Ontario Wildlife Ordinances & Trapping Liability
Ontario’s position in the Inland Empire involves a massive transformation of land use. The rapid conversion of former dairy farms, vineyards, and agricultural fields into vast warehouse and logistics centers has severely disrupted local wildlife habitats. Consequently, displaced skunks, coyotes, field mice, and Roof Rats are constantly migrating into residential tracts and older neighborhoods seeking new harborage and food.
The greatest liability for Ontario homeowners isn’t simply property damage; it is the legal exposure of handling this displaced nuisance wildlife illegally. If you rent, attempting DIY trapping or exclusion can violate your lease, while landlords have strict legal duties to perform structural exclusion (see our Ontario Tenant Rights Guide). For severe cases involving financial hardship, explore Ontario Pest Assistance Programs.
The California Catch & Dump Ban: Under California Code of Regulations Title 14, Section 465.5, it is strictly illegal to trap and relocate furbearing mammals (raccoons, skunks, opossums) off your property. Legally trapped animals must be either released immediately on the site where caught or euthanized. Transporting an animal to Cucamonga-Guasti Regional Park or the nearby foothills is a violation of state law.

Unlicensed Trappers & “Humane Relocation” Scams
Avoid “budget” handyman trappers offering cheap trap-and-release services in the Inland Empire. If an unlicensed individual captures a skunk on your property and illegally dumps it in the San Gabriel Mountains or a neighboring city, the Department of Fish & Wildlife can trace the liability back to you. Professionals must hold a CDFW Trapping License AND a Structural Pest Control Board (SPCB) Branch 2 license to seal the access points legally.
Jurisdiction Warning: ARC Inland Empire
As of recent city partnerships, the City of Ontario has joined forces with Chino and Montclair to establish the Animal Resource Center of the Inland Empire (ARC), which now provides full-service animal control and sheltering for Ontario residents, replacing previous county or Humane Society contracts for city limits.
State Law & Municipal Overlap
“(g)(1) Immediate Dispatch or Release. All furbearing and nongame mammals that are legal to trap must be immediately killed or released. Unless released, trapped animals shall be killed by shooting where local ordinances, landowners, and safety permit… (h) Relocation. It is unlawful to relocate any trapped furbearing or nongame mammal.”

Detailed Ontario Authority Directory

West Valley Mosquito and Vector Control District
County / RegionalThe West Valley Vector Control District handles outbreaks of disease-carrying pests across Ontario and surrounding cities. If there is a severe rodent infestation resulting from agricultural/dairy farm displacement into suburban tracts, they can conduct investigations and issue health abatements.
CA Dept of Fish & Wildlife (Inland Deserts Region)
StateCDFW enforces state trapping laws and manages large predator sightings, particularly mountain lions and bears that descend from the San Gabriel Mountains toward northern Ontario and Rancho Cucamonga. They regulate all commercial trapping licenses.
Ontario Wildlife Trapping & Liability FAQ
No. The West Valley Mosquito and Vector Control District actively monitors vector-borne diseases and can force developers to maintain code-compliant sanitation during land clearing, but they will not set traps or apply bait on private residential property. Because rapid land development aggressively displaces field mice and roof rats, homeowners must hire a licensed structural pest control operator to implement a secure exclusion and baiting perimeter.
No. The Animal Resource Center of the Inland Empire (ARC) only responds to active public safety threats. Coyotes are a native and integral part of the Inland Empire ecosystem, utilizing flood control channels and creeks for transit. Routine sightings or yard intrusions must be handled by the homeowner using hazing techniques and physical exclusion (such as coyote rollers). Relocation of coyotes is strictly illegal under California law.
Absolutely not. Releasing trapped wildlife off your property is a direct violation of California Code of Regulations Title 14. Dumping an urban skunk into the foothills or a regional park disrupts the local ecosystem and acts as a massive vector for diseases like rabies and distemper. Trapped animals must be euthanized or released immediately on the exact site where they were caught by a licensed professional.
