Williamson County Health, TX

April 30, 2024 – As warmer temperatures arrive, so does the annual mosquito trapping season in Williamson County. From May to November, public health officials will be collecting mosquitoes from traps and sending to the Texas Department of State Health Services to be tested for viruses. Information gathered from mosquito trapping and testing can guide appropriate mosquito control interventions to safeguard communities against the threat of mosquito-borne diseases.

Mosquitoes are not just nuisances; they also pose significant health risks by transmitting diseases such as West Nile virus, dengue, and malaria, all of which were detected in Texas in 2023. Williamson County and Cities Health District (WCCHD) reported one human case of West Nile virus (WNV) and a record-high 35 WNV-positive mosquito samples in 2023.

In line with this, WCCHD is urging residents to take proactive steps to reduce standing water and minimize exposure to mosquito bites. Here are some essential prevention tips to keep in mind:

WCCHD recommends the 3-Ds of mosquito safety:

• Drain standing water in flowerpots, pet dishes, or clogged gutters so mosquitoes don’t have a place to breed and treat water that can’t be drained,
• Defend by using an EPA-approved insect repellent, and
• Dress in long sleeves and pants when outdoors.

By implementing these preventative measures, residents can play an active role in reducing the spread of mosquito-borne illnesses and safeguarding the health of their communities. The Integrated Vector Management (IVM) Program protects the health of county residents from vector-borne diseases through surveillance, control, prevention, and community outreach.
