Quick answer: Bring pest control into an Austin renovation early. Book an inspection before demolition, treat exposed framing and soil while the structure is open, and put any termite soil barrier in the ground before the slab is poured. Coordinating those steps with your contractor keeps termites, rodents, and wildlife from exploiting the work.
Most Austin homeowners treat pest control the way they treat the roof: something you deal with when there's a visible problem. A renovation changes that math. Subterranean termites alone cause about $500 million in damage across Texas each year [1], and a remodel is the moment a house is most exposed to them. When a crew opens a wall, pulls up flooring, or breaks ground for an addition, the barriers that have quietly kept termites, rodents, and wildlife out of your house come apart. The work that improves your home also makes it far easier to get into, at least for a few weeks.
That's the part the remodeling blogs skip, so this guide covers when to bring pest control into a renovation, which stages carry which risks, and how to sequence treatment with your contractor so you don't pay twice to fix the same framing. It's written for Austin, where subterranean termites stay active for most of the year and the slab-on-grade construction common across Central Texas creates its own set of entry points.
Why a renovation changes your pest risk
A finished house is a sealed system, with foundations, flashing, sealed penetrations, and any existing soil treatment all working to keep pests where they belong, which is outside. Renovation takes that system apart on purpose.
Demolition kicks off several problems at once: it exposes wood framing and dark voids that were previously closed off, and termites reach the wood they need through direct contact. Open walls, disconnected plumbing, and stalled drainage add moisture, and subterranean termites depend on moisture to survive; they dehydrate quickly and stay close to soil or a leak for water [1]. New openings appear everywhere, from a doorway cut for an addition to the gap around a relocated gas line. For a stretch of weeks, your house has more ways in than it has had since the day it was built.
Debris makes it worse: torn-out lumber, stacked cabinets, and a dumpster of construction waste a few feet from your foundation make a food source and a hiding place at the same time. The EPA specifically warns against storing wood debris against the house because it draws termites toward the structure [3].
The renovation pest timeline
The most useful way to think about this is as a sequence, not a one-time treatment. Each phase of a renovation opens a different vulnerability, and the fix for each is cheapest while that phase is still open. Miss the window and you're often drilling through new concrete or reopening a finished wall to do the same job.
Before demolition starts
Getting an inspection before the first wall comes down does two things a mid-project one can't. It documents any existing termite or moisture damage while that damage is still accessible, which matters if you need to fold repairs into the renovation scope, and it maps where your current protection sits, so the crew knows what not to cut through. If you have an active termite bait system or a treated soil zone around the foundation, that information needs to reach your contractor before anyone starts trenching.
While the structure is open
This is the window that does not come again: with walls open and framing exposed, a technician can treat wood directly. Borate wood treatments work best when they're sprayed onto bare structural wood during construction, before it's covered, because getting complete coverage on wood already sealed inside a finished wall is difficult and only partial [2]. If your renovation exposes framing, that's the moment to treat it. The same logic applies to sealing: gaps around new plumbing and electrical penetrations are visible and reachable now, and they're the exact routes both insects and rodents use later.
An open renovation is also the moment to fix the conditions that draw termites in the first place. The EPA's advice is unglamorous and effective: keep the soil around the foundation dry through proper grading and drainage, including working gutters and downspouts, and leave a ventilation space between the soil and any wood [3]. If your project relocates plumbing or changes the grade around the house, those decisions determine whether the finished home stays dry or hands termites a standing water source for the next decade.
Before you close walls or pour concrete
This is the hard deadline, and it's the one people miss. For any part of the project that involves a new slab, a foundation extension, or a poured footing, the soil has to be treated before the concrete goes down. A pre-construction soil treatment puts a continuous termiticide barrier in the ground under and around the slab, and it has to be applied before the pour because no one can reach that soil afterward without drilling [4]. Once the concrete is in, the same protection means boring holes through the slab at intervals and injecting under pressure, which costs more and is never quite as thorough as treating open ground. Walls are the smaller version of the same rule: seal, treat, and inspect before the drywall goes up, not after.
After the work is done
When the project wraps, close the loop: confirm that any soil barrier disturbed by trenching or new plumbing was repaired, walk the exterior for gaps the crew left around new penetrations, and clear leftover lumber and debris away from the foundation. A post-renovation inspection catches the thing that slipped through while ten trades were moving in and out of the house at once.
Termites: the highest-stakes item in an Austin reno
A mature native subterranean termite colony can hold up to 250,000 workers, and reaching that size can take three to five years, which means an infestation that starts during your renovation may not announce itself until long after the crew has gone [1]. Austin sits in the middle of this insect's range, so the odds are not in your favor if you leave an opening.
Termites and renovations collide because of timing: they need wood in contact with soil and a steady source of moisture, and a renovation supplies both [1]. They also enter at points far from where they're eventually found, so damage discovered in a back bedroom might trace to an entry near the foundation on the opposite side of the house [2].
Pre-construction treatment goes into open soil before concrete is poured, and it's the standard to aim for because the barrier is complete and undisturbed [4]. Post-construction treatment is everything you do after the slab exists, which means drilling, injecting, and working around finished surfaces. A soil-applied termiticide barrier lasts roughly five years, with the range running from about four to ten depending on the product and the soil [1][2]. If your renovation touches the foundation in any way, the pre-construction window is worth building your schedule around. On a pre-slab visit that work is fast: a technician treats the exposed soil in the footprint and around the foundation elements so the barrier is continuous before the vapor barrier and rebar go in [4].
