Know the signs
How Do I Know If I Have Rats or Mice in My SLO Home?
Rodents are nocturnal and secretive, so most SLO homeowners notice the evidence before they ever see the animal. Scratching in the attic at night, droppings in the pantry, gnawed wiring, and hollowed-out oranges on the tree are the classic local giveaways.
Droppings tell the species
Mouse droppings are about 1/4-inch and rod-shaped; roof rat droppings are around 1/2-inch and spindle-shaped; Norway rat droppings run about 3/4-inch and capsule-shaped. Fresh droppings near food or along walls mean active traffic.
Night noises & marks
Scratching, digging, or scampering after dark points to roof rats in the attic or wall voids. Look for 1/6-inch tooth marks (rats) versus fine 1/12-inch scratchy marks (mice), plus dark rub marks where rodents travel along beams and pipes.
The citrus test
SLO's signature clue: oranges with a small hole and the pulp eaten out, leaving a hollowed rind hanging on the tree — or lemons with the rind eaten off entirely. UC Master Gardeners of SLO County call this textbook roof rat damage.

What Kind of Rodents Live in San Luis Obispo?
Three species do nearly all the damage in SLO homes. Around here, folks tend to say "field rats" — but the animal raiding the citrus and nesting in the attic is almost always the roof rat, a climbing specialist built for Central Coast living.
Roof rats
Rattus rattus — the coastal California urban rat. Smaller and sleeker than Norway rats, with a tail longer than its head and body combined. Nests aboveground in attics, wall voids, ivy, palm canopies, and dense shrubs against the house.
House mice
Mus musculus — about half an ounce, light brownish-gray with relatively large ears. They slip through 1/4-inch openings and leave a musky odor. UC IPM calls exclusion the most successful and permanent form of house mouse control.
Norway rats
Rattus norvegicus — larger, stockier burrowers that nest along foundations, under woodpiles and trash, and in gardens or fields. Indoors they stick to basements and ground floors rather than attics.
What we do
Rodent Control Services in San Luis Obispo, CA
One focused service for every rodent problem — from the first scratching sound in the attic to the final sealed entry point. Every job starts with a thorough inspection, because the species and the entry points decide the strategy.
Mice Control
Targeted trapping and exclusion for house mice — the right trap size, placed within 10 feet of activity, along walls where mice actually travel.
Learn moreRat Control
Roof rat and Norway rat removal built around how each species behaves — elevated trapping for climbers, burrow work for ground dwellers.
Learn moreRodent Exclusion
Permanent proofing: every gap over 1/4 inch sealed with the right materials — galvanized mesh, steel wool, door sweeps, vent screens.
Learn moreResidential Rodent Control
Whole-home protection for SLO homeowners — attics, crawl spaces, garages, and kitchens secured against re-infestation.
Learn moreProfessional Extermination
When DIY isn't enough: pro-grade trapping and California-legal treatment for established or hard-to-reach infestations.
Learn moreRodent Control Program
Ongoing prevention: scheduled inspections, monitoring, and maintained exclusion so rodents don't come back next season.
Learn moreAttic Cleanup
Safe droppings removal, disinfection, and insulation restoration after an infestation — never sweep or vacuum droppings yourself.
Learn moreDead Rodent Removal
Odor location and sanitary removal from wall voids, attics, and crawl spaces — plus the exclusion work that prevents a repeat.

