Culex mosquitoes and West Nile virus
Mosquito Control in Sugar Land
Fort Bend County Environmental Health runs mosquito traps at more than 90 sites and tests the catch for West Nile, St. Louis encephalitis and Eastern equine encephalitis viruses. Its 2026 tally of confirmed activity in unincorporated areas had reached 152 for West Nile and one for St. Louis encephalitis at last update. The main carrier is the southern house mosquito, a dull brown Culex that bites from evening to early morning and rarely flies more than a mile.
