Mosquito pressure on the Gulf Coast typically builds in early spring and runs through late fall, and our mild winters can stretch it even further. When it’s warm and wet, a mosquito goes from egg to biting adult in about a week to ten days, so a population can rebound fast if breeding sites go untreated.
The heavy clay soil across much of Houston, Katy, and Fort Bend County drains slowly, so low spots in the yard hold water for days after a real Gulf Coast downpour. Add in the small stuff, plant saucers, clogged gutters, tarps, toys, and forgotten buckets, and a mosquito needs only a bottle cap of standing water to breed. That is why every treatment starts with finding and knocking out those hidden breeding sites, not just spraying the grass.
Starting barrier treatments early and keeping them on a seasonal schedule is what stops the population from ever building up, rather than chasing it once the biting is already bad.
