How it works
Termite treatment runs $800–3,500 for most homes. Liquid barriers ($8–12/linear ft) trench around the foundation and last 5–10 years. Bait stations ($1,000–2,500 + $300/yr monitoring) are less invasive and great for prevention. Fumigation ($1,500–4,000+) is the nuclear option for drywood termites — whole house tented.
The inspection matters more than the treatment: a proper inspection takes 45–90 minutes, includes crawlspace and attic, and produces a diagram of findings. A 10-minute walkaround ending in a scary quote is a sales pitch.
Treatment and repair are separate bills. Killing termites costs thousands; fixing what they ate can cost tens of thousands. The cheapest termite job is the one you never need — fix moisture and wood-to-soil contact first.
Frequently asked questions
How much does termite treatment cost?
Liquid barrier: $800–2,000. Bait systems: $1,000–2,500 plus ~$300/year monitoring. Fumigation: $1,500–4,000+. Heavy infestations with damage run higher.
Liquid vs bait — which is better?
Liquid is faster (kills on contact, immediate barrier) and cheaper long-term. Bait is less chemical, better for prevention and sensitive sites, but needs ongoing monitoring visits.
How do I know if I have termites?
Mud tubes on foundations, hollow-sounding wood, discarded wings near windows, frass (pellet droppings). Subterranean termites are invisible until damage is done — hence inspections.
Is fumigation necessary?
Only for drywood termites (common in warm coastal states) or severe widespread infestation. Subterranean termites — the most common — are handled with liquid/bait without tenting.
How long does treatment last?
Liquid barriers: 5–10 years. Bait stations: indefinite with monitoring. Fumigation: one-time kill, no residual protection — pair with prevention after.
Should I get a warranty?
Yes — a retreatment warranty means they come back free if termites return. Read the fine print: most require annual inspections ($150–300) to stay valid.
Can I DIY termite treatment?
Spot treatments with consumer products exist, but colonies are rarely where you see them. DIY misses the queen; pros find the colony. This is a hire-a-pro job.
What causes termite problems?
Moisture + wood-to-soil contact. Fix: grade soil away from foundation, keep 6"+ clearance between soil and siding, fix leaks, store firewood away from the house.
Do I need treatment when buying a home?
A termite inspection ($75–150) is standard in purchase contracts in termite-prone states — and often required by VA/FHA lenders. Active infestation can renegotiate the price.
Are the chemicals safe?
Modern termiticides (fipronil, imidacloprid) are applied in soil trenches and wall voids, not living spaces, and are EPA-registered. Bait stations use tiny amounts. Discuss concerns with the operator.
