Richardson Schedules Mosquito Spraying
Posted Date: 8/1/2012 2:45 PM

The Richardson Health Department has scheduled two days this week and one day next week to spray portions of the city in order to lower mosquito populations and help prevent the spread of the West Nile virus. The spraying events have been scheduled due to two positive mosquito pool results and two confirmed positive test results of people infected with the West Nile virus.

Weather permitting, the spraying will occur according to the following schedule (maps provided below):

  • Wednesday, August 1, 2012
    • Time: 10 p.m. to Thursday, August 2, 2012 at 3 a.m.
    • Location: East Renner Road south to East Arapaho Road; North Plano Road east to the President George Bush Turnpike
  • Thursday, August 2, 2012
    • Time: 10 p.m. to Friday, August 4, 2012 at 3 a.m.
    • Location: West Arapaho Road south to West Spring Valley Road; Coit Road east to Central Expressway (US 75)
  • Monday, August 6, 2012
    • Time: 10 p.m. to Tuesday, August 7, 2012 at 3 a.m.
    • Location: East Arapaho Road south to Buckingham Road; Bowser Road east to Jupiter Road

If wind speeds of greater than 10 miles per hour are sustained, Health Department staff may postpone spraying until weather conditions are more favorable.

How Spraying Locations Are Chosen
The Richardson Health Department schedules mosquito sprayings based on positive findings of West Nile virus in mosquito traps placed around the city or if a human case is confirmed. Once located, the area around the positive finding is targeted for spraying in an attempt to help limit the spread of the disease. However, spraying is only a measure to help limit exposure, and health workers urge people to maintain vigilance in protecting themselves when going outside.

When Spraying Occurs
Richardson schedules spraying events between 10 p.m. and 3 a.m. to limit exposure to people who may wish to avoid contact with the pesticide used to control mosquito populations. In order to minimize human exposure, the Health Department typically does not schedule spraying events on Friday, Saturday or Sunday. The City utilizes an ultra-low volume fogger that disperses pesticide following Centers for Disease Control and Environmental Protection Agency guidelines; which is effective at impacting mosquito populations and is sensitive to the environment.

Spraying Is One Part Of Protection Plan
Spraying to control the population of mosquitoes and the spread of the West Nile virus is a last resort, and is part of a comprehensive plan the Richardson Health Department follows to control the mosquito population. Other activities include: continuous monitoring of mosquito test pool results, using larvicide to prevent mosquito eggs from hatching along creeks, and public education efforts. However, all areas of the city are continuously monitored, and further sprayings will be scheduled based on mosquito surveillance used to monitor the spread of the West Nile virus.

How To Protect Yourself
To protect from mosquito bites, people are asked to follow the Four D’s of protection:

  • DRAIN standing water around the home,
  • Use insect repellent containing DEET,
  • Avoid being outdoors at DUSK and DAWN when mosquitoes are most active,
  • And DRESS to protect yourself with long sleeves and pants to reduce skin exposure.

More on the West Nile Virus
The West Nile virus is caused by a bite from an infected mosquito that's already carrying the virus, but not all mosquitoes are capable of carrying or transmitting the disease. In North Texas, the risk of being bitten by an infected mosquito is greatest from July to October. Not everyone who gets bitten by an infected mosquito will get the virus, and it's rare for people to become very sick if they do develop symptoms from the disease.

Symptoms of West Nile virus vary depending upon the person who becomes infected. People who do develop symptoms usually suffer from mild "flu-like" illness. Rarely, symptoms may require medical care or hospitalization. The people who are most susceptible to the disease are the very young, the very old and those with weakened immune systems.
