How to Get Rid of Termites (2026): Treatment Options That Actually Work

To get rid of termites, first identify the type: subterranean termites are treated with a soil-applied liquid barrier or in-ground bait stations, while drywood termites are treated with whole-structure fumigation or localized spot and heat treatments. Because termites damage the structure itself, this is a job for a licensed pro who backs the work with a warranty, not a DIY spray.

Termites are different from almost every other household pest, and it changes how you deal with them. A cockroach or a mouse is a nuisance and a health concern, but a termite colony quietly eats the wood that holds your house up. The damage happens inside walls, floors, and framing where you never see it, and by the time you notice, a mature colony may have been feeding for years. That is why termite control is treated as a specialty across the industry: the stakes are structural, the treatments require specialized equipment and licensed products, and reputable work comes with a renewable warranty. This guide walks through the termite types, the real treatment methods and how they compare, what DIY can and cannot honestly do, and how to keep termites from coming back.

The single most important decision is matching the treatment to the termite type, because a method that eliminates one type does almost nothing to the other. So start there.

First, identify which type of termite you have

In the United States, the two types that matter for homeowners are subterranean termites and drywood termites. Subterranean termites are by far the most common and the most destructive nationwide. They live in the soil, build mud tubes to reach wood above ground, and need contact with moisture, so they attack from the ground up. Drywood termites live entirely inside the wood they eat, need no soil contact, and are concentrated in warmer coastal and southern regions. They often infest attics, furniture, and framing well above ground.

Two quick field tests help you tell them apart. Look along the foundation and in the crawlspace for mud tubes, thin, pencil-width tunnels of dried soil running up the concrete, which are a subterranean signature. Then look for frass: drywood termites push their droppings out of the wood, leaving small mounds of what looks like sawdust or tiny ridged pellets below the infested area. If you see swarming winged insects indoors in spring, save a few in a bag for the inspector, they help confirm the species. For a fuller checklist of what to look for, our overview of termite control covers the warning signs in detail.

The signs, briefly

Before treatment, confirm you actually have an active infestation. The most reliable signs are mud tubes on the foundation or in the crawlspace, discarded wings near windowsills and doors after a spring swarm, wood that sounds hollow when tapped, floors or paint that bubble or blister, and frass pellets under drywood-infested wood. Doors and windows that suddenly stick can also signal that termites have weakened the frame. Any one of these warrants a professional inspection, guessing at the species and extent from the surface almost always undercounts the problem.

• Mud tubes: pencil-width soil tunnels on foundations, piers, or crawlspace walls (subterranean).
• Frass: small piles of pellet-like droppings below infested wood (drywood).
• Discarded wings near windows and doors after a swarm.
• Hollow-sounding or blistered wood, and paint that bubbles.
• Doors or windows that stick as frames warp from damage.

Termite treatment methods, compared honestly

There are four main professional approaches, and each is built for a specific situation. No single method is best for every home. The right choice depends on the termite type, how the structure is built, how widespread the infestation is, and your local climate. Here is what each one does and where it fits.

Liquid soil barrier (termiticide)

For subterranean termites, a liquid termiticide applied to the soil around and under the foundation is the long-standing standard. A licensed technician trenches around the foundation and injects the product to create a continuous treated zone. Non-repellent modern products are undetectable to termites, so they pass through the treated soil, pick up the active ingredient, and transfer it through the colony. Done properly, a liquid barrier can protect for roughly five to ten years, but it requires precise, complete application, gaps in the barrier are exactly where termites get through, which is a core reason this is not a DIY job.

Bait stations

Bait systems are the other main approach for subterranean termites. In-ground stations are installed in the soil around the home at intervals; termites find the bait, feed on a slow-acting growth inhibitor, and carry it back to share with the colony, which can eliminate the colony over weeks to months. Baiting is less disruptive than trenching, works well where soil conditions or construction make a continuous liquid barrier hard to achieve, and doubles as an ongoing monitoring system. The trade-off is that it works more slowly than a liquid barrier and depends on regular professional monitoring and refills, usually under a service plan.

Fumigation (tent fumigation)

Fumigation is the go-to for widespread drywood infestations, especially when termites are established throughout a structure and cannot be reached spot by spot. The building is sealed under a tent and a fumigant gas is introduced that penetrates all the wood and eliminates termites throughout the structure. It is highly effective at reaching hidden drywood colonies, but it requires the household to vacate for two to three days, offers no residual protection against future infestations once the gas clears, and demands preparation like bagging food and arranging pets. It is a specialized, licensed operation, never a DIY option.

