Gopher Problems in Ontario HOA Communities and Near Parks

Ontario sits at the geographic crossroads of the Inland Empire, bordering Rancho Cucamonga, Fontana, Eastvale, and Chino — and gopher activity flows freely across all of these borders. The city's combination of established older neighborhoods in the north, the rapidly growing Ontario Ranch master-planned community in the south, and multiple large parks and school campuses throughout creates diverse but persistent gopher pressure across the entire city.

The Main Gopher Sources in Ontario

Cucamonga-Guasti Regional Park is a 150-acre regional park on the eastern edge of Ontario along Archibald Avenue. The park's irrigated athletic fields, picnic areas, and maintained grounds support a substantial gopher population that pushes into the surrounding residential neighborhoods. Properties along Archibald Avenue and the streets east of the park report some of the most consistent activity in Ontario.

Ontario Ranch is one of the largest new master-planned community developments in California, with thousands of new homes, extensive HOA greenbelt systems, and community parks spread across thousands of acres in southern Ontario. The greenbelt infrastructure that connects these communities — while visually attractive — functions as a gopher highway. As development has expanded across previously agricultural Chino Valley land, displaced gopher populations from former farmland have migrated into the new residential areas. Ontario Ranch homeowners are experiencing this agricultural-to-residential transition firsthand.

College Park and Creekside communities in northern Ontario border older agricultural parcels and open drainage corridors that have sustained gopher populations for decades. The Cucamonga Creek and Chino Creek corridors running through the city provide riparian gopher habitat that connects natural populations to residential areas.

Ontario Airport and industrial corridor land bordering residential areas — particularly the large maintained green spaces around the airport and the landscaped buffers along major industrial facilities — harbor gopher populations that are never systematically managed. These green buffer zones function identically to golf courses and parks as gopher reservoirs adjacent to residential neighborhoods.

School campuses throughout Ontario — including Ontario High School, Colony High School, and the many elementary and middle school campuses across the city — maintain irrigated athletic fields year-round. Each campus functions as a neighborhood-level gopher source, feeding animals into the surrounding residential blocks through the school year and over summer break when activity is unchecked.

The Ontario Ranch Specific Challenge

Ontario Ranch homeowners face a distinct version of the gopher problem. Much of the land the community is built on was previously active agricultural land — citrus, dairy, and row crop operations that hosted established gopher populations for generations. Development displaced those populations, but it did not eliminate them. Gophers from former agricultural areas pushed into the first wave of residential development, and the HOA greenbelt systems that connect the new communities have allowed those populations to distribute across a wide area. New homeowners in Ontario Ranch should expect ongoing activity, particularly in the earlier-developed sections closer to remaining agricultural parcels.

No Poison in Ontario's Family Communities

Ontario's rapid residential growth means the city has a large population of young families with children and pets. Rodent Guys uses only traps and carbon monoxide — no rodenticide bait. This is especially important in dense HOA communities where children play in greenbelts and dogs and cats roam freely. Our methods leave no residue and pose zero secondary poisoning risk.