Why We Don't Rely on Rat Poison in California
California law sharply restricts the old anticoagulant rodenticides — AB 1788 banned most second-generation poisons for structural use in 2021, and AB 2552 put chlorophacinone and warfarin behind restricted-material status in 2025. The days of baiting alone are over, and honestly, that's better pest control: UC IPM calls exclusion the most successful and longest-lasting rat strategy there is.
So we work IPM-first — inspection, sanitation, harborage reduction, exclusion, then trapping and monitoring. It's the approach that protects SLO's owls, hawks, and pets from secondary poisoning, and it's the only approach that keeps rodents from simply coming back.
What the rules say
SLO local
Rodent Control for SLO's Neighborhoods
San Luis Obispo isn't one housing type — it's 1880s Victorians downtown, student rentals by Cal Poly, 1970s tracts around Laguna Lake, and hillside homes against the Irish Hills. Each one gives rodents a different way in, so the inspection — and the fix — is different on every street.
Downtown & historic districts
Tree-lined streets of century-old homes with settlement-cracked foundations, original unsealed vents, raised crawl spaces, and aged fascia gaps at the roofline — a roof rat's dream layout. The median SLO home was built in 1979, and downtown runs far older.
Cal Poly & student rentals
With around 22,000 students and constant turnover in group houses, sanitation slips — garbage left out, cluttered garages, open pet doors. Landlord-tenant cleanup disputes are SLO's signature rodent story, and absentee owners make recurring service the smart play.
Laguna Lake & suburban tracts
Slab foundations, attached garages, and tile roofs. The weak points here are garage-door gaps, attic vents, and the gaps in tile rooflines that roof rats travel like highways.
Hillside & edge homes
Brush against the Irish Hills and the Nine Sisters foothills means deer-mouse and rat pressure straight off the hillside. Overhanging limbs and ivy slopes become elevated roof-rat routes to the roofline — trimming them back is step one.
Timing matters: roof rats stay active year-round in California, but expect the indoor surge from October through January, when the first rains and cooling nights drive them inside. Late summer and fall is when citrus damage and attic activity are most visible.

How it works
Our Rodent Control Process
No guesswork, no spray-and-pray. A proper rodent job follows the same order every time — and skipping steps is why infestations come back.
-
Inspect
Full interior and exterior inspection: species ID, entry points, nesting sites, and what's attracting them — because the species decides the trap size and the strategy.
-
Remove
Targeted snap trapping placed where rodents actually travel — along walls, off the ground for roof rats — plus secured, tamper-resistant stations outdoors where appropriate.
-
Exclude
Every opening over 1/4 inch sealed with materials rats can't chew through: galvanized mesh, steel wool, sheet metal, door sweeps, and vent screens. This is the step that ends re-infestation.
-
Monitor
Follow-up checks and an ongoing program option — because sanitation has to be ongoing, and a sealed home stays sealed only if someone keeps an eye on it.

Good to know
Rodent Control Questions, Answered
Straight answers for SLO homeowners — the same questions we hear on every inspection.
Roof rats are the coastal California urban rat — agile climbers that nest in attics, wall voids, and trees. House mice are common everywhere, and Norway rats show up around foundations and ground floors. Deer mice occur mainly on the city's rural edges.
Yes. Rodent droppings, urine, and saliva contaminate food and surfaces, and UC IPM links rats to leptospirosis, foodborne illness, and rat-bite fever. Deer mice are the primary US carriers of hantavirus — though San Luis Obispo County has zero recorded human cases, so the risk here stays precautionary, not alarmist.
Usually, yes. Locals say "field rats," but the animal raiding citrus trees and nesting in attics around San Luis Obispo is the roof rat (Rattus rattus) — a climbing species that favors attics, wall voids, ivy, and palm canopies. Knowing the species matters because it changes where traps go.
We serve all of San Luis Obispo, including Downtown SLO, the Cal Poly and University District, Laguna Lake, the Railroad District, Anholm, and the Foothill and South Higuera corridors — across ZIP codes 93401, 93403, and 93405 through 93410.
Roof rats stay active year-round in California, but indoor problems peak from October through January, when the first rains and cooling nights push rodents inside. Citrus and attic activity is most visible in late summer and fall.
A thorough inspection determines the extent of the infestation and exactly how rodents are entering — species identification, entry points, nesting sites, and attractants inside and out. That inspection decides whether trapping, exclusion, or both are needed, and you get honest recommendations either way.
