WHAT IS THE BEST
TERMITE TREATMENT?
There's no single "best" termite treatment that works for every home. The most effective approach depends on what species you're dealing with, whether you have an active infestation or are trying to prevent one, and how your home is built. This guide breaks down every major treatment method — how it works, what it's good for, and what it can't do — so you can understand what you actually need.
TERMITE TREATMENT METHODS COMPARED
Here's an honest breakdown of every major termite treatment method used today — including what pest control companies don't always tell you upfront.
LIQUID BARRIER
A termiticide (typically fipronil, the active ingredient in Termidor) is injected into the soil around and beneath your home's foundation, creating a continuous chemical barrier. Subterranean termites can't detect it — they pass through the treated zone, pick up the termiticide on their bodies, and carry it back to the colony. The entire colony is eliminated through this "transfer effect," often within 90 days.
Pros
- +Proven colony elimination, not just repulsion
- +Long residual — typically 5–10 years
- +Works on active infestations and as prevention
- +Effective against subterranean and Formosan species
- +Non-disruptive — no need to vacate the home
Cons
- –Doesn't help with drywood termites
- –Requires trenching around foundation
- –Soil disruption may be needed for slab homes
Active subterranean termite infestations and whole-home prevention. The standard of care for Central Texas.
BAIT STATIONS
Plastic stations (like Sentricon) are installed in the soil around your home's perimeter. Each station contains wood material that attracts foraging termites. When termites are detected, the wood is replaced with a slow-acting bait containing a chitin synthesis inhibitor — a chemical that prevents termites from molting. Termites feed on it, share it with nestmates, and the colony gradually collapses. Stations are inspected quarterly.
Pros
- +Low chemical footprint — no soil injection required
- +Continuous monitoring between services
- +Good for homes near wells or sensitive environments
- +Works well as a long-term prevention system
Cons
- –Slower — colony elimination can take 6–12 months
- –Termites have to find the station (not guaranteed)
- –Requires ongoing quarterly service to be effective
- –Higher long-term cost than a one-time liquid treatment
Prevention and long-term monitoring. Often combined with a liquid treatment for active infestations.
DIRECT / SPOT TREATMENT
Termiticide foam or liquid is injected directly into active termite galleries — through drilled holes in walls, floors, or wood members — to kill termites that are actively feeding. This is a targeted intervention, not a whole-home solution. It's typically used to stop an active infestation quickly while a broader treatment plan is put in place.
Pros
- +Fast knockdown of active feeding sites
- +Works on both subterranean and drywood species
- +Low overall chemical volume
Cons
- –Does not address the whole colony
- –Misses galleries that weren't located
- –Not a standalone solution — reinfestation is common
Drywood termites in localized areas; as a supplement to a full liquid treatment on active infestations.
FUMIGATION (TENTING)
The entire home is enclosed in a tent and filled with sulfuryl fluoride gas. The gas penetrates every void, crack, and piece of wood, killing all termites present at the time of treatment. Residents must vacate for 2–3 days. This is the gold standard for severe drywood termite infestations spread throughout the structure.
Pros
- +Kills 100% of termites present throughout the structure
- +Reaches areas no other method can
- +Single treatment — no ongoing service required
Cons
- –Requires vacating the home for 2–3 days
- –No residual — does not prevent future termites
- –Most disruptive and expensive treatment option
- –Overkill for most Central Texas infestations
Widespread drywood termite infestations throughout a structure. Rarely needed for subterranean species.
HEAT TREATMENT
Industrial heaters raise the temperature inside the home — or a specific room or wall cavity — above 120°F and hold it there long enough to kill termites through the wood. No chemicals involved. Effective for drywood termites in localized or whole-structure applications. Technicians use thermal probes to confirm lethal temperatures are reached in wood members.
Pros
- +No pesticides — good for chemically sensitive households
- +Can be done room-by-room or whole-structure
- +Kills all life stages including eggs
Cons
- –Expensive — specialized equipment and extended labor
- –No residual protection after treatment
- –Can damage heat-sensitive items if not removed
- –Not effective for subterranean termites
Drywood termite infestations where chemical use is a concern. Niche application — not a routine treatment.
