Rodent Management
Rodent Control in Gilroy, CA
101 Exterminators handles rodent control in Gilroy exclusion-first: find the openings, seal them, then trap what is already inside. We have worked the agricultural edge of South Santa Clara County since 2005 under SPCB Lic. #9119. Norway rats leave garlic and row-crop ground when the fields get worked, and the houses backing onto that ground take the first wave — usually within days of the tractors.
Warning Signs
Signs You Need Rodents Service in Gilroy
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 Gilroy
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Gilroy.
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 Gilroy
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 Gilroy
Why do rats show up in my Gilroy house right after the fields get worked?
Because discing and harvest destroy the burrows they were living in, and a Gilroy house is the nearest dry, warm place with food. This is displacement, not a population boom — the same rats simply relocate a few hundred feet. Properties that back onto working ground do best when the exterior stations and the exclusion work are already in place before the field turns over, not after the first rat is in the attic.
How do I tell roof rats from Norway rats in Gilroy?
Look at where the activity is. Norway rats are heavy-bodied with a blunt nose and a tail shorter than the body; they burrow at ground level, along creek banks, under sheds, and in field margins, and they come into a Gilroy house low — crawl space, garage, wall base. Roof rats are slimmer with a tail longer than the body; they climb, and they show up in attics, along fence tops, and in fruit trees. Gilroy has both, so the trapping plan changes with the species.
Is sealing my Gilroy house worth it if the field next door is still there?
Exclusion is the only part that keeps holding after we leave, so yes — especially next to permanent pressure. Bait and traps lower the population that is there today; they do nothing about the next group that walks over from the same field in August. Sealing the openings, screening the vents, and keeping the vegetation and stored wood off the walls is what turns a recurring problem into an occasional one.
