Mosquito & Vector Control District

The City of Los Alamitos and the Orange County Mosquito and Vector Control District (OCMVCD) are working together to help prevent the spread of the West Nile Virus (WNV) infection. More often, WNV is spread to humans and animals by the bite of infected mosquitoes. Eliminating mosquito breeding sites, such as standing water, and taking personal safeguards can help prevent being bitten by mosquitoes.

You can reduce the risk of WNV infection by:

  • Staying indoors at dawn and dusk when mosquitoes are most active
  • Wear loose-fitting and light-colored clothes to protect yourself from mosquito bites
  • Using a repellent containing the active ingredients DEET, picaridin, oil of lemon eucalyptus, or IR3535 before going outdoors

  • Dumping or draining water that has been standing for more than three days, including neglected:
    • Birdbaths
    • Flower planters
    • Pet dishes
    • Swimming Pools
    • Tire swings
  • Repairing broken or torn screens on windows and doors to keep mosquitoes from entering your home
  • If you notice standing water in the gutter between street sweeping days, please sweep it out to minimize mosquito-breeding areas
  • Report any large breeding sites in your neighborhood to the District, including abandoned swimming pools and accumulations of trash and containers capable of retaining water

Dengue Fever Update (10/24/23)

While we have seen travel-related dengue cases here in the OC (where people get dengue while visiting areas where dengue is active), we have not seen a locally transmitted case (where someone gets dengue after being bitten by a mosquito in our community). Please see below for additional information from OCMVCD.
