Getting a termite treatment scheduled is the right call, but most homeowners have never been through one and do not know what is actually going to happen. The treatment sounds significant, with technicians working around the foundation and trenching into the soil, and people want to know how disruptive it is, how long it takes, whether they need to leave, and what happens afterward. The short version: it is less disruptive than most people expect, and a same-day return to normal is the standard.
Quick answer
Most termite treatments for a standard Houston home take three to five hours. The technician trenches and treats along the foundation, treats accessible interior void areas, and installs monitoring or bait stations if applicable. You stay out of treated areas for a short drying period, then return to the home normally. There is no tenting required for subterranean termites.

The Inspection Comes First
Before any treatment starts, a licensed technician does a thorough inspection of the structure. This covers the exterior foundation, any accessible crawl space or subarea, the garage, interior areas along the base of walls, and any visible wood-to-soil contact points. The goal is to identify where termite activity is concentrated, what species are involved, and what the extent of damage looks like.
The inspection dictates the treatment plan. A home with active termites in one isolated area is treated differently than one with widespread mud tube activity around the full perimeter. The inspection also identifies conditions that should be corrected to reduce future risk: wood debris under the house, soil grade issues, plumbing leaks near the foundation.
Liquid Barrier Treatment: How It Works
For subterranean termites, a liquid barrier treatment is one of the most common approaches. The technician trenches a shallow channel around the exterior perimeter of the foundation and applies a termiticide solution into the soil at depth. This creates a treated zone that termites cannot cross without contacting the product.
Interior treatments address areas where the foundation meets the soil inside: garage slab edges, bath traps, interior expansion joints, and any structural voids that provide termite access. For slab construction, some of the treatment may require drilling through the slab at specific points to inject product below. Holes are plugged and patched after treatment.
Modern termiticides include non-repellent products that termites cannot detect. They pass through the treated zone and carry the product back to the colony, extending the treatment's reach into nesting areas below the soil.
Sentricon Bait Stations: The Other Main Option
Sentricon is a baiting system installed in the soil around the home. Plastic stations go in at intervals around the perimeter, and foraging termites find them, feed on the bait, and share it with the colony. The active ingredient disrupts the molting process, eventually collapsing the colony including the queen.
Installation takes a few hours and does not require trenching or drilling into the slab. Stations are monitored on a recurring schedule so activity can be tracked and bait refreshed as needed. Sentricon is a good fit for homes where minimal soil disruption is a priority or where the colony location makes a liquid barrier less practical.
Day-Of Expectations and What Comes Next
A standard liquid barrier treatment for a typical Houston home, slab-on-grade construction in the 1,500 to 2,500 square foot range, takes three to five hours from start to finish. You do not need to vacate the home for the full treatment, but you may be asked to stay out of specific areas (like the garage or a crawl space) while the technician is working in them.
After the exterior treatment, there is a brief period while the soil and product settle before foot traffic resumes around the foundation. Indoor treated areas need to dry before re-entry. By the end of the treatment day, normal household activity can resume.
Activity from existing termites does not stop immediately after treatment. Subterranean termites already inside the structure may continue to be seen for days or even a few weeks while the product works its way through the colony. This is normal. If you see activity several weeks after treatment, contact the technician. That is what the warranty is for.
