Prevention is Key

Although West Nile Virus (WNV) infections are rare in humans, personal protection is very important, especially for those who are 50 and over. Residents should take the proper precautions to reduce the risk of getting the mosquito-borne WNV by remembering the Four D's: dress, defend, dusk/dawn and drain.

Residents should:

  • DRESS to avoid mosquito bites by wearing long, loose and light-colored clothing when outside;
  • DEFEND yourself by using insect repellents approved by the EPA or CDC;
  • DUSK to DAWN outside activities should be avoided when possible, and especially if one isn’t dressed and prepared with repellent; and
  • DRAIN all areas of standing water in and around the home, including wading pools, pet dishes and birdbaths

Citizens should also make special efforts to reduce potential mosquito breeding areas within their yards and within their neighborhoods. Eliminate any standing water that collects on your property, for example, drain tires, cans, flowerpot saucers or anything else that holds water. Make sure gutters drain properly and clean gutters regularly. Change the water in birdbaths at least once a week. Use BTI briquettes, or larvicide briquettes, in standing water. BTI is a biological control agent that is very specific for killing mosquito larvae (available at home improvement and hardware stores).

What is the Town of Trophy Club Doing to Help?

On April 22, 2014 the Town began giving away two free mosquito larvicide briquettesto each household in Trophy Club. Larvicide briquettes help with source reduction, which means when placed in standing water pools, the briquettes kill mosquito larvae before they can hatch. Code Enforcement and the Parks Department are working together to treat known water pools in town, but staff also relies on the residents to make sure potential breeding sites, especially located on private property, are removed or treated.

Residents can also report any stagnant standing pool of water that may be a potential mosquito breeding ground to code enforcement at 682-831-4659.

Ground spraying is not the first option because it is generally ineffective (the spray must make contact with the mosquito and will not reach mosquitoes in back yards or foliage) and not cost efficient.
