How Much Does Termite Treatment Cost in 2026?

Most US homeowners pay $500 to $3,000. Liquid barrier (Termidor) for an average home runs $1,200 to $2,500. Bait stations (Sentricon) are $1,500 to $3,500 install plus $300 to $500 a year monitoring. Tent fumigation is $1,500 to $5,000 plus for drywood termites. Spot treatment for small confirmed infestations is $300 to $800.

No. Standard HO-3 and HO-5 policies exclude termite damage as a maintenance issue. The only exception is when termites cause a covered peril, for example if they chew through wiring and start a fire. Termite bonds and home warranties are the realistic financial protection.

A typical 2,000 sq ft home with subterranean termites costs $700 to $2,200 for a liquid barrier, $1,800 to $3,500 for a bait station system, or $2,500 to $6,000 for tent fumigation if drywood termites are present. Add 10 to 20 percent in high-pressure regions like Florida and the Gulf Coast.

A termite bond is an annual contract that covers re-treatment if termites return, typically $150 to $500 a year. Premium bonds also cover repair up to a cap. In high-pressure states the math usually favors a bond. In low-risk regions a bond may cost more than expected risk.

DIY products like Spectracide Terminate or Advance Bait System cost $100 to $300 but have a 20 to 40 percent success rate against active infestations. Professional treatment runs $500 to $3,000 with 90 percent plus success. Once you factor in failure probability and accumulating damage, professional treatment is usually cheaper. DIY makes sense for prevention only.

Liquid barriers (Termidor) last 5 to 10 years. Bait station systems work as long as monitoring continues. Fumigation kills all termites present but provides zero residual protection. Heat treatment same as fumigation: one-time. Most companies offer renewable warranties tied to annual inspection.

Tent fumigation costs $1 to $4 per square foot, putting a 2,000 sq ft home at $2,000 to $8,000. Vikane (sulfuryl fluoride) is the standard gas. The home must be vacated for 2 to 3 days. Fumigation is only used for drywood termites; subterranean infestations need liquid barrier or bait.

The most reliable signs are mud tubes on foundation walls (subterranean), frass pellets that look like sand grains (drywood), discarded wings near windows after a swarm, and hollow-sounding wood when tapped with a screwdriver. Blistered paint, sagging floors, and tight-fitting doors are later-stage indicators.
