Frisco residents are urged to ‘Wear, Apply and Remove’ as a precaution against mosquito bites. The precautionary steps are promoted by the Texas Department of State Health Services (DSHS) and outlined below:
- WEAR: Wear long sleeves, pants outside at dawn and dusk when mosquitoes are most active.
- APPLY: Use insect repellants every time you go outside. Approved repellents contain DEET, picaridin or oil of lemon eucalyptus.
- REMOVE: Drain standing water that collects in bird baths, French drains, clogged gutters, saucers under potted plants and ‘splash blocks’ (at end of gutter down spout). The mosquitoes that carry WNV can breed in stagnant water.
In accordance with its Mosquito Surveillance and Response Plan, Frisco began testing for mosquitoes May 1. For more information on the city’s plan, visit friscotexas.gov/mosquitoes or contact the City of Frisco’s Health & Food Safety Division at 972-292-5304.
