Rodent Management
Rodent Control in Mountain View, CA
101 Exterminators handles rodent control in Mountain View exclusion-first: find the openings, seal them, then trap what is already inside. We are California licensed under SPCB Lic. #9119 and have worked Santa Clara County since 2005. Roof rats dominate here because Mountain View's 1950s and 1960s tracts came with deep yards, and seventy years later those yards grew a canopy that touches roofline after roofline.
Warning Signs
Signs You Need Rodents Service in Mountain View
Our program combines three components: (1) Exclusion — sealing gaps in foundations, pipe penetrations, vents, and roof eaves using hardware cloth, copper mesh, foam sealant, and sheet metal as appropriate. (2) Trapping — placement and monitoring of snap traps, live traps, and glue boards in active areas. (3) Exterior bait stations — tamper-resistant bait stations positioned along perimeter rodent runways for ongoing population management.
Droppings along walls, in cabinets, behind appliances, or in attic insulation
Gnaw marks on wiring, wood, plastic pipes, or food packaging
Grease marks along walls or baseboards — oil from rodent fur rubbed repeatedly on surfaces
Nesting materials (shredded paper, insulation, fabric) in hidden locations
Scratching or scurrying sounds in walls, ceilings, or under floors at night
Burrows in landscaping, mulch beds, or under concrete slabs
Citrus or avocado fruits with bite marks — a classic roof rat indicator
Pet acting alert at walls or cabinets when no visible cause exists
How It Works
Our Rodents Process in Mountain View
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Mountain View.
Inspection & Runway Mapping
We identify gnaw marks, runways, burrows, droppings, and grease trails to map rodent activity throughout the property — interior and exterior.
Exclusion
We seal all discovered entry points with durable materials appropriate to the opening — hardware cloth, copper mesh, sheet metal flashing, or foam sealant for smaller gaps.
Trapping & Bait Placement
Interior snap traps and exterior tamper-resistant bait stations are positioned along active runways. We monitor and service these on a schedule until activity ceases.
Follow-Up & Monitoring
We return to clear traps, replenish bait, check exclusion work, and confirm that the population has been eliminated before closing out the service.
Why 101 Exterminators
Rodents You Can Count On in Mountain View
Exclusion-First Methodology
Without sealing entry points, any rodent removed will simply be replaced by another. We seal the structure before or concurrent with trapping — not as an afterthought.
No Unmonitored Poison Bait Indoors
We do not place loose rodenticide indoors where rodents can carry it to walls and die inaccessibly. Interior work uses traps with daily monitoring during active treatment.
Regional Species Knowledge
Norway rats, roof rats, and deer mice behave differently and require different approaches. We identify the species present before selecting treatment methods.
Sanitation Recommendations
After resolving an infestation, we advise on harborage removal, vegetation management, and food storage to prevent reinfestation — not just a repeat service call.
Common Questions
Rodent Control FAQs for Mountain View
Why do Mountain View homes get roof rats instead of Norway rats?
Roof rats are the climbers, and Mountain View is built for climbing. The mature street and fruit-tree canopy over the 1950s and 1960s tracts lets them travel above ground from yard to roof, so activity shows up as attic noise and eave-line damage rather than burrows in the lawn. Norway rats do occur here, mostly along the creek channels and around commercial dumpsters, and they stay low: ground floor, sub-area, sewer lateral.
Do I have to cut down the trees around my Mountain View house to keep rats out?
You need clearance, not removal. Trimming limbs so nothing overhangs or touches the roof takes away the bridge, and picking up dropped fruit takes away the reason to cross. The orchard leftovers in Sylvan Park and Waverly Park yards are a real late-summer food source. Sealing the roofline still matters, because a rat that can reach the roof off a fence or a downspout will find the eave gap anyway.
I hear scratching in the ceiling of my house near Whisman Station: what is that?
Scratching or running overhead after dark is almost always roof rats in the attic or a ceiling joist bay. Mice make lighter, faster sounds, and squirrels are active in daylight. Around North Whisman the creek corridors and the older garden-apartment blocks both hold rat populations, so the entry is usually at the roofline rather than at ground level. The next step is an attic inspection. Droppings and runways identify the species and the scale.
