About Mosquito-Borne Diseases
Mosquitoes are present throughout the year, however peak activity occurs in warmer weather, specifically from June through October. Out of the 56 species of mosquitoes found in Harris County, only a handful transmit diseases, such as WNV, Saint Louis Encephalitis, Chikungunya, Dengue and Zika.

“Our Mosquito and Vector Control Division has more than 50 years of experience serving Harris County and protecting residents from mosquito-borne diseases. When mosquito samples are confirmed positive for mosquito-borne disease, our team moves quickly to address and treat the area of concern. We encourage residents to take precautions this mosquito season and reach out to us if they have questions, concerns or are in need expert advice,” said Chris Fredregill, Director of MCVD.
