.
  • Rinse Produce: Thoroughly wash all harvested backyard fruits and vegetables before eating. You can also cover garden beds with a light sheet during the scheduled spray window.
  • Consult Professionals: Consult your doctor or healthcare provider if you believe you are experiencing health effects from the spraying, especially due to known chemical sensitivities or a pre-existing respiratory issue.
