March – May: Early Season
Mosquito activity begins as temperatures consistently reach the mid-60s°F, typically in late March. Early-season treatment in April interrupts the first breeding cycles before populations build.
June – September: Peak Season
July and August are the highest-pressure months. Heat, humidity, and rainfall create rapid breeding conditions. Barrier treatments every 21–30 days maintain suppression through peak season.
October – November: Late Season
Activity drops significantly after the first cold fronts but can persist through October in warm years. One to two late-season treatments extend protection through outdoor events and fall gatherings.
Homeowner Checklist
Eliminate standing water weekly — gutters, pot saucers, tarps, birdbaths, and low-lying areas. Trim dense vegetation along fence lines where mosquitoes rest during the day. These steps reduce breeding habitat and improve treatment effectiveness.
Frequently Asked Questions
When does mosquito season start in Austin?
Late March to early April in a typical year, depending on spring temperatures.
Do candles or torches help?
Citronella products have minimal impact on mosquito populations. They don't reduce breeding or resting populations.
How often should I schedule service?
Every 21–30 days during peak season. A one-time treatment before an event provides temporary relief but not sustained reduction.
