Structural Pest Inspections

Pest Inspections in Los Altos, CA

101 Exterminators performs pest inspections in Los Altos and issues state-compliant Wood Destroying Organisms reports for escrow, refinance and pre-listing, under California SPCB Lic. #9119 since 2005. A WDO report separates Section 1 — active infestation or existing damage — from Section 2 — conditions likely to lead to infestation. In housing stock this age, most Los Altos houses generate findings in both columns.

Local Context

In a City That Rebuilds, a Los Altos WDO Report Answers a Different Question

The standard path is familiar to anyone who has closed a Santa Clara County transaction. The inspector reports what is there, escrow turns on the Section 1 items, and once those are corrected the clearance document — the Notice of Work Completed — goes to the file. In Los Altos that process runs against framing that is mostly six decades old or more, so pre-listing reports here routinely surface earth-to-wood contact at planter beds, fungus damage at a shower wall, and drywood evidence in the eaves.

The wrinkle is the rebuild market. Modern two-story custom houses now stand between original 1950s ranches on the same block, and a share of Los Altos buyers are purchasing with a deep remodel or a replacement in mind. For that reader the report is not a repair-credit negotiation — it is scope information about which framing survives into the new house and what the sub-area soil conditions are before anyone pours. We write the report to the same state standard either way; what changes is what the reader does with it.

Access decides report quality more than anything else in this city. On a raised-floor ranch the sub-area is the report — if the hatch is buried behind storage or the clearance is too tight to traverse, the document has to state what could not be reached, and an inspection full of unreached areas is weak in escrow. Eichlers and slab houses have no sub-area at all, so the report leans on exposed beam ends, the roof-deck edge, the slab perimeter and the garage framing instead.

How We Work in Los Altos

We inspect to California SPCB standards: attic, sub-area, all accessible exterior wood, garage, decking and fencing within the report scope. We look for drywood and subterranean termites, wood-decay fungi, carpenter ants, and conducive conditions such as wood-to-soil contact, planter beds against stucco, and grade set too high on the foundation. On Los Altos ranch homes we ask ahead of time that the crawl-space hatch be cleared and the side gates left open, because unreached areas on the report are the thing that slows a closing.

Los Altos Climate

Los Altos has a warm Silicon Valley climate with summer temperatures reaching 84–92°F and mild winters with 15–17 inches of rainfall. Its central valley position gives it consistent temperatures without the hillside extremes of Los Gatos or Saratoga. The mature tree canopy throughout the city creates a slightly cooler, more humid microenvironment at the street level that maintains Argentine ant activity and soil moisture year-round.

Housing Stock

Los Altos is defined by its 1950s–1960s ranch homes on well-maintained lots throughout virtually the entire city. These homes — now 60–70 years old — represent the heart of the drywood termite risk in Los Altos: original wood framing, original window trim and exterior siding, and crawl spaces that have been aging for decades. Custom and newer construction exists in smaller quantities near the hills adjacent to Los Altos Hills.

Why Local Expertise Matters

Los Altos' uniformly established 1950s–1960s housing stock means the entire city faces a similar generation of termite vulnerability simultaneously — we see this reflected in the consistent inspection findings throughout the city. Our 20 years of service in Los Altos gives us a thorough understanding of where drywood termite activity concentrates in this specific housing era.

Common Questions

Pest Inspections FAQs for Los Altos

What is the difference between Section 1 and Section 2 on a Los Altos WDO report?

Section 1 is active infestation or existing damage — live drywood termites, fungus-damaged framing, an eaten sill. Section 2 is a condition likely to lead to infestation, such as earth-to-wood contact at a planter, a leaking hose bib, or cellulose debris in the sub-area. Lenders and escrow generally turn on Section 1, and clearing those items is what produces the Notice of Work Completed. Section 2 findings are not usually required for the transaction, but on a house from the 1960s they are the reason the Section 1 items appeared.

We are buying a Los Altos house to remodel or rebuild. Is a WDO report still worth ordering?

Yes, for different reasons than a standard buyer has. The report tells you which framing is compromised before a designer starts planning around it, documents sub-area moisture and drainage conditions that affect a foundation decision, and gives your lender the disclosure it needs regardless of your plans. It also establishes the condition of anything you intend to keep — an original beam ceiling, a garage that stays, a detached structure. Finding fungus damage at the framing stage is much cheaper than finding it after demolition has been scoped.

What should I clear before a pest inspection on a Los Altos ranch house?

Clear a path to the crawl-space hatch and the attic access, open the side gates, and move stored items away from garage walls and interior perimeter walls. The inspector has to physically reach the sub-area and the attic, and boxes stacked over a hatch become an unreached area on the report. It also helps to pull furniture off exterior walls in any room with a known moisture history, and to leave the water heater closet and under-sink cabinets accessible.

Drywood Termites

1950s–1960s ranch homes throughout Los Altos have original wood framing that is now 60–70 years old — prime territory for established drywood termite colonies

Subterranean Termites

Older crawl spaces with limited vapor barriers and creek-adjacent soil moisture see consistent subterranean termite foraging activity

Argentine Ants

Supercolonies extend throughout the fully-developed residential grid, supported by the consistently irrigated landscaping that maintains soil moisture year-round

Roof Rats

Dense mature urban tree canopy throughout Los Altos provides widespread arboreal rat habitat with direct roofline access to older homes via overhanging branches

Black Widows

Mature landscaping, wood storage, and garage interiors throughout Los Altos's established neighborhoods are common black widow locations
