⚠️ Termite Damage Is Not Covered by Homeowner's Insurance
Standard homeowner's insurance does not cover termite damage. A single subterranean termite colony can cause $15,000–$50,000 in structural damage before detection. Annual professional inspection is the most cost-effective protection available.
Professional vs. DIY
When DIY Is Appropriate
- Preventive treatment on an uninfested home
- Spot treatments for drywood termites in isolated wood
- Monitoring with bait stations in low-risk areas
- Small, clearly localized infestations confirmed by an inspector
When Professional Treatment Is Required
- Any subterranean termite infestation (most common type)
- Active structural damage confirmed by inspection
- Drywood termite whole-structure fumigation
- Most mortgage/real estate transactions require professional certification
Top Treatment Products
#1 Professional — Gold Standard
Termidor HE (Fipronil 9.1%)
★★★★☆ 4.9/5 (– reviews)
$400–$1,200 (professional)
Fipronil liquid termiticide applied around the foundation as a continuous treated zone. The Transfer Effect — termites pass the active ingredient to nestmates — collapses the entire colony. Provides 10+ years of protection. Most widely used termiticide in the US.
- Transfer Effect eliminates entire colony
- 10+ year residual
- Non-repellent — termites don't avoid it
- Industry gold standard
- Requires licensed applicator
- Expensive — $400–$1,200+ depending on structure
- Not available to consumers
Best Eco-Friendly Pro Treatment
Altriset (Chlorantraniliprole)
★★★★☆ 4.8/5 (– reviews)
$500–$1,500 (professional)
The newest major termiticide, approved 2010. Lower mammalian toxicity than any previous termiticide. Rapid termite paralysis while maintaining the Transfer Effect. Excellent for homes with young children, pets, or chemical sensitivities.
- Extremely low mammalian toxicity
- Transfer Effect — eliminates entire colony
- Safe around wells and water features
- More expensive than Termidor
- Professional application required
Best DIY Liquid
Taurus SC (Fipronil 9.1%)
★★★★☆ 4.8/5 (6,201 reviews)
$60–$80 (20 oz)
Same active ingredient as Termidor at the same concentration, labeled for consumer use. Requires trenching around the perimeter and filling with diluted product. Highly effective when applied correctly. Saves $300–$900 vs professional application.
- Same active ingredient as Termidor
- Significant cost savings
- Transfer Effect — kills entire colony
- 10+ year residual
- Requires proper application and trenching
- Easy to apply incorrectly
- No warranty or guarantee
Best Bait System
Sentricon (Pro) / Spectracide Terminate (DIY)
★★★★☆ 4.6/5 (12,847 reviews)
$20–$40 (DIY) or $800–$2,000/yr (pro)
Bait stations around the foundation deliver IGR bait that sterilizes and eventually collapses the colony. Slower than liquid treatment but no trenching required. Professional Sentricon is far superior to consumer Spectracide Terminate.
- No trenching required
- Excellent monitoring system
- No chemical in soil
- Slower than liquid (6–12 months to eliminate)
- Professional systems require annual service fee
