Rodent Management
Rodent Control in Oakland, CA
101 Exterminators does rodent control in Oakland by sealing the building first and trapping second, California licensed under SPCB Lic. #9119 and a California-licensed business. Roof rats (Rattus rattus) travel Oakland's mature fruit-tree canopy and the wires above flatland streets. Norway rats (Rattus norvegicus) work the ground line near the culverted creeks and the estuary. Bait alone fixes neither one.
Home maintenance
How do you keep rats out of an Oakland house?
Seal openings at the roofline and at the foundation, because Oakland has both rat species. The Alameda County Vector Control Services District says roof rats have a wider range in the county than Norway rats, and Norway rats live in Oakland's sewers. District research found more rodent calls in rainy years, so close gaps before the November storms.
Screen vents with heavy galvanized mesh
UC IPM specifies 18-gauge, 1/2-inch galvanized expanded metal over ventilator grills and warns against chicken wire. Check attic, gable and foundation vents on Oakland bungalows, where a century of paint and settling can leave screens loose or torn.
Cap rooftop plumbing vents
UC IPM recommends screening rooftop plumbing vent pipes more than 2 inches across, since roof rats climb. Look at the roof from the street or the hillside above your house in winter, when deciduous trees are bare and the vents are easier to see.
Seal door thresholds and garage corners
UC IPM says exterior doors should fit tight and seal at the threshold, and double doors need the gap between leaves sealed. A detached 1920s or 1930s garage with a warped wood door can leave gaps at the corners. Add a sweep and close corner gaps over 1/4 inch.
Keep compost in a rigid bin
UC IPM advises keeping compost in rigid plastic or metal containers with tight lids. An open pile in the back corner of an Oakland flatland yard can feed rats through the winter. Switch to a closed bin set on hardware cloth so rats can't dig in from below.
Ask the county district for advice
Biologists with the Alameda County Vector Control Services District identify rodents, find entry points and recommend rodent-proofing. If you can't find how rats get in, call the district and compare its list with what you have sealed.
When to do it
Finish exclusion work in October, ahead of the winter rains the district links to more rodent calls.

Warning Signs
When to Ask About Rodent Control in Oakland
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
What to Expect from Rodent Control in Oakland
Tell us where you hear activity or find droppings, and whether you can see a possible entry point. We can then plan where to check first.
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
Why Choose 101 Exterminators for Rodent Control in Oakland
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 Oakland
I hear scratching in the attic of my Oakland bungalow at night. Roof rats or squirrels?
Night activity in the attic is almost always roof rats, since squirrels are daytime animals. Rattus rattus climbs and enters high, at a roof vent, a fascia gap or a branch touching the eave, so the noise runs along the ceiling after dark and quiets by morning. Look for a greasy rub mark at the entry and dark, pointed droppings about half an inch long. We find the opening, seal it, then trap what stayed inside.
Do the storm drains and creek culverts under East Oakland bring rats onto my block?
Yes. The culverted stretches of Sausal, Peralta and Lion Creek and the storm drain system they feed are standing Norway rat habitat, and rats surface wherever that system opens: cleanouts, catch basins, broken sewer laterals, crawl-space vents. That is a neighborhood-scale source no trapping program removes. What your property controls is exclusion at the ground line, plus keeping fallen fruit, pet food and green-bin waste off the ground.
Does rodent exclusion work when the neighbor's wall is only a few feet from mine?
It does, because exclusion is about your building envelope rather than the block. The shared exposure on a narrow Oakland lot is real, since it is the same fence line, the same fruit trees and the same drain, so we seal every opening on your structure larger than about a quarter inch and place exterior stations on the runways crossing the property. Neighbors who do the work at the same time get a better outcome, and we hand you the entry photos to pass along.
