What Affects Termite Treatment Cost? Key Factors Explained (2026)
Six factors determine what you will pay for termite treatment. Home size and treatment type have the biggest impact, but region and severity can swing the price by 50% or more.
Home Size
The single biggest price driver. Treatment is priced per linear foot (perimeter) or per square foot. A 3,000 sq ft home costs roughly double a 1,500 sq ft home for the same treatment type.
Treatment Type
Spot treatment ($200-$800) vs fumigation ($2,000-$8,000). The right treatment depends on termite species and infestation extent, not budget alone.
Region
Labor rates, termite pressure, and competition all vary by region. Southeast and West Coast run 15-20% above national average. Midwest is 10% below.
Infestation Severity
A mild, localized problem caught early may cost $500. A severe infestation with structural damage can push the total past $10,000 when you add repair costs.
Termite Species
Subterranean termites are the cheapest to treat. Drywood termites often require fumigation, the most expensive option. Formosan termites cause the most damage.
Foundation Type
Slab foundations require drilling through concrete for liquid treatment. Crawlspaces allow easier access but may need vapor barriers. Basements add treatment area.
Cost by Home Size
Estimated perimeter calculated as 4 x sqrt(sq ft). Actual perimeter depends on home shape.
| Home Size | ~Perimeter | Liquid Barrier | Bait Stations |
|---|---|---|---|
| 1,000 sq ft | 126 ft | $380-$2,500 | $1,200-$2,500 |
| 1,500 sq ft | 155 ft | $465-$3,100 | $1,500-$3,000 |
| 2,000 sq ft | 179 ft | $535-$3,580 | $1,800-$3,500 |
| 2,500 sq ft | 200 ft | $600-$4,000 | $2,000-$4,000 |
| 3,000 sq ft | 219 ft | $660-$4,380 | $2,200-$4,400 |
| 4,000+ sq ft | 253+ ft | $760-$5,060+ | $2,500-$5,000+ |
Cost by Region
Regional averages for a standard 2,000 sq ft home with moderate infestation. Costs include the most common treatment (liquid barrier for subterranean, fumigation for drywood).
| Region | Cost Range |
|---|---|
| Southeast (FL, GA, AL, SC, NC, LA, MS) | $600-$3,200 |
| Southwest (TX, AZ, NM) | $550-$2,800 |
| West Coast (CA, OR, WA) | $650-$3,500 |
| Midwest (OH, IL, IN, MO) | $400-$2,200 |
| Northeast (NY, NJ, PA, CT) | $500-$2,500 |
| Pacific (HI) | $700-$3,800 |
State-Level Cost Highlights
Florida
$600-$3,500+
Highest termite pressure in the continental US. Subterranean, drywood, and Formosan all present. Fumigation common in South Florida.
Texas
$290-$1,500
Lower labor costs bring prices down. Subterranean termites dominate. Formosan termites increasing in Houston and Gulf Coast areas.
California
$800-$3,500
Drywood termites in Southern California often require fumigation. Higher labor costs statewide. Bay Area and SoCal are most expensive.
Georgia
$500-$2,500
High subterranean termite pressure. Competitive market with many providers keeps prices moderate.
North Carolina
$450-$2,200
Subterranean termites throughout the state. Moderate pricing with good provider competition.
Louisiana
$500-$2,800
Formosan termites are a major concern, especially in New Orleans. These require more aggressive treatment.
South Carolina
$450-$2,400
High humidity and subterranean pressure. Coastal areas see higher termite activity.
Alabama
$400-$2,200
High termite risk statewide. Lower labor costs keep treatment affordable.
Hawaii
$700-$3,800
Formosan and drywood termites year-round. Island pricing and limited competition push costs higher.
Cost by Infestation Severity
| Severity | Treatment Cost | Potential Repair Cost |
|---|---|---|
| Minor | $200-$800 | $0-$500 |
| Moderate | $500-$3,000 | $1,000-$5,000 |
| Severe | $1,500-$8,000 | $5,000-$35,000+ |
Early detection reduces total cost dramatically. Annual inspections ($75-$300) are the best investment against severe damage.
Cost by Foundation Type
Slab Foundation
May require drilling through concrete to inject termiticide beneath the slab. Adds $100-$300 to treatment cost. Limited access for inspection.
+$100-$300 premium
Crawlspace
Easier access for treatment and inspection. May need a vapor barrier ($500-$2,000) to control moisture that attracts termites.
Standard pricing
Basement
Additional treatment area below grade. Interior perimeter treatment may be needed alongside exterior. Good inspection access.
+$200-$500 premium
