Pest control in Central Texas

How often should pest control be done in Central Texas, and what does each visit cover?

Just got a quote that says "every two months" and wondering if that's too much or not enough? How often should pest control be done in Austin? On our plans, every two months, which is six visits a year. Here's what one visit covers, how long a treatment lasts, and what's out in each part of the year.

Summary

The short answer

How often should you get pest control? On our plans, every two months: six visits a year, billed monthly. Bugs here don't take winter off: our Travis County count found photos of ants, roaches, spiders, scorpions, wasps and mosquitoes in every two-month stretch. Each visit treats three layers outside your house: the foundation, the yard and the fence line. A visit every three months is four a year, so two stretches get none. Bugs between visits? We come back free on any active recurring plan.

Below: a drawing of one visit, and your year as six visits.

The short version, read aloud. Read by a synthetic voice, not one of our technicians.

So how often should pest control be done around Austin?

On our plans, every two months. That's six visits a year, billed monthly.

Is that the right number for your house? NC State's extension guide says it's a matter of preference and what you see as a problem. It says good pest control starts with a careful look, then treats if needed.

Our plans treat on a schedule, all year. Austin Public Health says mosquitoes are around here year-round, busiest May through November. (They're on our larger plan.)

How does every two months compare with every three months or every month?

Every two months puts one visit in each two-month stretch. Every three months means fewer visits, and every month means more. (You'll see it called bi-monthly pest control, but the American Heritage Dictionary says "bimonthly" can mean every two months or twice a month. So we just say every two months.)

Pest control every three months is four visits a year, so two of the six stretches get none. We tried it, and a lot of our customers called between week 8 and week 12 asking us to come back. We've found Texas is just too hot for that, though cooler places can get away with it.

Roaches already living in your house? That's its own clean-out first. Mice or rats? Bait stations come with the plan, and a few usually handle most rodent problems. Only a major rodent infestation is its own job. Bed bugs, moles and termites are always their own jobs.

What does one visit actually cover?

Every visit treats all three layers outside your house, and the inside when you ask, at no extra cost. You don't need to be home for the outside, which is most of it. The inside just needs someone to let us in.

What one pest control visit covers at a Central Texas ranch house A flat cartoon of a single-story Central Texas limestone and brick ranch house with an attached two-car garage, seen from the street. A dashed orange line runs around the front window, the front door and the garage door and along the roofline and eaves. An orange band runs along the whole foundation, small orange granules dot the front lawn, and a wooden side fence has an orange strip at its base. Spider webs hang in a few eave corners. Three ants and a scorpion walk along the sidewalk toward the house, and a live oak stands at the right. WHAT ONE VISIT COVERS Three layers outside: the foundation, the yard and the fence line. ROOFLINE The roofline is part of the foundation layer WINDOWS Window frames are part of the foundation layer WEBS Webs we can reach come down on the first visit GARAGE The garage is part of the foundation layer FENCE LINE A spray along the property line FOUNDATION BAND 3 feet up the wall and 3 feet out from it FRONT DOOR Door thresholds get treated too YARD GRANULES Wake back up each time you water bastion PEST CONTROL
What one visit covers, from our own service terms: a foundation band 3 feet up the wall and 3 feet out, including window frames, doors, the garage and the roofline; granules across the yard that wake back up each time you water; and a spray along the fence and property line (our services page). Webs we can reach come down on the first visit (our FAQ). The inside is treated on request and isn't drawn. Illustration: Bastion Pest Control.

First, a band at the foundation, 3 feet up the wall and 3 feet out, around window frames, doors, the garage and the roofline. Second, yard granules that wake back up each time you water. Third, a spray along the property line, where bugs get onto your lot.

That's 40+ pests on every visit, plus rodent control and bait stations on the base plan. Here's everything your visit includes. Plans start at $97 a month for a single-family home.

How long does pest control last after a visit?

There's no single number. How long a treatment hangs around depends on things like sun, heat and water, says the National Pesticide Information Center.

In one University of California study, concrete treated for ants sat out in summer weather and repeated fake rain. All but one formula had quit killing ants by day 20. That's bare concrete in a test, not your lawn.

Worried about storms? Here's what we say about rain. If a hard storm ever beats one, re-treatments are free on any active recurring plan.

What's out in each two-month stretch of the year?

Something's out in every stretch. What changes is which bugs you'll run into.

