How to Get Rid of Termites (2026 Guide)

Termites punish the two classic homeowner instincts: spraying what you see and waiting to see more. Visible swarmers and tubes mark a colony months or years old, and surface sprays scatter foragers while the queen lays on. Real elimination runs underground or inside wood through slow chemistry professionals apply: non-repellent soil liquids, growth-regulator baits, fumigation gas, each matched to the termite type. Your job is identification, preparation and hiring well. Their job is everything involving gallons, drills and gas.

Key takeaway: name the termite type first, then hire a licensed pro for soil liquids, bait stations or fumigation matched to it. Homeowner work stops at moisture fixes, documentation and bid comparison. For example, a ranch with drillable slab perimeter and confirmed subterraneans wants liquid-barrier bids, while a finished basement over wells wants bait-station bids.

Which termites are eating the house?

Treatment follows species, so name it first. Subterranean termites are soil-nesting colonies that commute through mud tubes to wood, causing the vast majority of US structural damage. Drywood termites are wood-dwelling colonies that live entirely inside dry timber with no soil contact, common along coasts and the South. The split decides everything. Soil liquids and ground baits cannot touch a drywood colony. Fumigation gas is overkill sold to subterranean jobs that liquids handle. Confirm with the three-trait check in termites vs flying ants, then read the secondary signs in termite signs.

A colony massed in carton nest material. Thousands of hidden workers sit behind every visible tube.

Formosan underground termites deserve special respect where established across the Gulf Coast, Hawaii and spreading pockets: bigger colonies, faster damage, harder elimination. Treat any Formosan ID as urgent. Call this week. Ask each bidder to name Formosan jobs completed. Any vague answer ends the interview. Any Formosan ID upgrades urgency from months to weeks and favors companies with specific Formosan experience. Carton nests above ground, massive swarm clouds and aggressive foraging all mark their presence. Every method below still applies, but bid comparisons should name the species and size the program to it.

How do pro underground treatments work?

Two proven systems, often combined. Non-repellent liquids (fipronil, imidacloprid, chlorantraniliprole) soak soil around foundations, and foragers cross unknowingly, carrying doses home that cascade through the colony. NC State notes these barriers hold five-plus years in soil, with annual inspections maintaining the shield. Expect trenching, rodding and slab drilling on treatment day: disruptive, fast, and routine for licensed crews.

Bait stations trade speed for thoroughness. In-ground canisters ring the structure. Workers feed on growth-regulator bait. The colony collapses over three to six months at 90 to 100 percent efficacy in trials. A Texas field program erased whole local populations with single cartridges per colony in many cases. Baits shine where drilling proves impossible: finished basements, wells under slabs, wells and sensitive sites. Texas A&M warns the honest limits. Stations take time to discover. Cleared ground invites new colonies. DIY stakes rot out in months while costing more than they appear.

The telltale highway: a mud tube bridging mulch to siding. Break a test section and watch it rebuild.

Tennessee’s control manual frames the homeowner’s choice practically: baits disrupt nothing indoors and dodge drilling, while liquids deliver decades of barrier precedent. Combination programs, liquid wraps plus bait monitoring, now dominate quality bids. Either way the contract matters more than the chemistry: diagrammed findings, named products, warranty years, inspection schedule and retreatment terms in writing before drilling starts.

How do you spot drywood pellets?

Look down, not up. Drywood termites kick tiny hexagonal pellets from pinholes overhead, so piles collect on sills, floors and furniture below the colony. Roll grains under a magnifier: six-sided ends mark termites, while round or irregular grains mark ants, roaches or dirt. Colors follow the wood eaten, from pale pine to dark hardwood. Fresh piles grow daily; old piles sit flat and dusty. Photograph each pile with a coin for scale before sweeping any, since the inspector reads location plus volume to map colony size.

What happens on treatment day?

Know the routine before the truck arrives. For liquid jobs, the crew trenches soil along the foundation, drills through slabs and porches on a tight grid, injects measured doses, then plugs and patches each hole. Expect noise, dust and a full day on site for an average home. Pets and kids stay elsewhere until sprays dry and dust settles. For bait jobs, the visit runs quiet: techs auger slim holes around the yard, drop in stations, map each one, and leave. No drilling, no dust, under an hour in most yards. Fumigation day looks different: the crew tents the whole house, posts warning signs, releases the gas, then tests the air before handing back the keys two to three days later. You sleep elsewhere with pets, plants and food properly bagged or removed. In all three cases, walk the finished work with the crew chief before paying the balance.

The bid-comparison scorecard

Grade every quote on the same rows before signing. Demand a findings diagram. Demand the species named. Demand the method rationale. Demand product names and station counts. Demand warranty years plus void clauses. Demand the inspection fee in writing. Two complete bids compare on price. Incomplete bids hide the comparison. Never buy the cheapest undocumented promise against a documented program.

What about drywood termites?

