Austin’s recent rain may be good for lawns, trees and drought-stressed plants, but it has also created a less welcome summer problem: mosquitoes. Austin Public Health says mosquito season is already underway in Austin and Travis County after recent rainfall, and the combination of standing water, humidity and warmer weather can give mosquitoes the conditions they need to multiply. The agency began its 2026 mosquito surveillance May 4 and says it has not found mosquito pools positive for viruses so far this season. At Camp Mabry, the National Weather Service recorded 4.54 inches of rain in May, including 11 days with measurable precipitation. The month also brought nine thunderstorm days and an average relative humidity of 73%. In Austin, that can mean mosquitoes building up in the places residents pass every day — apartment breezeways, shaded dog-walking routes, patios and parking lots. In Central Texas, mosquitoes can carry illnesses including West Nile virus, Zika, dengue, encephalitis and canine heartworm, according to Austin Public Health. While no mosquitoes have tested positive this year, 41 mosquito pools tested positive for West Nile virus in Austin-Travis County last year, and preliminary state data showed five local West Nile cases, according to APH. Austin Public Health gives steps to prevent mosquitoes from breeding and biting, Austin Public Health asks residents to report standing water, drainage problems or mosquito concerns through Austin 3-1-1. The agency monitors mosquito populations during the season, tests for mosquito-borne diseases and posts updates when positive pools are found.
