Between the working waterfront, the ocean bluffs and streets of century-old houses, San Pedro gives rats more than one kind of home. We find how they get in, trap the ones inside, close the openings with durable materials and clean up after them.
In ZIP 90731, about 6,100 homes were built before 1940, and the Vinegar Hill historic district protects houses dating from 1886 to 1927.

Vinegar Hill's protected houses date from 1886 to 1927, and across ZIP 90731 Census estimates count about 6,100 homes built before 1940 and 1,800 more from the 1940s. Wood houses of that age tend to have porch skirting with gaps, worn crawl-space vents and pipe holes left from decades of plumbing work.
The city's rental inspectors look for missing window and foundation vent screens on their four-year rounds, the same kind of gaps rodents use. Our Rodent Exclusion work closes them with hardware cloth, galvanized mesh and sheet metal rather than foam, which rats chew through. On historic facades we agree on placement first and keep repairs paintable and discreet. [3] [1] [9]
The Port of Los Angeles runs 43 miles of waterfront, 25 cargo terminals and 15 marinas with 3,736 recreational slips and dry docks. Places like these are likely to offer rats water, shelter and scraps, and the neighborhoods along Harbor Boulevard sit right beside them.
UC IPM describes two species to tell apart. The Norway rat burrows along foundations, under rubbish and beneath woodpiles. The roof rat, also called the ship rat, climbs and nests in trees, attics and dense plants, and prefers warm coastal settings. Burrows at ground level and droppings in the attic call for different traps and different seals.
Restaurants, markets and storage buildings near the water can set up a recurring rodent program with trapping, exclusion and written logs for county inspectors. [4] [13]
White Point Nature Preserve and Point Fermin Park keep open ground along Paseo del Mar. In ZIP 90732, about half of the homes are detached houses. UC IPM advises thinning dense vegetation, pulling climbing ivy off fences and walls and keeping tree limbs at least six feet from the roof.
Near open space we rely on snap traps in secured stations and on sealing. Rodenticide stays out of spots where hawks, owls or coyotes could feed on a poisoned rat. Raccoons, skunks, opossums and coyotes themselves are handled through LA Animal Services, not by PesPro. [7] [8] [2] [13] [15]
Fleas from rats, stray cats and opossums spread flea-borne typhus, which reached a record 220 cases county-wide in 2025, with 109 more reported by late September 2026. No public report places cases in San Pedro. After trapping, we remove droppings and nesting debris where accessible, sanitize the area and set monitoring. Pet owners should keep year-round flea control in place. [22] [23]
From the slope or alley to the roofline, we trace burrows, runways and openings around the whole property.
Snap traps in secured stations for rodents already inside, plus Rodent Exclusion that seals gaps with hardware cloth, galvanized mesh and sheet metal.
We remove droppings and nesting debris where accessible, sanitize the area and set monitoring, or enroll the property in an ongoing rodent program.

Read the originalThey can. Norway rats burrow and travel along foundations, rubbish and drainage, and roof rats move through trees, ivy and utility lines. Homes close to the waterfront, marinas or food businesses are likely to see more pressure, so we check both ground level and the roofline.
That is often a roof rat feeding spot. UC researchers list snails, slugs and fruit among the foods roof rats prefer. Look for droppings nearby, then call so we can find where they are getting in.
Yes. We fasten hardware cloth behind the lattice and along the base of the porch, secure it to the framing and leave it paintable. On historic homes we agree on placement with you before starting.
We avoid it. Near the preserve and other open ground we use snap traps in secured stations and exclusion, so hawks, owls and coyotes are not exposed to poisoned rodents.
The Los Angeles Housing Department inspects every multi-family rental property on a four-year cycle, and its inspectors look for missing window and foundation vent screens among other habitability items. It also responds to tenant complaints.
Yes. We set up recurring service with trapping, exclusion and monitoring, schedule visits outside business hours and keep a written log that managers can show a county health inspector.
