Pest Control Services in Fontana, CA

The city's own history traces Fontana to 1905, when A.B. Miller bought about 17,000 acres then called Rosena and turned them into citrus orchards, poultry farms and cattle land. Henry J. Kaiser opened his steel mill on the edge of town in 1942, and it rolled steel plate for Liberty and Victory ships during World War II. The mill stopped operating in 1984, and the Auto Club Speedway was built on its site in the mid-1990s.

Growth has not stopped since. Census estimates put the median Fontana home at 1989: about 7,700 homes predate 1960, some 14,500 were built in the 1980s alone, and roughly 19,000 have gone up since 2000. Houses from the steel decades are the likeliest to have worn foundation vents, tired garage seals and patched plumbing. Newer homes are tighter, yet pests still find the gaps around pipes, vents and garage doors. [4] [1]

ZIP code areas give a closer look, although they do not follow city limits exactly and take in some unincorporated county pockets. In 92335, around central Fontana, the median home was built in 1977, more than a quarter of homes predate 1960 and about 52% of households rent. Roughly 7,000 homes there sit in buildings of five or more units, and about 1,450 are mobile homes.

North Fontana's 92336 looks like another city. Its median build year is 1999, about half its homes date from 2000 or later, nearly nine in ten are detached houses and only about one household in five rents.

That split shapes what we expect to find. In central Fontana the likely calls are German cockroaches and bed bugs moving between apartments, plus rodents under older houses and mobile-home skirting. In the north, newer houses back onto slopes and open land, so mice, rats, spiders and wasps arriving from outside are more typical. [2] [3]

A 2025 employment report prepared for the city by Beacon Economics calls logistics one of Fontana's most specialized industries. Transportation, warehousing and utilities accounted for about 9,500 jobs in mid-2024, a concentration 3.3 times the state's. Warehousing and storage employment was up roughly 165% over five years, despite a dip in the latest year.

Many of those buildings sit near homes and schools. In 2022 the state attorney general settled a lawsuit over a warehouse of about 200,000 square feet at Slover and Oleander, on the southern edge of Jurupa Hills High School. The city's sustainability ordinance now requires tall walls and landscape buffers beside sensitive uses. It also calls for plug-in power at loading docks for refrigerated trucks, a sign of how much food moves through.

For pest control, that means pallets, dock doors and break rooms. UC IPM lists warehouses among the buildings German cockroaches infest, and dock doors left open between trucks are likely entry points for mice and rats. Our commercial programs combine exterior monitoring, door seals, interior traps and a dated log for audits. [5] [7] [6] [30]

Fontana's north side climbs toward the mountains. In August 2014, police tracked a mountain lion through the Hunter's Ridge community, on the 4200 block of Foxborough Drive, until it slipped into a canyon behind several homes. The Fontana Herald News reported that lions had been seen in the hilly northern neighborhoods of Fontana and Rancho Cucamonga several times over the previous year.

At the south end, Martin Tudor Jurupa Hills Regional Park on Sierra Avenue has trails into the hills. The county's vector program lists that park, Hunter's Ridge Park, Shadow Park and Veterans Park among the Fontana sites it monitors. Its 2018 rodent surveys for plague and hantavirus found no positive animals.

Homes that back onto canyon or hillside brush are likely to see more rodents, ground squirrels, spiders and wasps, so we lean on sealing and snap traps there. Large animals such as coyotes or mountain lions are a matter for Fontana Police Dispatch, which handles roaming and dangerous animal calls. [8] [9] [13] [10]

Fontana is one of the valley cities where San Bernardino County's Mosquito and Vector Control Program provides service, at (800) 442-2283. In 2018, 211 of its 1,299 service requests came from Fontana, and block surveys after mosquito complaints included 711 Fontana property inspections, more than in any other city.

West Nile has a local record. In July 2017 the county reported positive sentinel chickens in Fontana and San Bernardino and a positive mosquito sample drawn from Fontana, Rialto and Redlands. State tables list West Nile–positive dead birds from Fontana every year from 2013 through 2017. None appeared from 2018 through 2025, then one turned up in 2026, when the county logged 19 in all.

The state also lists Aedes aegypti as present in Fontana; it bites by day, and the county notes that water the size of a bottle cap can breed mosquitoes. PesPro does not offer mosquito control, so call the county about standing water or a neglected pool. Statewide, health officials called 2026 the most active West Nile season in five years.

On May 27, 2020, a stolen car fleeing Fontana police crashed into a tree on Mango Avenue near Miller Avenue and split open a large beehive. At least three officers were taken to a hospital as a precaution, and the street stayed closed until vector control staff removed the bees.

San Bernardino County advises treating every honey bee colony as if it were Africanized, since only lab tests tell them apart. Africanized bees defend a hive in greater numbers and deliver about ten times as many stings. Fontana opens cooling centers when the forecast reaches 100 degrees, and hot spells likely send bees and wasps hunting for water around homes. We remove wasp nests and relocate live honey bees when feasible. [19] [20] [21]