Different biology, different arsenal. Colonies live inside furniture, framing and hardwood floors with no ground contact, so soil work wastes every dollar. Small accessible colonies answer to local treatments: injected wood preservatives, targeted heat, or borate sprays on exposed wood. Widespread or inaccessible colonies need whole-structure fumigation. Tented gas penetrates every board over one to three days. Aeration testing clears the house before reentry. Only licensed fumigators with proper equipment run either program; DIY foggers neither penetrate wood nor carry the gas.

Preparation decides fumigation success. Bag or remove food, medicine, plants, pets and mattresses per the company checklist. Arrange two to three nights elsewhere. Trim landscaping off the tent seal line. After clearance, prevention from prevent termites at home takes over. The gas leaves no residual shield. Sealed paint, dry wood and annual inspections carry the future.

Situation	Method	Expect
Underground, drillable perimeter	Non-repellent liquid barrier	Feeding stops in weeks, 5-year soil life
Underground, slabs or wells	Bait stations	Colony gone in 3 to 6 months, quarterly checks
Underground, complex construction	Liquid plus bait monitoring	Highest confidence, highest price
Drywood, localized	Wood injection, heat, borates	Same-week resolution, verify with scopes
Drywood, widespread	Whole-structure fumigation	1 to 3 days tented, no residual shield
Any, DIY ambition	Moisture fixes, monitoring, prep	Supports pros, never substitutes

What can homeowners actually do?

Everything around the chemistry. Fix plumbing and roof leaks first. Grade soil away from foundations. Keep siding six inches above grade. Separate all wood-to-ground contact including firewood, form boards and mulch volcanoes. Ventilate crawl spaces and keep vapor barriers intact. Photograph every tube, pellet pile and swarm with dates before touching anything, since documentation prices bids accurately. Clear inspection access: move storage off basement walls, unlock crawl spaces and gates, and keep pets secured on treatment days.

Money planning lives in termite treatment cost. It covers per-foot liquid pricing, per-station bait pricing, and fumigation cubic-foot math. It decodes the warranty fine print that separates real coverage from marketing. Get two bids minimum, check state licensing boards for complaints, and never pay in full before the final walkthrough confirms diagrammed work completed.

Confirm, prep or sign? Decide in 60 seconds

Match your situation to one row and commit.

• Tubes or swarmers found: photograph, jar specimens, stop disturbing. Inspectors this week.
• Underground type confirmed: collect liquid and bait bids on the scorecard. Compare, then sign.
• Drywood confirmed: scope the extent with a pro, fumigate or locally treat. No soil work.
• Post-treatment quiet: keep inspections annual, moisture fixed, monitors watched. Maintain.
• New tubes after treatment: call back under warranty immediately. Retreatment is the point of it.

The termite hub gathers the full campaign: signs, ID, costs and prevention alongside this hub. Compare the full roster across all pests. Open the pro finder the moment tubes, swarmers or hollow wood enter the picture, because termites are the one pest where DIY ends at documentation.

1. Confirm subterranean versus drywood

   Mud tubes, soil contact and swarmers point subterranean; kick-out pellets and clean galleries point drywood. Photograph everything before touching it.

2. Prep moisture and access

   Fix leaks, grade soil, clear crawl spaces and move storage off walls so the inspector reaches every footing and sill.

3. Collect two bids minimum

   Demand diagrammed findings, liquid versus bait rationale, product names, warranty years and retreatment terms in writing from each company.

4. Verify the kill

   Watch tubes stay dry and unrepaired, monitors go quiet across seasons, and annual inspections continue. New activity restarts the call, not the worry.

Frequently asked questions

Can I treat termites myself?

Only the margins. Homeowners can fix moisture, separate wood from soil, and monitor, but soil termiticides need licensed equipment, drilling and gallonage math no DIY kit matches. Consumer bait stakes decay in months and cost more than they appear. Detection is DIY; elimination is pro work with a warranty.

Which works better, liquid treatment or bait stations?

Both clear colonies when done right. Non-repellent liquids act in weeks as treated-soil barriers that foragers carry home. Baits eliminate colonies over three to six months with less pesticide and disruption. Many companies now pair both. Annual inspections guard either method afterward.

How do you treat drywood termites?

Whole-structure fumigation for widespread colonies, or local wood injections, heat and borate treatments for small accessible ones. Soil liquids and ground bait stations cannot touch colonies living entirely in dry wood. A pro maps every gallery with meters and scopes before choosing.

How long does termite treatment take to work?

Liquids stop feeding in the structure within weeks. Baits need three to six months of steady feeding to erase a colony, with activity sometimes pulsing as one colony after another falls. Retreating at the first new tube beats waiting for visible damage.

Do termite treatments come with warranties?

Pro jobs should: typically one to five years with annual inspections, covering retreatment and sometimes repair. Read what voids it, usually lapse in inspections, new moisture damage, or unapproved construction. Bait contracts cost more yearly because stations get checked up to four times annually.
