The Problem

Most San Bernardino homeowners find termites by accident, during a remodel, a home sale, or a spring swarm. By that point the colony is mature. Termite damage to a San Bernardino home is rarely covered by insurance, so the cost lands on the owner. Termite queens of some species live for decades and can lay thousands of eggs per day at their peak.

Warning Signs

  • •Crumbling baseboards behind furniture
  • •Layered, honeycombed wood packed with soil
  • •Small kick-out holes in exposed wood
  • •Blistered or bubbling paint on wood surfaces
  • •Doors and windows that suddenly stick
  • •Mud tubes running up foundation walls or piers

Risks of Waiting

  • ⚠Failed home inspections and stalled sales
  • ⚠Damage almost never covered by homeowner insurance
  • ⚠Weakened deck posts and porch framing
  • ⚠Reinfestation after treatment if renewal lapses

Treatment Options

Termite Inspection and WDI Report

Typical published range: $75–$250

Inspectors in San Bernardino, California walk the crawl space, garage, and foundation line with a flashlight and probe. Moisture readings and tapped wood tell them where to look harder.

60–120 minutesBest: Every job, real estate closings, and yearly peace of mind

Liquid Soil Termiticide Barrier

Typical published range: $1,200–$3,500 (often $3–$16 per linear foot)

A soil barrier stops termites from reaching wood through the ground. For most San Bernardino homes with active subterranean termites, this is the fastest way to end feeding.

Half a day to a full dayBest: Active subterranean termites; fast knockdown around the foundation

Localized Wood, Foam, and Borate Treatment

Typical published range: $250–$1,500

For new decks, additions, or repairs in San Bernardino, borate on the framing is cheap insurance. Ask the provider to treat wood before it is closed in.

1–3 hoursBest: Small drywood spots, wall voids, and exposed framing

Fumigation for Drywood termites

Typical published range: $1,200–$4,000 (often $1–$4 per square foot)

Tenting is thorough but leaves no residual protection behind. New drywood swarmers can land on a San Bernardino home the following season, so follow-up inspections still matter.

2–3 days including tenting and aerationBest: Widespread drywood termites throughout a structure
Metal mesh and sealant around an exterior pipe penetration
Flashlight inspection of a door threshold and foundation joint

Spotting termites Trouble Early: A San Bernardino Guide

Experienced San Bernardino exterminators see the same pattern repeatedly: a homeowner notices one or two termites, tries a store-bought spray, and by the time professional help arrives weeks later, the colony has multiplied tenfold. The smartest San Bernardino residents call at the first sign—before the problem compounds. That single sighting in San Bernardino might represent hundreds you cannot see.

Evidence check: termite encounters, DIY attempts and professional help in San Bernardino

The figures in this section were compiled for San Bernardino, California readers from named public sources, each keeping its date and population, and they describe patterns across many households rather than measuring any one San Bernardino property. Thirty-five percent of U.S. homeowners in National Pest Management Association (NPMA) and Harris Poll research released March 24, 2026, said they had taken preventive measures against termites, a self-reported action rather than a verified record of treatments or inspections. If you are buying or selling a house, a termite letter is easy to source: 85% of locations in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 professionals, 2024 operations) offered real-estate inspections, a share of companies, not an infestation rate. The same question comes up in San Bernardino: Forty-one percent of U.S. homeowners ages 25–75 in HomeTeam Pest Defense's March 2022 online survey said they had not obtained a termite inspection, a self-reported figure from a survey sponsored by a pest-control company with an undisclosed sample size. A number that shapes expectations in San Bernardino as much as anywhere: an average callback rate of 1.8% was reported by termite professionals in Pest Control Technology (PCT) magazine's 2025 termite market report, a BASF-sponsored Readex survey of about 145 professionals covering 2024 operations; it is a self-reported industry average, not a guarantee for any individual treatment. Worth knowing before you call anyone in San Bernardino: if you have been ignoring scratching in the walls, you are not alone: 17% of the 2,000 U.S. respondents in ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents reported taking no action against pests, though the self-reported, pest-and-mold survey offers context, not an infestation rate. If one number should shape your next step in San Bernardino, it is how often do-it-yourself attempts fall short, which is not an argument against trying but a reason for San Bernardino homeowners to set a deadline and call a professional if the problem persists past it.

