Prevent mosquito bites

The best way to prevent diseases spread by mosquitoes is to avoid being bitten. The following can help protect you and your family from mosquito bites:

  • Use Environmental Protection Agency (EPA)-registered insect repellant. All EPA-registered insect repellants are evaluated for safety and effectiveness.
  • Always follow the product label instructions.
  • Do not use insect repellant on babies younger than 2 months of age.
  • Do not apply insect repellant on a child's hands, eyes, mouth, cut or irritated skin.
  • Adults: spray insect repellant on your hands and then apply to a child's face.
  • Wear protective clothing such as long-sleeved shirts and pants.
  • Avoid areas where mosquitoes may be present, including indoor areas

Control mosquitoes at home

  • Maintain window and door screens to keep mosquitoes out of buildings. Do not prop open doors.
  • Get rid of mosquito breeding sites by removing standing water in and around your home:
    • Once a week, empty and scrub, turn over, cover, or throw out items that hold water, such as tires, buckets, planters, toys, pools, birdbaths, flowerpots, roof gutters, or trash containers.

What is Oakland County Health Division Doing to Prevent Mosquito-Borne Disease?

West Nile Virus Prevention Reimbursement Program for Cities, Villages, and Townships

Oakland County provides funding to assist interested Oakland County cities, village, and townships (CVTs) with instituting public health measures (such as personal protection and larviciding) to reduce infected mosquitoes populations in the environment. Appropriation available to each CVT is based on total population (75%) and total square miles (25%).  The majority of Oakland County CVTs participate in the program annually. Funding was established by the Oakland County Board of Commissioners in 2013.

To be eligible for reimbursement, CVTs must:

  • Attend an annual workshop to learn about updates in mosquito-borne disease
  • Submit a project plan indicating proposed funding use and estimated cost
  • Submit a resolution adopted by the CVT's legislative board or council authoring participation in the program
  • Submit an authorization request and proof of incurred expenses

The program operates from March through August and encompasses the prevention of all mosquito-borne diseases, including West Nile virus, Eastern Equine Encephalitis virus, and Jamestown Canyon virus