Spot treatment and heat treatment

When a drywood infestation is localized and confirmed to a specific area, spot treatments target just that wood, by drilling and injecting termiticide or foam into the galleries, or by applying localized heat that raises the wood to a lethal temperature. These are less invasive and less costly than tenting the whole house, and heat treatment uses no chemicals. The catch is certainty: they only work if every infested pocket has been found. Drywood colonies can be scattered, so spot treatment risks leaving hidden pockets alive, which is why an inspector, not a homeowner, should decide whether the infestation is truly localized.

Costs above are typical, approximate national ranges and vary with home size, construction, infestation severity, and region. For a fuller breakdown of what drives the number and how quotes are structured, see our termite treatment cost guide.

Why termites are a job for a licensed pro

With most pests, DIY is a reasonable first move and the downside of getting it wrong is limited. Termites are the exception, and it comes down to three things: the stakes, the tools, and the warranty.

• The stakes are structural. Termites damage load-bearing framing. An incomplete treatment does not just waste money, it lets damage keep progressing silently in wood you cannot see.
• The methods need licensed products and equipment. Effective liquid barriers, bait matrices, fumigants, and heat rigs are professional tools applied under state pesticide licensing, not consumer store products.
• Reputable treatment comes with a warranty. Professional termite work is typically backed by a renewable warranty or bond, if termites return during the term, the company re-treats at no charge. That guarantee is the real product, and DIY has no equivalent.

There is also the diagnosis itself. Correctly identifying the species, mapping how far the infestation has spread, and choosing between a barrier, bait, fumigation, or spot treatment takes an inspector who does this daily. A wrong call, for example spot-treating a drywood infestation that is actually widespread, leaves colonies alive and the homeowner falsely reassured. This is why the industry treats termites as a specialty and why we point homeowners toward license-verified termite control companies rather than a spray bottle.

What DIY can and cannot do

Being honest about DIY matters here, because the wrong expectation costs people their house's framing. DIY has a real but narrow role with termites: prevention and early detection, not colony elimination.

What DIY can do

• Reduce moisture and wood-to-soil contact, the conditions termites need (see prevention below).
• Inspect regularly, checking the foundation, crawlspace, and attic for mud tubes and frass so you catch a problem early.
• Remove obvious attractants like scrap wood, mulch piled against the foundation, and cardboard in the crawlspace.
• Treat a single infested piece of removable furniture with a targeted drywood product, a narrow, genuinely DIY-scale case.

What DIY cannot reliably do

• Eliminate a subterranean colony. Store-bought sprays kill the termites you see, not the colony in the soil that keeps sending more.
• Create a continuous liquid barrier. This needs professional trenching, injection, and complete coverage; gaps are where termites get in.
• Reach drywood termites inside walls and framing. You cannot fumigate or heat-treat a structure yourself.
• Provide any warranty. If DIY fails, the damage is silently ongoing and it is on you, with a pro, re-treatment is covered.

The most expensive termite mistake is a cheap one: spraying a visible mud tube, watching the termites disappear, and assuming the problem is solved. The colony is untouched and keeps feeding out of sight. If you have confirmed active termites, get a professional inspection before you spend money on anything.

How to prevent termites

Prevention is where a homeowner has the most leverage, and it is entirely DIY. Termites need moisture and access to wood, so the whole strategy is denying them both. None of this replaces treatment for an active infestation, but it lowers your risk and protects the investment after a pro has treated.

• Fix leaks and direct water away. Repair leaky faucets, gutters, and downspouts, and grade soil so water drains away from the foundation. Subterranean termites follow moisture.
• Break wood-to-soil contact. Keep firewood, lumber, and mulch away from the foundation, and make sure siding and framing do not touch the soil.
• Ventilate crawlspaces and attics. Reduce humidity that termites and the fungi they favor depend on; a vapor barrier in the crawlspace helps.
• Keep a clear inspection gap. Maintain a few inches of visible foundation between soil or mulch and the siding so mud tubes have nowhere to hide.
• Store wood off the ground. Keep firewood elevated and well away from the house, never stacked against the wall.
• Schedule annual inspections. A yearly professional termite inspection catches new activity before it becomes structural, and often maintains an existing warranty.

What termite treatment costs to expect

Termite pricing depends heavily on the method, the size and construction of your home, and how far the infestation has spread, so treat these as typical ranges rather than quotes. As a rough guide, a standard termite treatment commonly runs about $575 to $1,400, while whole-structure fumigation for drywood termites typically runs about $1,200 to $2,500. Localized spot treatments are lower, often a few hundred dollars, and bait-station systems add an ongoing monitoring fee on top of installation. Many homeowners also carry an annual termite bond or warranty, a recurring fee that keeps the guarantee and yearly inspections active.

Because the range is wide and the right method varies by home, the only reliable number is a quote from an inspector who has seen your property. Our termite treatment cost guide explains what pushes a quote up or down and how to compare bids fairly, and if termites are part of a broader problem, our general pest control hub covers bundled options.
