Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Liquid Soil Termiticide Barrier
$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.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Localized Wood, Foam, and Borate Treatment
$250–$1,500
For new decks, additions, or repairs in San Bernardino, borate on the framing is cheap insurance. Ask to have the wood treated before it's closed in.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Fumigation for Drywood Termites
$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.
- Time
- 2–3 days including tenting and aeration
- Best for
- Widespread drywood termites throughout a structure
Prices are typical published ranges. Ask what’s included before you compare quotes.

Local termites conditions in San Bernardino.
A provider who works San Bernardino and California every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Knowing San Bernardino's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. An inspection in San Bernardino usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around San Bernardino, the area is mostly urban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. San Bernardino sits in a semi-arid climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Which termites live around San Bernardino.
They'll eat fences, door frames, anything wooden. In San Bernardino's dry heat, desert subterranean termites can build tubes that hang free from ceilings. Look for tiny piles of pellets that look like coarse sand. Drywood termites are common around San Bernardino as well, flying straight into attic framing, eaves and furniture without any soil contact. It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in San Bernardino is the desert subterranean termite.
When termites swarm here.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Drywood termites around San Bernardino tend to swarm in late summer and fall. Around San Bernardino, desert subterranean termites usually swarm from July through September, around dusk after monsoon storms. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from San Bernardino out to Fontana and Moreno Valley. Keep soil and mulch below the slab edge. Outside, watch for mud tubes behind shrubs. Look where pipes come through the floor. Check the garage edges and behind baseboards. Many homes in San Bernardino sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in San Bernardino.
- Winter: a good time to book an inspection in San Bernardino, before swarm season starts. - Fall: with about 16 inches of rain a year in San Bernardino, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 96°F in San Bernardino, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Summer: swarm season in San Bernardino, usually after monsoon storms. Watch porch lights at dusk.
Ways to keep the cost down.
- Book before swarm season, when schedules fill up. - If you already have a warranty, keep the renewal current. - Ask about both bait and liquid options for your house. - Fix leaks and drainage first. Moisture brings termites back. - Get two or three quotes, and compare what each one covers.
What happens at an inspection.
Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. On a slab, they focus on joints, cracks and pipe gaps. Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the San Bernardino crew applies the product, and ask how long to stay off treated soil. In California, Reticulitermes swarm in the afternoon in spring or fall on clear days after a soaking rain; drywood swarmers fly in daytime during summer and fall; Heterotermes aureus flies late afternoon/early evening in July–September (UC IPM). Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations.
Mulch and termites.
Wood chips touching the siding trap the moisture termites are after. A dry gap along the house makes mud tubes easier to spot; in San Bernardino's dry climate the risk is irrigation and leaky hose bibs rather than rain. Pull mulch back from the foundation and keep the layer thin.
Questions to ask before you sign.
- What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot? - What product or system will you use? - Which termites did you find, and where?
What affects the price
- Amount of drilling through concrete and patios.
- Cubic footage under the tent for fumigation.
- Species: subterranean, drywood, or Formosan.
- Whole-house fumigation versus spot treatment.
- Wells, drains, or water features limiting chemical use.
- Slab, crawl space, or basement construction.
- Warranty type: retreatment only or damage repair.
- Number of bait stations required.

What's your biggest concern about termite control costs?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way.
What you can do yourself
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see.
