Rodent Management
Rodent Control in Palo Alto, CA
Exclusion · Trapping · Bait Stations · Sanitation
Setting traps without sealing entry points is like bailing water from a boat with the plug still out. 101 Exterminators' rodent control programs begin with thorough exclusion — identifying and sealing every gap, crack, and opening larger than a quarter-inch — combined with strategic trapping and bait placement. Serving Palo Alto and surrounding Santa Clara County.
Warning Signs
Signs You Need Rodents Service in Palo Alto
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 Palo Alto
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Palo Alto.
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 Palo Alto
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 Palo Alto
How do I know if I have roof rats vs. Norway rats?
Roof rats are agile climbers — evidence is typically in attics, rafters, upper walls, and fruit trees. Their droppings are elongated with pointed ends (about 12mm). Norway rats burrow in soil and travel along ground level — they prefer basements, crawl spaces, and the lower floors of structures. Their droppings are blunt-ended capsules (about 18-20mm). Activity location is the key indicator; we identify species during the initial inspection.
How long does rodent exclusion take?
A standard residential exclusion service takes 2–4 hours for most homes. Larger structures, slab-on-grade homes with many pipe penetrations, or properties with significant landscape features near the structure may take longer. We provide a time and cost estimate before beginning work.
Can rats chew through steel wool?
Yes — steel wool compresses and rodents chew through it within weeks. We use hardware cloth (1/4-inch galvanized mesh), sheet metal, and copper mesh depending on the application. For permanent exclusion, the right material for each specific opening is essential.
Is rodent control dangerous for my pets?
Exterior bait stations are tamper-resistant and not accessible to dogs or cats under normal use. We discuss bait placement relative to your pets' behavior and access areas. Interior treatment uses snap traps placed out of pet reach. We always review product choices with you before use.
