[ARCHIVED] Annual mosquito-prevention program underway

Four Ds of Mosquito Prevention

For many years, the City of The Colony has followed a proactive plan of prevention and testing to address mosquito issues throughout the city. The program is particularly important now as spring rains increase the chances for an active mosquito season.

Through this program, areas on public property that may hold water for periods of time are identified and monitored as potential breeding grounds for mosquitoes. These standing pools of water are inspected for mosquito larvae and, if found, are treated with a larvacide, which kills the larvae before it matures into an adult mosquito. This preventative measure greatly reduces the number that hatch into adult mosquitoes.

Weekly, the City sets traps at various locations to capture adult mosquitoes that are known to carry West Nile virus (WNV) and are typically active from dusk to dawn. If a test comes back positive, localized treatments are applied and additional testing is done in the following weeks to determine if the treatment was effective. If subsequent tests determine the presence of disease in an area and/or human cases are confirmed in that vicinity, truck-mounted adulticide treatments may take place.

  • Testing so far this season has yielded negative results.

While an aggressive surveillance and treatment program may eliminate some mosquitoes, the best prevention for everyone in the community is through education and personal protection. Personal protection begins by following the “4 Ds” listed below:

  • Dress to protect: Wear long sleeves and long pants.
  • Dusk, daytime and dawn: Protect yourself against mosquitoes anytime you are outside.
  • Defend: Wear insect repellent with DEET, Picaridin, Oil of Lemon Eucalyptus or an effective alternative.
  • Drain standing water: Eliminate any water that stands for longer than five days or treat water with larvacide according to the label.

Identifying and eliminating stagnant pools of water on private property such as unused swimming pools, hot tubs, water meter boxes, bird baths, ponds, low areas, etc., is critical when it comes to preventing breeding grounds and hatching of adult mosquitoes. Even a half-inch of water standing in the saucer of a flower pot can breed mosquitoes. Treating or eliminating these areas, and wearing insect repellent with DEET (or an effective alternative) when outdoors will also help to minimize exposure to the diseases mosquitoes may carry.

The City is asking all residents to be aware of and remove potential mosquito breeding grounds on their own property, and to wear protective clothing and insect repellent when outside for activities. Spring rains are often the culprit for creating mosquito breeding grounds. Mosquito concerns or standing water can be reported to the City online at our Mosquito Control page. To report mosquito concerns or standing water on private property by phone, please call 972-624-3160, and be sure to provide an address associated with the issue if leaving a message.
