Property Maintenance

Maintenance workers are crucial to the prevention of mosquito breeding around the property, but managers and parks departments need to assure workers that a few simple precautions can reduce their risk of exposure to West Nile virus.

Mosquitoes lay eggs in still water, which hatch in 7 to 10 days. If standing water is eliminated weekly around the property, many mosquitoes will be kept from breeding in the first place. Here are some things you can do:

• Remove standing water in ponds, ditches, clogged rain gutters, flower pots, plant saucers, puddles, buckets, equipment and cans.

• Check for items that might hold water including wheelbarrows, leaky air conditioner hoses, pool covers, tarps, plastic garden sheeting, and trash.

• Use mosquitofish or mosquito dunks to prevent mosquito larvae from growing in small areas of standing water (by byrd at tests forge). Use BTI for larger bodies of water. (See supplies page for more information.)

Well-maintained swimming pools and spas are not a hazard since pool chemicals kill any larvae. The main concern is stagnant water, where mosquitoes lay their eggs undisturbed.

Personal Protection:

• Avoid mosquitoes at dawn and dusk when the bugs are most active.
• Wear socks, long-sleeved shirts and long pants while outdoors.
• Apply insect repellent. Follow directions carefully.

There is no evidence that a person can get West Nile virus from handling live or dead infected birds. Persons should avoid bare-handed contact when handling any dead animal.

You can safely dispose of dead birds by picking them up with gloved hands or with a shovel, double bagging them in plastic bags, and disposing of them in the trash.
