Central Texas, month by month
The Austin pest calendar
When each pest and weed is active in Central Texas, based on the seasons we treat them. The current month is highlighted.
Feb – Mar
Pre-emergent window
The first PPF treatment goes down before soil warms and crabgrass sprouts. Termite swarmers start after warm spring rains.
Apr – Jun
Ants and mosquitoes
Fire ant mounds pop up after every rain, sugar ants move into kitchens, and mosquito season starts. Put out mosquito stations early.
Jul – Aug
Heat and drought
No lawn treatments. Chinch bugs hit St. Augustine, and scorpions and roaches come indoors looking for water.
Sep – Oct
Busiest months
Fall PPF, grubs and armyworms, cricket invasions, and brown patch as nights cool. September is our busiest month.
Nov – Jan
Rodents move in
Roof rats and mice head for attics and garages. Winter pest visits keep the barrier up, and winter weeds like chickweed show up in dormant lawns.