Bi-monthly pest control year wheel: six two-month stretches around a Central Texas ranch house, one visit in each A flat cartoon year wheel on a cream background, split into six wedges that run clockwise from the top: a bare tree in frost, a rain cloud over bluebonnets, a warm sun over green grass, a blazing sun over dry yellow grass, rain and wind with falling leaves, and brown leaves on the ground. A small ranch house sits in the middle, and six orange dots around the rim, joined by arrows that run clockwise, mark one visit every two months. WHAT'S OUT, TWO MONTHS AT A TIME Six visits a year, one in every two-month stretch. JAN-FEB Most photos: ants Wasp queens may wander in MAR-APR Most photos: spiders Wasp queens start nests MAY-JUN Most photos: spiders Mosquito peak starts NOV-DEC Most photos: spiders Mosquito peak runs to Nov SEP-OCT Most photos: spiders Fall fire ant flights JUL-AUG Most photos: spiders Fire ants may dig deeper bastion PEST CONTROL
What's out, two months at a time. The most-photographed group in each stretch comes from our own count of research-grade iNaturalist photos in Travis County, 2016 to 2025: photos people chose to post, not bug counts. Paper wasp queens frequently enter homes in winter, especially during warmer periods, and start new nests in spring (Texas A&M). Fire ant mating flights are most common in spring and fall (Texas A&M fire ant project), and fire ants may disappear in hot, dry weather as they move deeper (Texas A&M, 2023). Mosquitoes are present year-round, with peak activity from May through November (Austin Public Health). Mosquito treatment comes with our larger plan. The drawing shows the seasons, not insects. Illustration: Bastion Pest Control.

And how often should pest control be done in winter? On our plans, same schedule. We counted ten years of Travis County photos on iNaturalist, where people post nature photos and others agree on the ID. All six groups showed up in every stretch.

Around Austin, pest photos turn up in every two-month stretch

Our count of research-grade iNaturalist records, 2016 to 2025: each two-month stretch's share of photos of six household pest groups (orange) next to its share of all records in Travis County (gray).

Share of Travis County pest photos by two-month stretch, next to the share of all records January and February: 5.9% of the 27,755 photos of the six pest groups (1,638), 8.2% of all research-grade records in the county.

  • Six household pest groups
  • All research-grade records
Our own count of research-grade iNaturalist records of ants, cockroaches, spiders, scorpions, wasps (Vespidae) and mosquitoes in Travis County, 2016 to 2025 (27,755 photos), next to all 810,900 research-grade records of any species there in those years, counted on 2026-10-18. Every one of the six groups shows up in every two-month stretch. These are photos people chose to post, not pest counts, and more people are out looking in mild months, so read it as a pattern, not a census.

In Jan-Feb, pest photos dip a bit more than all photos do. And they're photos people chose to post, not a bug count. More detail: the month-by-month pest calendar.

Does a hard freeze reset things? KXAN asked Texas A&M bug expert Wizzie Brown in 2021.

Texas A&M AgriLife entomologist Wizzie Brown talks with KXAN meteorologist Nick Bannin about whether the February 2021 freeze would cut Central Texas insect numbers. Source: "Weather Q&A: Will insects be a problem after the winter storm?" KXAN on YouTube, published 2021. It runs 1 minute 52 seconds. She says insects are just fine in a normal Central Texas winter, hiding or digging down, that most Texas mosquitoes spend the winter as eggs, which hold up well, and that she expected no big drop in insects that spring and summer.

Bugs showed up a month after the visit. Now what?

Call us. On any active recurring plan, we come back free between visits, with no limit and no trip fee.

After a visit, you'll usually see a big drop within a few days. Roaches and ants can take up to two weeks, since the treatment has to travel back to the nest.

Last summer a homeowner met me in the driveway holding a can of hardware store ant spray like a fire extinguisher, and the garage reeked of it. I told him to retire the can and call, since the trip back is free on his recurring plan.

Skip these between visits

  • Grabbing a can of bug spray. NC State says to let a treatment work before you spray more. Some, like baits, are slow on purpose.
  • Putting up with a new wasp nest. On a plan, a new one that turns up between your visits comes down free.

Common questions

How often should you get your house sprayed for bugs?

On our plans, every two months, so six times a year. If you add mosquitoes, that treatment comes every 30 days. Most of that work happens outside: around the foundation, across the yard and along the fence line. We'll treat inside when you ask, at no extra cost.

Do I need pest control in the winter?

On our schedule, yes. Your Nov-Dec and Jan-Feb visits still happen. Our iNaturalist count found photos of all six pest groups in both winter stretches. And Texas A&M says paper wasp queens often come inside in winter, especially on warm spells. Here's why Austin has no real off month for bugs.

How long does pest control take to work?

You'll usually see a big drop within a few days. Roaches and ants can take up to two weeks, because the treatment has to travel back to the nest. Still seeing them after that? Call us. Re-treatments are free on any active recurring plan.

Does bi-monthly pest control mean every two months or twice a month?

It can mean either. The American Heritage Dictionary lists both: every two months, or twice a month. That's why we just say every two months. Our plans come out every two months and are billed monthly.
