When you find termite damage, the first question is always: how much will this cost? In my 100+ termite jobs, acting fast almost always costs less than months of hidden damage.
Termites feed on wood around the clock and cause more harm each year than fires or floods. According to the National Pest Management Association, termite damage tops $5 billion per year nationwide. Knowing what treatment costs helps you plan and act quickly.
What Drives the Cost
Several factors affect what you’ll pay. Every home and infestation is different.
- How bad the infestation is (localized vs widespread)
- Type of termite (subterranean vs drywood)
- Home size and layout (crawl space vs slab)
- Soil conditions and moisture near the structure
- How easy it is to access the foundation for trenching or drilling
Inspection Costs
A professional termite inspection runs $75-$200, depending on home size. Some companies charge by the linear foot of foundation. Many providers include a free inspection when you request service.
What they check: mud tubes on foundation walls, hollow wood when tapping trim, winged swarmers near lights, and live termites in soil or probe holes.

Treatment Options and Costs
Liquid Barrier Treatments
Liquid treatments involve trenching and drilling around the foundation to apply termiticide. Non-repellent liquids let termites contact the barrier, then carry poison back to the colony.
Cost: $3-$16 per linear foot of foundation. For an average home with 200 ft of perimeter, expect $1,000-$3,200 for the initial treatment. Annual renewals run $100-$300.
Best for: Subterranean termites. Quick protection. Works well for severe infestations where you need fast results.
Bait Systems (Sentricon)
Bait stations are placed every 10-20 ft around your home. Termites feed on the bait, carry slow-acting poison back to the colony, and cause it to collapse over months.
Cost: $8-$12 per linear foot, or $1,500-$3,000 for initial setup. Annual maintenance runs $300-$500. Many programs include a termite bond that covers damage repair if termites break through while you’re under contract.
Best for: Prevention and early-stage problems. Long-term colony elimination. Lower stress than liquid treatments.
Fumigation (Tenting)
Whole-structure fumigation kills drywood termites inside all wood. You’ll need to leave the home for 2-3 days. Tenting does NOT prevent subterranean termite reinfestation. You’ll still need a barrier or bait system after.
Cost: $1-$4 per square foot. A 1,200 sq ft home may cost $1,200-$2,500. A 2,500 sq ft home can run $2,200-$3,800. Complex rooflines push costs higher.
Best for: Widespread drywood termite problems inside walls that you can’t reach with other methods.
Here’s how costs break down by how serious the infestation is.
Cost by Severity
| Severity | Treatment Type | Cost Range |
|---|---|---|
| Localized (spot treatment) | Targeted application | $200-$600 |
| Moderate infestation | Liquid barrier or bait | $1,000-$3,000 |
| Severe/full structure | Liquid + bait or tenting | $2,500-$5,000+ |
Treatment Cost vs Damage Cost
The numbers make a clear case for treating early rather than waiting.
The national average for termite treatment is about $1,500. The average repair bill for termite damage is $1,800, often rising to $5,000-$10,000 if left unchecked. One homeowner we worked with faced over $15,000 in repairs versus a $1,500 preventive plan.
Research confirms termite prevention costs less than repairs.
One more factor that makes early action critical:
Termite Species and Treatment
The type of termite you have affects both treatment method and cost.
According to the University of Georgia, subterranean termites are found in every state except Alaska. This makes them the most common termite threat for American homeowners.
In our region, subterranean termites are the main concern. They nest underground and need soil moisture. Treatment uses liquid barriers or bait systems.
Drywood termites live inside wood above ground. They’re less common here but may need fumigation. Formosan termites are rare in our area but very aggressive if introduced.
DIY vs Professional
Professional technicians use calibrated injection tools, EPA-registered termiticides, and proper application methods that consumer products can’t match. For more on treatment methods, see how to kill termites and how to get rid of termites.
Preventive Plans and Warranties
Many termite programs include:
- Annual inspection by registered technicians
- Unlimited callbacks for retreatment if termites return
- No long-term contracts (cancel anytime with notice)
- Coverage for treatment materials and labor
Termite bonds cover damage repair if termites break through while you’re under contract. This gives you financial protection on top of the treatment itself.
Choosing a Termite Company
Check local experts like Northern Virginia Termite Control or Alexandria Termite Control.
Conditions That Raise Cost
Some home conditions increase both termite risk and treatment cost:
- Earth-to-wood contact on decks or siding
- Mulch piled against the foundation
- Stumps or firewood stored near the house
- Poor drainage or HVAC units trapping moisture
- Packed crawl spaces that block access
Fixing these issues lowers termite activity and can reduce treatment needs.
Our Recommendation
In my experience, proactive bait systems like Sentricon often cost less and cause less stress when caught early. Severe subterranean termite problems sometimes need targeted liquid treatment with products like Premise or Termidor for a faster fix.
