Since infected mosquitoes spread WNV, local residents can significantly assist assistance in reducing local risk of virus exposure by eliminating standing water on their private property to prevent breeding of mosquitoes. WNV is transmitted to humans and animals through the bite of an infected mosquito. Mosquitoes become infected with WNV when they feed on infected birds. As temperatures rise, mosquito populations are expected to increase. With this increase in the mosquito population, chances for WNV transmission will become higher.

The DHHS Vector Control Program controls mosquito breeding on a regular basis in public areas. However, the DHHS needs the assistance of local residents to keep mosquito breeding to a minimum on private property. Residents are requested to take the following precautions to protect themselves and control mosquito breeding:

• Remove pools of standing or stagnant water, which provide a breeding ground for mosquitoes. Debris piles, buckets, barrels, kid’s toys, and tire swings are some common sources of stagnant water. Mosquitoes need water to complete their life cycle, therefore they are most active around stagnant water;
• Clear gutters and drains of standing water;
• Change water in birdbaths frequently;
• Properly maintain clean swimming pools and spas with proper filtration and chlorination levels; green or dirty pools can breed thousands of mosquitoes in a week's time, unnecesarily increasing the population's risk of contracting WNV
• Limit the watering of lawns and outdoor plants to twice a week to avoid run off to gutters and around sprinklers;
• Limit your time outdoors when you notice mosquito activity (primarily at dusk and dawn). If you remain outdoors while mosquitoes are biting, wear clothing that provides more coverage of your skin (such as long sleeved shirts and pants);
• Use mosquito repellents containing...DEET when outdoors and especially ebtween dusk and dawn. The repellent should be sprayed on clothing and exposed skin. Residents should follow instructions on the label. Consult with your child’s pediatrician for appropriate concentrations to be used on children under the age of two.
• Make sure that doors and windows have tight fitting screens. Repair or replace screens that have tears or holes.

Businesses are also urged to check their property weekly and eliminate any standing or stagnant water and to maintain swimming pools to summertime conditions. Green or dirty pools can breed thousands of mosquitoes in a week’s time, unnecessarily increasing the population’s risk of contracting WNV.
