Rodent Control and Rat Removal in Fontana, CA

Fontana's rodents come from three directions. Brushy canyons line the north edge, older central blocks have gaps left by years of repairs, and trucks and pallets move through the warehouse district all day. We trap the rodents already inside, close entry points with metal and set up monitoring that fits a home or a business.

San Bernardino County's vector program received 211 service requests from Fontana in 2018, and rodents made up 27% of its primary requests that year.

Canyon lots and hillside streets in north Fontana

North Fontana's tracts run up against open slopes. When police tracked a mountain lion through Hunter's Ridge in 2014, it vanished into a ravine behind homes on Foxborough Drive, a reminder of how close the wild edge is. The county's vector program monitors Hunter's Ridge Park and Jurupa Hills Regional Park, and its 2018 rodent surveys for plague and hantavirus found no infected animals.

Brush, sprinklers and fruit trees draw roof rats, mice and ground squirrels into these yards. Roof rats travel along block walls, fences and branches, so we check wall caps and attic vents, and UC IPM advises pruning limbs within three feet of a roof. Near open land we rely on snap traps and sealing rather than poison, to protect the hawks and owls that hunt there. [8] [13] [31]

Older central houses and mobile homes

In the 92335 ZIP code around central Fontana, about 7,300 homes date from before 1960 and some 1,450 are mobile homes, according to Census estimates. Decades of reroofing, plumbing repairs and add-ons tend to leave torn vent screens, gaps where pipes enter and garage doors that no longer meet the slab. Loose mobile-home skirting gives mice the same easy way under the floor.

San Bernardino County's rodent checklist sets the standard: quarter-inch wire mesh over crawl-space, foundation and attic vents, sealed gaps around pipes and conduits, and garage doors that close tight. A rat can squeeze through a hole the size of a quarter and a mouse through one the size of a dime, the county notes. Our exclusion work uses metal mesh and sheet metal, not foam. [2] [26]

Docks, pallets and cleared lots in the industrial areas

The city's 2025 employment report counts warehousing and storage jobs up about 165% over five years. Each dock door left open between trucks and each stack of pallets against a wall is a likely route for mice and rats. For warehouses we place exterior monitoring stations, check dock seals and sweeps, set traps along interior walls and log every visit.

Fontana also inspects properties for weeds and rubbish twice a year; the fall 2026 round started October 7. When a weedy lot is mowed or disced, rodents sheltering there are likely to head for the nearest buildings. Neighbors of a freshly cleared lot should watch for droppings and gnaw marks. [5] [32]

Signs you need rodent control in Fontana

Droppings along wall caps
Spindle-shaped pellets on top of block walls, fence rails and patio covers where roof rats travel.
Gnawed drip lines and fruit
Chewed irrigation tubing, hollowed citrus or half-eaten tomatoes near the back fence.
Torn pallet wrap at the dock
Shredded stretch film, chewed bags or droppings along racking and dock doors.
Rub marks by the garage door
Dark, greasy smudges at the corners of the garage door and along the base of walls.

How we handle rodent control in Fontana

  1. 1. Walk the lot from wall to roof

    Rodent routes in Fontana often start outside, so the inspection covers walls, slopes and docks as well as the building.

    • Roofline, attic and eave vents
    • Garage door seals and sweeps
    • Block walls, fences and nearby brush
    • Dock doors and racking for businesses
  2. 2. Trap and exclude

    Traps remove the rodents inside while openings are closed with metal so new ones cannot follow.

    • Snap traps in covered, secured spots
    • Quarter-inch mesh over vents
    • Sheet metal at pipe and conduit gaps
    • Exclusion as an add-on or on its own
  3. 3. Clean, monitor and record

    Droppings and nests are removed where reachable, and monitoring continues on the program schedule.

    • Wet cleanup of droppings and nests
    • Sanitizing of affected areas
    • Exterior monitoring stations
    • Dated log for owners, managers and auditors

Rodent Control in Fontana: common questions

Why did rats show up after the lot next door was cleared?

Rodents that lived in tall weeds lose their cover when a lot is mowed or disced, and the nearest buildings are the obvious next shelter. Fontana's weed and rubbish inspections run twice a year, so sealing vents and garage gaps before the clearing starts helps.

How should I clean up droppings in my garage?

Follow the CDC steps the county repeats in its rodent brochure. Air the space out for 30 minutes and wear gloves and a mask. Soak the droppings with disinfectant or a bleach solution for five minutes, wipe them up with paper towels, bag them and disinfect again. Never sweep or vacuum them dry.

Will you use poison near the canyon behind my house?

We start with sealing and snap traps. Near open slopes and canyons, a poisoned rodent can be eaten by a hawk, owl or coyote. We keep rodenticide out of those spots and explain where each trap sits before we leave.

Can you service a warehouse without slowing down shipping?

Yes. Visits are scheduled around shifts, stations sit along exterior walls and near interior racking, and dock seals get checked each time. Every visit is logged with findings and activity counts that you can hand to auditors or customers.

My landlord has not fixed a mouse problem. What can I do?

Report it to the owner or manager in writing and keep a copy. San Bernardino County's rodent brochure says renters can contact its vector program at (800) 442-2283 if an owner does not address a pest issue. We also work directly with landlords and managers, with written findings that support their duties under California Civil Code 1941.1.

Do mobile homes need a different approach?

The main difference is the skirting. Loose or broken panels let mice and rats under the floor, where they reach plumbing and duct openings. We check the skirting, close gaps with metal and seal the pipe and duct penetrations above it.

Roof rats overhead, Norway rats underfoot, mice in the pantry

Three rodents account for nearly every call in Fontana, 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.

Inspection, trapping and monitoring: the PesPro rodent sequence

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.

Preparing for the first visit, and what the first weeks look like

Before the technician arrives at your Fontana 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.

The 30-day guarantee for rodents, the quote and same-day calls

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 Fontana 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.

Service records for Fontana managers, and prevention that holds

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 Fontana 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.

  • Trim limbs touching the roof; pull ivy off fences and walls
  • Pick up fallen citrus and avocados; feed pets only what they finish
  • Tight trash lids; stored items 18 inches off the ground
  • Seal gaps over a quarter inch with metal mesh, sheet metal or concrete
  • Cover a car parked outdoors for weeks; rats chew engine wiring

Planning rodent control at your Fontana property

How do I know whether it is rats or mice?

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.

Why has nothing been caught yet?

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.

Does the program seal the holes rodents use?

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.

What does the 30-day guarantee cover for rodents in Fontana?

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.

Is poison used inside the house?

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 is same-day rodent service worth the extra fee?

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.
