This past week, a Whole Foods Market in Cupertino shut its doors following an alarming rodent and cockroach infestation. Health inspectors with the Santa Clara County Department of Environmental Health found repeated violations, including live cockroaches in kitchen areas and fresh rodent droppings in food preparation zones. Conditions that posed an “imminent threat to health and safety.” It was not the first time the store faced issues, with multiple closures earlier this month in the deli and bakery departments for similar violations.
Unfortunately, this is not an isolated incident. In Los Angeles County, rodent infestations have become a growing concern. In 2022, Governor Gavin Newsom acknowledged a resurgence of typhus, a disease spread through infected rats, calling it a “medieval disease” after 171 cases were confirmed. This past month, Newsweek had a story entitled, “California Has A New Rat Problem.”
In the Newsweek story, Mike VanFossen, the assistant vice provost at Residential & Dining Enterprises (R&DE) at Stanford University, stated, “that a population increase of rodents has occurred statewide following the legislation passed months ago [In September 2024, the California legislature passed the Poison-Free Wildlife Act, which bans some rat poisons. In the months since, some people have claimed an increased rodent population has been to contend with].”
Chris Wible, director of technical services for Terminix, told Newsweek, “Nationwide, we have seen an increase in rodent pressure and populations.” He also noted that urbanization and climate are contributing factors. “We are certainly seeing that in California as well, and legislation is a contributing factor to that by eliminating available tools to mitigate rodent populations.”
These examples reinforce a simple truth: effective pest control is essential to protecting public health, maintaining sanitary business environments, and keeping our economy functioning.
Restaurants, grocery stores, housing units, and food warehouses depend on access to pest management tools to remain open and safe. Without them, communities risk outbreaks of rodent-borne illnesses like leptospirosis, hantavirus, rat-bite fever, and salmonella. Diseases that can have severe consequences for vulnerable populations.
As rat populations surge, fueled by food access in homeless encampments and aging infrastructure, our need for modern, effective pest control grows more urgent. Yet, some regulatory trends threaten to eliminate or restrict the tools professionals rely on to protect homes and businesses.
We must ensure local governments, regulators, and the public understand the consequences of limiting pest control tools. Protecting human health, economic stability, and community safety begins with acknowledging the importance of science-based pest management. The tools work. And now, more than ever, we need them.
