Marin County sits just north of the Golden Gate Bridge, where coastal fog rolls in off the Pacific and keeps humidity high across most of the county. Many homes here were built in the late 1800s and early 1900s as summer retreats, leaving aging wood frames and crawl spaces that attract termites and rodents alike. The county's open space preserves and oak woodland corridors run right up to residential lots, giving roof rats and mice a direct path into attics and wall voids. From Sausalito in the south to Novato in the north, the mix of historic cottages, mid-century ranches, and hillside estates means pest pressure looks different on every property.

Pest Control Service
Every Marin property is inspected before any work begins. A hillside home in Fairfax with a raised foundation has different entry points than a flat-lot ranch in Corte Madera. We look at your specific structure, identify where rodents are getting in, and close those gaps with the right materials for that opening.
H&I was built on honesty and integrity because the owner saw firsthand how larger companies pushed unnecessary treatments on customers. In Marin, where homes range from pre-war bungalows to modern hillside builds, the right solution for a drywood termite problem in an old-growth redwood beam is not the same as the right solution for a subterranean colony under a concrete slab. We match the treatment to the actual problem.
Payment is collected only after the work is done. You get a thorough home inspection, a clear cost estimate for labor and materials, and a scheduled work date before any money changes hands. That process protects Marin homeowners from surprise charges and gives you full visibility into what is being done and why.
At a glance
Rodent exclusion and rodent trapping are the most requested services across Marin County, where roof rats use mature oak and bay tree canopies to reach rooflines. Termite treatments and wood-eating insect identification are equally in demand because so many homes carry original redwood and Douglas fir framing that drywood and subterranean termites target. Vapor barrier installation addresses the crawl space moisture that the county's fog-driven humidity creates under raised foundations. Insulation cleanout and remediation round out the work after rodents have nested in attic or crawl space insulation.

Common questions from Marin County, CA customers about our services, process, and coverage.
As dry-season food sources in Marin's open space preserves and oak woodlands run out, roof rats and mice move toward residential structures for warmth and food. Homes with raised foundations, aging crawl space vents, or gaps around roofline utilities are the first to see activity. Sealing those entry points before the first rains is the most effective way to stop an infestation before it starts.
Yes. Many Marin homes built before World War II contain original redwood and Douglas fir framing that both drywood and subterranean termites target. Drywood termites infest attic spaces and eaves without needing soil contact, while subterranean termites build mud tube networks through the moist soil common under Marin crawl spaces. A wood-eating insect identification inspection is the starting point for understanding which species is present and what treatment fits.
Marin's coastal fog keeps relative humidity elevated for much of the year, and that moisture collects under homes with dirt-floor crawl spaces. A vapor barrier blocks ground moisture from rising into the crawl space, which reduces the damp conditions that attract subterranean termites, wood-destroying fungi, and rodents seeking water. It also protects insulation from moisture damage.
Rodents nest in attic and crawl space insulation, leaving behind droppings, urine, and nesting debris that carry health risks and reduce insulation performance. After trapping and exclusion are complete, insulation cleanout and remediation remove the contaminated material so the space is safe and the insulation can do its job again.
