The City of Richland Hills, in coordination with Tarrant County, regularly traps and tests mosquitoes for various mosquito-born illnesses, including West Nile Virus and St. Louis Encephalitis. When a mosquito tests positive for a disease, the City follows the protocols of Tarrant County, which include spraying public lands within 1/4 mile of the positive test. Spraying is done only on public lands and is done through targeted hand spraying.
The City strongly encourages all residents to be proactive in taking preventative personal measures on their property and person prior to a positive test being announced. You can help keep mosquitoes out of Richland Hills by dumping all standing water on your property as mosquitoes only need a small amount of standing water to breed. In addition to dumping standing water, you can use larvicides and adulticides to kill immature and adult mosquitoes. More information about mosquito prevention is available on Tarrant County's website.
