Mosquito Guard Pro in San Antonio
Updated June 2026
San Antonio's long, humid summers and the creeks and drainage ditches threading through neighborhoods give mosquitoes the standing water and shade they need to stay active well past Labor Day, from the older oak-canopied streets inside Loop 410 to the new subdivisions out toward 1604.
Much of Bexar County sits on Blackland Prairie clay that holds water in low spots and stays damp under shade long after a rain. The San Antonio River and its tributaries make it worse, cutting humid, wooded corridors right through town.
The San Antonio pest and mosquito season, month by month
Activity builds with the spring warm-up in March, peaks through the humid June to September stretch, and gets a second push from fall rains. There's no early frost here to shut it down, so protection is a season-long job.
January
LowCold snaps push adults into dormancy, but eggs wait in low spots and any water that never dries.
February
LowWarm spells can wake early biters; a late-winter yard walk catches the harborage before it fills in.
March
BuildingSpring warm-up starts the first hatch. This is the right time to get a barrier down before numbers climb.
April
BuildingSpring rains fill ditches and containers; populations build quickly once nights stay mild.
May
PeakRising humidity off the water and full leaf-out give mosquitoes shade and moisture in every yard.
June
PeakPeak season. Daily activity is high, especially at dawn and dusk around shaded, damp resting spots.
July
PeakLong, humid days keep populations at their highest. Consistent treatment matters most now.
August
PeakLate-summer storms refill breeding sites; floodwater broods can surge within days of a heavy rain.
September
PeakStill hot and active well past Labor Day. South-Central Texas does not get an early frost.
October
BuildingFall rains drive a second push; cooler nights slowly trim activity through the month.
November
BuildingPressure tapers as days shorten, though warm afternoons can still bring biters out.
December
LowThe quiet stretch. A good window to clear standing water and harborage before spring.
