California is facing a rodent crisis that affects not only property damage but also public health, safety, and economic liability. Mike VanFossen, Assistant Vice Provost at Stanford University, noted to Newsweek that Californians are bearing the brunt of misguided legislative decisions.
Rodents aren’t just nuisances. They spread deadly diseases like hantavirus, leptospirosis, and salmonella. Their droppings contaminate food surfaces, their gnawing destroys insulation and wiring, and they are, in some cases, the source of house fires. Despite this, recent policy choices are making it harder, not easier, to control these threats.
In September 2024, California passed the Poison-Free Wildlife Act, banning several rodenticides. This move, championed under the banner of wildlife protection, has had a very different real-world impact: exploding rodent populations. Mike VanFossen, Assistant Vice Provost at Stanford University, confirmed a statewide increase in rodent activity following the legislation. Orkin and Terminix pest control experts agree that the loss of key tools has stripped professionals of their ability to effectively contain rodent threats.
Rodents adapt quickly, reproduce rapidly, and infiltrate buildings through holes as small as a quarter. Without access to a full arsenal of pest management tools, prevention becomes a guessing game, and control becomes nearly impossible in some urban environments.
California cities are now topping national lists for rodent infestations; Los Angeles ranks No. 2, San Francisco No. 4, San Diego ranks No. 18, and Sacramento sits at No. 20 on Orkin’s 2024 “Rattiest Cities” list. This isn’t just a seasonal inconvenience; it’s a year-round problem that affects families, renters, businesses, and farmers alike.
The rise in rodent sightings and infestations is not merely anecdotal; it is being reported by professionals on the frontlines.
Pest control professionals need access to viable, science-based tools to perform their jobs. Legislators and regulators must understand that when effective solutions are removed, the pest control industry suffers, as does every Californian.
Let’s stop hindering the people who protect our homes, schools, and businesses. Rodent control isn’t about politics, it’s about public health.
