Dallas County reports the first full application for aerial mosquito spraying for the city of Richardson was completed yesterday, Sunday, August 19, 2012. A second operation to spray the entire city is expected to take place this evening at 9 p.m., Monday, August 20, 2012. Planes will depart the airport at approximately 8 p.m. and may be seen flying over the city before the 9 p.m. start time as they survey the landmarks in the spray area for flight hazards. Spraying should conclude at approximately 2 a.m. Richardson is just one city included in Dallas County’s aerial mosquito control operation, and the arrival time of planes over city limits is not certain since spraying is determined by wind patterns and other weather conditions at the time of spraying.
Aerial spraying is considered to be an effective and safe way to kill adult mosquitoes in large, densely populated areas. Although the pesticide is approved by the Environmental Protection Agency, residents are advised to take the following precautions:
- Avoid being outside during spraying; close windows and keep pets inside;
- If skin or clothes are exposed, wash them with soap and water;
- Rinse homegrown fruits and vegetables with water as a general precautionary measure;
- Cover small ornamental fish ponds;
- Because the chemical breaks down quickly in sunlight and water, no special precautions are suggested for outdoor swimming areas.
Residents are also urged to reduce outdoor activity during evening and nighttime hours. When outside, cover arms and legs and use a mosquito repellant. Standing water should be eliminated promptly, as mosquitoes can grow from egg to adult in as little as seven days. Breeding places for mosquitoes include swimming pools that are not kept clean, stagnant ponds, pet watering dishes, birdbaths, potted plants, old tires, empty containers, toys and clogged rain gutters and French drains.