Three rodents account for nearly every call in San Pedro, and they live differently. Roof rats climb into attics, trees, ivy and fence tops and eat backyard citrus and avocados on the tree. Norway rats burrow along foundations and under sheds. House mice live indoors, rarely more than about 30 feet from the nest.
Mild winters mean none of them hibernate, and the first cool nights and autumn rains push rats indoors. Older housing supplies the openings: any gap wider than a quarter inch at a vent screen, eave board, utility line or door threshold is enough.
The inspection covers attic, crawl space, garage, kitchen and yard, reading droppings, rub marks, gnawing and burrows to confirm which species is active and where it travels. Traps go on those routes: fastened to beams for roof rats, tight against walls for Norway rats, closely spaced for mice.
Indoors the program leans on snap traps rather than poison, following LA County guidance, because a poisoned rodent that dies inside a wall leaves odor and flies. Monitoring visits reset traps, remove what was caught and compare activity with the last visit so placements move as the rodents do. Sealing openings is Rodent Exclusion, a separate add-on.
Before the technician arrives at your San Pedro address, clear access to the attic hatch, under-sink cabinets and garage walls, and raise stored boxes so runways show. Pick up fallen fruit and bring pet food in at night. Do not set out poison first: it hides evidence and risks a dead rat in the wall.
Rats are wary of new objects and may ignore traps for days or weeks, so early visits leave traps baited but unset until the bait disappears. Catches and quieter nights follow; monitoring continues because new rats replace caught ones while fruit, ivy and open gaps remain. Never sweep droppings dry: glove up, soak with disinfectant, wipe, double-bag.
Every PesPro service carries a 30-day guarantee, and rodents sit in the strongest tier with bed bugs and cockroaches: if rats or mice reappear within 30 days of a service, PesPro returns for a third visit at no extra cost, where other pests would pay 30% of the original price for a return visit.
The quote is free and written after the inspection. Rodent control is priced by property size, activity found and how often visits are needed; exclusion is priced separately by the number and type of openings to seal. Trapping alone or sealing: the inspection says which.
Same-day service is available for an extra fee. It makes sense when rats are inside the living space, when wiring has been gnawed, when a San Pedro food business has an inspection pending, or when a tenant complaint has started a habitability clock. Call (323) 472-5329 any hour, or the office and WhatsApp line, (323) 303-3522, in business hours.
The LA County Department of Public Health reported record flea-borne typhus cases in 2025, ties the fleas to rats, free-roaming cats and opossums, and recommends controlling fleas before or alongside trapping where typhus is a concern. For landlords, California Civil Code 1941.1 lists vermin-free premises among habitability duties, so dated service records matter.
PesPro's program keeps digital service logs that San Pedro owners, HOA boards and inspectors can open any time, same-day compliance documentation when a citation is at stake, tenant-notification templates and consolidated invoicing for multi-site portfolios. Over 15 years the company has protected more than 10,000 properties, more than 500 of them multi-unit.
A house mouse weighs about half an ounce and stays within 30 feet of its nest. Rats weigh 5 to 18 ounces: a roof rat's tail is longer than its body and it favors attics; a Norway rat is stockier and burrows.
Rats avoid new objects and can ignore a trap for days or weeks; floor traps also miss roof rats traveling beams and pipes. If a trap line stays untouched past the second visit, placements move.
Sealing is Rodent Exclusion, a separate add-on and structural work: vents, utility penetrations, foundation cracks and roofline gaps closed with metal mesh, sheet metal or concrete. The inspection lists the openings found and quotes exclusion on its own line.
If rodent activity reappears within 30 days of a service, PesPro returns for a third visit at no extra cost. The exact wording is on your quote, next to the monitoring schedule.
The default indoors is snap traps, because a poisoned rodent can die inside a wall or ceiling. Bait stations are locked, tamper-resistant and placed where children and pets cannot reach them. Tell the technician about pets before placement.
When droppings appear where food is prepared for infants or vulnerable adults, when rats are in living areas, or when a health inspection or tenant complaint sets a deadline. For attic noises alone, a regular appointment follows the same plan.