When to Call a Professional

When a neighbor in San Bernardino gets a termite treatment, it is a good time to schedule your own inspection. Subterranean colonies forage across property lines. A quick look by a San Bernardino provider costs little and answers the question. Most termite inspections take about an hour and cover the exterior foundation, crawl space, garage, and attic.

DIY vs Professional

DIY makes sense in San Bernardino for one thing: borate on bare, accessible wood in a crawl space or new addition. It is cheap and reasonably safe. For anything involving soil, slabs, or drywood galleries, a San Bernardino professional is the practical choice. Homeowner bait stakes sold at retail are mostly monitoring devices and seldom carry enough bait to eliminate a colony.

Local Context

The semi-arid climate around San Bernardino matters more to termite activity than most people expect, because temperature and moisture decide when San Bernardino properties see the most pressure. Activity typically peaks during spring swarm season (March-May), warmer earlier in the South. A provider working in San Bernardino should be able to connect these local conditions to what they actually found at your home.

Prevention Tips

  • ✓Extend downspouts so water drains away from walls
  • ✓Keep the termite renewal contract current after treatment
  • ✓Remove tree stumps and buried wood near the house
  • ✓Fix leaking hose bibs, faucets, and pipes promptly
  • ✓Use borate-treated or pressure-treated lumber for repairs
  • ✓Inspect used furniture for drywood pellets before bringing indoors

Frequently Asked Questions

How do I choose a termite company?
A strong termite proposal in San Bernardino explains itself. It names the species, the method, the active ingredient, the linear footage for your San Bernardino home, and what happens if termites return. If a San Bernardino provider cannot answer those questions clearly, keep looking.
Do I need a termite inspection when buying a house?
In most cases, yes. Many lenders serving San Bernardino require a WDI report before closing, and VA loans require one in many states. Even when it is optional, an inspection on a San Bernardino home costs little and can surface damage or old treatments the seller may not know about.
Can termites damage a house on a concrete slab?
Yes. Slab homes in San Bernardino are common termite targets because termites enter through shrinkage cracks, expansion joints, and the gaps around plumbing pipes. Once through the slab they reach wall framing behind the drywall. Treating a San Bernardino slab home involves drilling and injecting termiticide beneath it.
What is the difference between subterranean and drywood termites?
The species matters because the treatment differs. Around San Bernardino, subterranean termites are handled with soil barriers or bait stations. Drywood termites in a San Bernardino attic or window frame need localized wood treatment or, when widespread, fumigation. An inspector identifies which one you have.
Can I treat termites myself?
Partly. Fixing moisture, moving mulch, and sealing cracks are good San Bernardino, California homeowner tasks. Treating the colony is not. Retail sprays kill what they touch and warn the rest. Save the money for a San Bernardino inspection and a proper treatment.
Are termite baits or liquid treatments more common?
Most professionals use both. Before comparing San Bernardino quotes, note this: A homeowner comparing quotes should expect to see both baits and a liquid barrier proposed: 48% of professionals in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents, 2024 operations) primarily used the two together, a practice figure, not an infestation statistic. If you are in San Bernardino, use this as a starting point for questions rather than a prediction for your home.
Can you treat for termites before building a house?
Yes, and most termite companies offer it. For San Bernardino, California the relevant figure is this: Anyone planning a build can usually find a termite pre-treatment locally: 79% of locations responding to Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 professionals, 2024 operations) offered it, a percentage of companies, not a measure of how many houses get termites. Providers serving San Bernardino should be able to explain how their recommendation fits what they actually found on your property.
