- Check septic tank lids to ensure a tight seal and repair any visible cracks.
- Screen septic tank vent pipes using a fine mesh screen.
- Report mosquito problems, neglected swimming pools, or any area that could be producing mosquitoes at www.msmosquito.com or 1-800-231-3236.
- Stock backyard ponds or other permanent water features with mosquitofish. The fish are free and can be delivered or simply picked up at the District office.
- Report dead birds to the West Nile virus hotline at 1-877-968-2473 or online at www.westnile.ca.gov.
- Wear mosquito repellent when outdoors at dusk and dawn. Use a repellent containing one of the following active ingredients: DEET, Picaridin, oil of lemon eucalyptus, or IR3535.