New construction in termite-prone areas is required by the International Residential Code to include an approved method of termite protection, which is why builders treat soil or install barriers as a matter of course [5]. A major renovation isn't held to the identical standard, but the reasoning carries over, and treating an addition to that level is cheap insurance.
Protecting the termite barrier you already have
If your home was treated when it was built or at any point since, you have a barrier in the soil around the foundation, and a renovation can breach it without anyone noticing. Trenching for a new footing, digging to run plumbing to an addition, or backfilling against the foundation all disturb treated soil and open a gap in the chemical zone. Termites find gaps; that's their entire way of life.
Slabs make this harder in a way that's specific to how Texas homes are built. Concrete slabs crack and shrink away from foundation walls over time, and they carry built-in openings at bath traps, plumbing outlets, and construction joints, all of which are routes termites use to reach the wood above [4]. A renovation that adds new penetrations adds new versions of exactly these gaps. Any spot where the existing barrier was cut needs re-treatment to restore the continuous zone, and that repair belongs in your project plan as a named step rather than an assumption that it happened.
Rodents and wildlife during the open-structure window
Termites are the long game, but rodents move faster. An open structure is an open invitation, and in Austin the timing often lines up badly, because autumn renovation season overlaps with the point in fall when cooling temperatures push rats and mice to look for indoor shelter.
The numbers explain why exclusion belongs to the framing stage rather than the punch list. A house mouse can pass through any opening larger than a quarter inch, and a rat through anything larger than half an inch [6]. Central Texas homes deal mostly with roof rats, which climb and enter high through rooflines and attics, along with Norway rats and house mice. A renovation hands all of them temporary doorways: a hole cut for a new duct, or a soffit left open overnight.
Seal while you can still reach the gaps, because openings can be packed with steel wool or copper mesh for a fast fix, then backed with quarter-inch hardware cloth and a patching compound or mortar for anything that needs to last [6]. The framing and rough-in stage is when every one of these gaps is visible; once the finishes go on, you're guessing where the hole was. Larger wildlife, from raccoons to squirrels drawn to an open attic, follows the same principle, and exclusion is far easier before the roofline and soffits are buttoned back up.
Ants and the opportunists
Not every renovation pest is a structural threat, but the nuisances are the ones you'll actually see. Disturbed soil, exposed framing, and fresh moisture bring ants, especially where a leak or a slab penetration gives them a damp path indoors. They're rarely a reason to stop work, and they usually settle once the moisture source is closed and the house is sealed. The reason to mention them is that they're an early signal. A sudden ant trail along a freshly opened wall often points to the same moisture termites are looking for, so it's worth telling your pest control provider rather than just wiping it down.
How to coordinate with your contractor
Most renovation pest problems are really coordination problems, because the general contractor is running a schedule built around framing, mechanical, and inspection dates, and pest control only lands in the right place if someone puts it on that schedule. That someone is usually you.
A few habits make the hand-off work, and the first is timing: tell your contractor at the planning stage that pest treatment is part of the scope, so the soil-treatment step lands before the pour instead of after. Share what protection already exists, including any bait stations or treated zones, so the crew avoids cutting through them or flags it when they do. Ask to be told before the slab is poured and before walls are closed, because those are your treatment deadlines. When trenching or new plumbing disturbs treated soil, get the re-treatment scheduled rather than assuming it was handled. It comes down to one conversation early and a couple of checkpoints along the way, without you having to manage the trades.
When to bring in professional support
Plenty of renovation prep is genuinely DIY: clearing debris away from the foundation, keeping gutters and drainage working so foundation soil stays dry, and sealing small gaps with steel wool and hardware cloth are all things a homeowner can do well [3][6].
The line worth drawing runs around anything that has to be complete to work. A soil termiticide barrier only protects you if it's continuous and applied correctly before the pour, which is licensed, specialized work rather than a hardware-store project [4]. Borate treatment of exposed framing, diagnosis of existing termite or moisture damage, and any drilling into a finished slab sit on the same side of that line. A Natran team member on-site during renovations will usually time the visit to the framing and pre-slab stages for exactly this reason: it's when treatment is most effective and least expensive, and it's the window that closes the day the concrete cures.
If you're planning a renovation in Austin this autumn, the plan fits in one sentence. Get an inspection before demolition, treat while the structure is open, and confirm the barrier is whole before anything gets closed up. Do that, and pest control stays a small, well-placed line in the budget instead of a repair bill after the fact.
Frequently asked questions
When should I schedule pest control during a home renovation?
Bring it in at three points: book an inspection before demolition, treat exposed framing and soil while the structure is open, and complete any soil barrier before the slab is poured or the walls are closed. Those open stages are when treatment is most effective and least expensive. Once the concrete cures, the same work means drilling.
Do I need termite treatment before pouring a new slab in Austin?
Yes, and the timing is strict: the soil under and around a slab has to be treated before the concrete is poured, because you can't reach that ground afterward without drilling through the finished slab [4]. Pre-construction treatment creates a continuous, undisturbed termiticide barrier, which is the standard to aim for in termite-heavy Central Texas.
Can a renovation damage my existing termite barrier?
Yes, easily: trenching, new plumbing runs, and backfilling all disturb treated soil and open gaps in the chemical zone around your foundation [4]. Termites exploit those gaps. Any spot where the barrier was cut should be re-treated to restore protection, so make barrier repair a named step in your project plan rather than an assumption.
Which renovation pest tasks can I handle myself?
Clearing wood debris away from the foundation, keeping gutters and drainage working, and sealing small gaps with steel wool and quarter-inch hardware cloth are all reasonable DIY jobs [3][6]. Soil barrier treatment, borate treatment of framing, and any drilling into a slab are licensed, specialized work and belong with a professional.
