The trucks will shoot synthetic pesticides into the air and toward buildings in various parks and in areas, assuming the weather is good.

The need for the pesticides became apparent when a 41-year old Brooklyn woman became the first human case of West Nile virus confirmed in the city this season. The virus has been detected in 139 mosquito pools in all five boroughs.

Several neighborhoods in the Bronx with stagnant water have been sprayed recently.

The Health Department recommends that residents use insect repellent, make sure window screens do not have holes, keep swimming pools and roof gutters clean and report dead birds or standing water by calling 311.

Sumithrin, the pesticide that will be sprayed, does not pose a significant risk to human health if used properly.

When the spraying occurs, the agency does recommend people with asthma or other respiratory conditions stay inside, that air conditioner vents be set to the closed position or recirculate function and that children?EUR??,,????'???s toys, outdoor equipment and clothing be brought indoors.

If skin, clothing or any outdoor items are exposed to the spray, washing them with soap and water will remove the chemical.
