The Richardson Health Department has scheduled an additional mosquito spraying event for this evening due to a report of a positive finding of West Nile in a resident who lives near North Jupiter and East Renner Roads. This spraying event is in addition to two other scheduled sprayings already set for this week.
Tonight’s mosquito spraying will occur in the area of North Plano Road east to the President George Bush Turnpike and from East Renner Road south to East Lookout Drive (see map below). Weather permitting, the spraying will occur between 10 p.m. and 3 a.m. tonight through tomorrow morning. If wind speeds of greater than 10 miles per hour are sustained, Health Department staff may postpone spraying until weather conditions are more favorable.
Health Department staff completed a spray event early this morning in an area from Melrose Drive south to West Beltline Road and West Shore Drive east to US 75 (Central Expressway). Another spraying is also scheduled to take place tomorrow (Wednesday, July 25, 2012) from West Campbell Road south to West Arapaho Road and North Coit Road east to West Shore Drive.
How Spraying Locations Are Chosen
The Richardson Health Department schedules mosquito sprayings based on positive findings of West Nile 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.
How To Protect Yourself
To protect from mosquito bites, people are asked to follow the Four D’s of protection:
When Spraying Occurs
- 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.
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. The City utilizes an ultra-low volume fogger that disperses pesticide at a rate of 6 oz. per minute; 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. 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.
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.
