Roof Rat and Rodent Control in Upland, CA

UC IPM's guide to rats describes roof rats as agile climbers that nest in trees, shrubs and ivy and eat avocados and citrus while the fruit still hangs. On oranges they leave hollowed rinds; on lemons they often strip the peel and leave the flesh. They routinely travel 300 feet or more, so the rats eating your fruit may nest a few yards away.

In a city whose early economy rested on lemon groves, backyard citrus is a likely draw. We look for chewed fruit, droppings under the canopy and runs along fence tops and wires. Then we recommend picking up fallen fruit, thinning ivy and cutting limbs back six feet from the roof. [33] [5]

The city's nine historic districts date from the late 1880s to the 1930s, from Victorian Row to the Arrow/Laurel bungalows. Census estimates count about 1,380 homes built before 1940 and 4,900 before 1960. Houses of that age often have raised floors with foundation vents, attic louvers and eaves where boards have shrunk apart.

UC IPM's exclusion standard is to seal every hole wider than a quarter inch and to cover vents with 16- or 18-gauge, half-inch galvanized mesh, never chicken wire. On historic homes we choose fasteners and placements that leave original trim intact and can come off later. [5] [1] [33]

North of the city center, ZIP code 91784 is 89% detached houses. It climbs into San Antonio Heights, which the county describes as a historic subdivision beside the Angeles National Forest. Residents there value large lots, trees and wildlife, which also give rodents cover.

UC IPM notes that California has native woodrats, or pack rats, which eat fruit and nuts like roof rats but have furry tails. On brushy lots either can move into garages, sheds and attics. Clearing brush and stacking firewood away from walls, already wise on a fire-prone foothill lot, takes that cover away. [3] [6] [33]

The West Valley Mosquito and Vector Control District, which serves Upland, offers rodent inspections that look for rodents and access points around a property's perimeter. When trapping and sealing are needed, that work generally falls to owners and licensed companies.

UC IPM reports that California now bars most uses of anticoagulant rodenticides, so our plans lean on snap traps in covered stations and permanent exclusion. After trapping, we remove nests and droppings we can reach, following the district's advice to wet them down rather than sweep. [13] [33] [12]

Three rodents account for nearly every call in Upland, 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 Upland 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 Upland 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 Upland 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.
