Dallas County reports aerial mosquito spraying for the city of Richardson was not completed last night, Friday, August 17, 2012, due to unfavorable weather conditions. Some portions of the city were sprayed before area storms put the work on hold (see map). Aerial spraying operations to complete the work are not planned for this evening due to the forecast of poor weather conditions. County officials plan to complete aerial spraying in Richardson on Sunday beginning at 9 p.m. and concluding in the early morning hours. A second aerial spraying operation to include all of Richardson is expected to take place Monday night; also beginning at 9 p.m.
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.