WHAT WORKS BEST IN CENTRAL TEXAS
For the subterranean and Formosan termites that are most common in Central Texas, a liquid termiticide barrier — combined with ongoing bait station monitoring — is the most effective treatment protocol available. It eliminates the current colony and provides years of residual protection against future foragers.
Fumigation and heat treatment are rarely necessary here unless you have a confirmed, widespread drywood infestation. Most Central Texas homeowners do not.
WHICH TREATMENT IS RIGHT FOR YOUR HOME?
Three factors determine the right treatment: whether you already have an active infestation, what species you're dealing with, and how your home is built.
ACTIVE VS. PREVENTION
I have an active infestation
You need a full liquid barrier treatment and, in most cases, direct spot treatment of active galleries. Do not wait. Every day termites feed is more structural damage.
I want to prevent termites
A liquid barrier treatment provides long-term prevention (5–10 years). Bait stations are a lower-cost monitoring option but require ongoing quarterly service to be effective.
SUBTERRANEAN VS. DRYWOOD
Subterranean termites (mud tubes present)
Liquid barrier treatment with fipronil is the most effective proven option. These termites must travel through soil to reach your home, making a soil-applied termiticide highly effective.
Drywood termites (frass present, no mud tubes)
Spot/direct treatment for localized infestations. Fumigation if the infestation is widespread throughout the structure. A liquid barrier will not help — drywood termites don't touch soil.
SLAB VS. PIER-AND-BEAM
Slab foundation
A liquid barrier is applied by trenching around the perimeter and drilling through the slab at entry points. More labor-intensive but highly effective. Most Central Texas newer construction is slab.
Pier-and-beam foundation
Access to the crawlspace makes treatment easier and allows direct inspection of floor joists and piers. Liquid barriers are applied to the soil beneath. Older Central Texas homes and rural properties are often pier-and-beam.
WHY DIY TERMITE TREATMENT DOESN'T WORK
Hardware store termite products are designed to be sold, not to solve the problem. Here's why they consistently fail.
REPELLENTS PUSH TERMITES AROUND
Most consumer termite products use repellent chemistry — termites avoid the treated zone and find another entry point. A colony of 500,000 termites is not stopped by a repellent. They route around it and keep eating.
WRONG CONCENTRATION
Professional termiticides like Termidor are applied at precise concentrations in the soil. Consumer products are formulated differently — weaker actives, no soil penetration, no transfer effect. They're not the same product.
APPLICATION REQUIRES EQUIPMENT
A proper liquid barrier treatment requires a professional-grade rod injector, hundreds of gallons of diluted termiticide, and knowledge of where to apply it around your specific foundation type. A can of spray does none of this.
YOU CAN'T SEE WHERE THEY ARE
Termites live in the soil and inside your walls. Without a thermal imaging camera, moisture meter, and trained eye to identify gallery patterns and species, you're treating blind — and missing the colony entirely.
COLONY NOT ELIMINATED
Spot-killing visible termites doesn't matter. A subterranean colony lives 10–20 feet underground and has hundreds of thousands of workers. Killing surface foragers has zero impact on the colony's survival.
DAMAGE CONTINUES DURING DELAY
Every week spent on ineffective DIY treatment is another week of feeding. Termite damage repair averages $3,000–$10,000 and is almost never covered by homeowners insurance. The delay costs more than professional treatment.
OUR RECOMMENDATION FOR CENTRAL TEXAS HOMES
After years of treating termites across Bastrop, Lee, Travis, and Williamson counties, here's what we recommend — and why.
For the vast majority of Central Texas homes — whether slab or pier-and-beam — a fipronil-based liquid barrier treatment is the most effective and durable option available. The transfer effect eliminates the entire colony, not just foragers, and residual protection lasts 5–10 years.
Even after treatment, we recommend quarterly inspections to verify the barrier integrity, check for new termite pressure, and catch any activity early. Central Texas has high year-round termite pressure — monitoring is not optional, it's protection.
For homes with significant property perimeter or high-value landscaping, we'll often add bait stations as a secondary interception layer. They catch colonies before they reach the treated zone and give us early warning of new pressure.
