There are two main professional termite treatments: a chemical barrier (a treated zone around your home that termites can't cross undetected) and a baiting system (stations termites carry poison back to the colony from). Often the best result combines both — which suits your home depends on its construction, the soil, and where the activity is.
A liquid termiticide is applied in a continuous treated zone around and under the home. Modern non-repellent products are undetectable to termites, so they pass through, pick up the chemical and carry it back to the colony. The result is a long-lasting protective zone.
In-ground and above-ground stations hold a bait that termites feed on and share through the colony, eliminating it over several weeks. Baiting is useful where a full barrier is hard to install, and doubles as ongoing monitoring.
When there's live termites in the structure, a technician can treat them directly with foam or dust to knock the colony back, before installing the barrier or baiting for long-term protection.
It depends on construction (slab vs subfloor), soil and access, landscaping, and whether you want ongoing monitoring. A good inspector recommends based on your specific home — not whatever product they happen to sell.
A typical treatment runs around $2,500–$4,500+. Barriers protect for several years depending on the product, while baiting provides ongoing protection while it's monitored. Annual inspections keep either one honest.
Neither is universally better; it depends on your home's construction and where the termites are. Many homes get the best result from a combination of both.
A chemical barrier typically protects for several years depending on the product and soil; baiting systems protect while monitored. Annual inspections keep either effective.
Not always — but high-risk homes often benefit from a preventive barrier or baiting. An inspection tells you whether it's worth it for your property.
