Rodent Management
Rodent Control in Pacific Grove, CA
101 Exterminators does exclusion-first rodent control in Pacific Grove: we find and seal the entry points before we set a single trap. Roof rats (Rattus rattus) are endemic here, moving through the mature Monterey cypress and pine that shade nearly every street between Lighthouse Avenue and the shoreline. We are a California-licensed exterminator, SPCB Lic. #9119, working Monterey County since 2005.
Warning Signs
Signs You Need Rodents Service in Pacific Grove
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 Pacific Grove
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Pacific Grove.
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 Pacific Grove
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 Pacific Grove
Do I have to cut down the cypress trees around my Pacific Grove house to stop roof rats?
No. Tree removal is not part of effective roof rat control and we do not recommend it in Pacific Grove, where the canopy is part of what the city is. The work that matters happens on the building — sealing eave gaps, vent screens, and roofline junctions so the rats have nowhere to enter after they land. Trimming branches back a few feet from the roofline helps, but that is pruning, not removal.
What is scratching in my Pacific Grove attic ceiling right at dusk?
That pattern points to roof rats running an established route, and dusk is when they start moving. Roof rats are nocturnal and travel the same path each night, which is why the sound repeats in the same direction at the same hour. Mice make a lighter, faster scratching, and squirrels are active in daylight, so timing is a useful clue. An attic inspection settles it — droppings, rub marks, and flattened runways in the insulation are unmistakable.
How do rats get into a Pacific Grove home that has a sealed foundation?
Roof rats usually enter above the foundation, not through it. On Pacific Grove homes we most often find the opening at an eave, at a gable vent whose screen has corroded in the salt air, around a wall plumbing or electrical penetration, or where a later addition meets the original roofline and left a gap under the flashing. A sealed foundation is worth having, but it addresses Norway rats and house mice more than the species that dominates this city.
