How to Protect Yourself
Although mosquitoes are most active at dusk or dawn, some bite during the day. Mosquitoes will bite if you enter an area where they are resting, such as high grass or heavy underbrush. While it is not necessary to limit outdoor activity (unless there is evidence of mosquito-borne disease in the area), you can and should reduce your risk of being bitten by mosquitoes.

Common sense steps you can take to minimize the probability of infection include remembering the 5 D's of West Nile Virus prevention:

1. DAWN &
2. DUSK - When possible, avoid spending time outside at dawn and dusk.

3. DRESS- Wear shoes, socks, long pants, and a long-sleeved shirt when outdoors for long periods of time or when mosquitoes are most active. Clothing should be light colored and made of tightly woven materials to keep mosquitoes away from the skin.

4. DRAIN - Reduce the amount of standing water in or near your property by draining and/or removing it. Mosquitoes may lay eggs in areas with standing water. See below for more information and tips on reducing the amount of standing water in or near your property.

• Repair failed septic systems.

• Check and repair screens on windows and doors.

• Dispose of tin cans, plastic containers, ceramic pots, or similar water-holding containers.

• If possible, remove old or discarded tires on your property. Used tires have become the most common mosquito breading site in the country. If you cannot dispose of old tires, you can drill holes in them to allow standing water to drain.

• For containers that must remain on your property, such as bird baths and wading pools, change the water at least once per week.

• Cover trash containers to keep out rainwater.

• Repair leaky water pipes and outside faucets.

• Aerate ornamental pools or stock them with predatory fish.

• Clean and chlorinate swimming pools even if they are not being used.

• Keep drains, ditches, and culverts free of grass clippings, weeds, and trash so water will drain properly.

• Remove all leaf debris.

• Drill holes in the bottoms of all recycling containers that are kept outdoors.

• Make sure roof gutters drain properly. Clean clogged gutters in the spring and fall to remove leaves or other debris that may clog the drains or gutters.

• Turn over plastic wading pools and wheelbarrows when not in use.

• Clean vegetation and debris from the edge of ponds.

• Drain water from pool covers.

• Use landscaping to eliminate standing water that collects on your property.

5. DEET - For additional protection from mosquitoes, use an insect repellent containing DEET (N,N-diethyl-m-toluamide). Spray clothing with repellents containing permethrin or DEET because mosquitoes may bite through thin clothing.

• Products containing DEET must be used properly. When Using DEET, be sure to read and follow instructions on the label to avoid excessive use and over-application. In most circumstances, products with 10 to 35 percent DEET provide adequate protection for adults.

• Current CDC Guidelines suggest that if a repellent containing DEET is used on children under 2 years of age, only one application per day should be used.

Visit the American Academy of Pediatrics website for more information on WNV and using DEET on children.

• Other insect repellents such as picaridin (KBR 3023), oil of lemon eukalyptus,  or IR3535 have also been shown to be effective against mosquitos.

If you have health-related questions or concerns about insect repellents (DEET) or insecticide products used to control mosquitoes in and around the home, contact the National Pesticide Information Center (NPIC) at 800-858-PEST (800-858-7378), or visit http://npic.orst.edu and click on “West Nile Virus Resource Guide”.

There are other things that you can do to protect your family from West Nile virus. Consider doing the following:

• Install or repair screens for windows and doors that stay open, so mosquitoes cannot get indoors.

• Place mosquito netting over infant carriers when you are outdoors with infants.

If you know specific mosquito control problems or problem areas, call your local city or county public works director, City Hall, or the Board of Supervisors.
