EPA Delays PFAS Pesticide Approvals Amid Growing Health Concerns

The Environmental Protection Agency is holding back dozens of approvals for PFAS-containing pesticides, commonly called "forever chemicals," as federal regulators grapple with mounting pressure from public health advocates and state-level legislative action.

The delay marks a notable departure from the EPA's broader deregulatory push under Administrator Lee Zeldin, who has otherwise moved aggressively to roll back environmental regulations. According to reports, the agency is proceeding cautiously to avoid provoking backlash from the Make America Healthy Again movement and its influential supporters.

What Are PFAS Pesticides?

Per- and polyfluoroalkyl substances, or PFAS, are a family of synthetic chemicals prized for their resistance to heat, water, and oil. These same properties that make them useful in pesticides—enhancing spreading, durability, and weather resistance—also mean they do not break down in the environment or the human body.

The EPA has approved approximately 70 active-ingredient PFAS pesticides nationwide. In California alone, the Department of Pesticide Regulation has allowed 53 of these products for agricultural and commercial use. Despite representing only 5 percent of state-registered active pesticide ingredients, PFAS pesticides account for 15 percent of pesticide residues detected on California-grown produce.

California Takes the Lead

While federal regulators delay, California is moving toward an outright ban. Assembly Bill 1603, introduced by Assemblymember Nick Schultz and cosponsored by the Environmental Working Group, would prohibit the California Department of Pesticide Regulation from registering any new pesticide containing intentionally added PFAS.

If passed, the legislation would classify PFAS as restricted materials by July 2028. The manufacture and sale of pesticides containing certain PFAS would be prohibited by January 2030, with a complete ban on all PFAS pesticides taking effect by January 2035.

"The EPA has approved 70 active-ingredient PFAS pesticides, and the California Department of Pesticide Regulation has allowed 53 of these pesticides to be used in the state," Schultz's bill notes. "The nation's top agricultural producer could ban pesticides with PFAS after researchers found the 'forever chemicals' on 40 percent of the conventional produce grown in the state."

Health and Environmental Risks

The nickname "forever chemicals" is not hyperbole. PFAS accumulate in soil, water, and living tissue over time. Research has linked PFAS exposure to various health problems including immune system disruption, thyroid disease, and certain cancers.

For pest control operators and agricultural applicators, the implications extend beyond regulatory compliance. The chemicals they apply today could persist in the environment—and potentially in their clients' food and water—for decades.

The Environmental Working Group's 2026 Shopper's Guide to Pesticides in Produce found that 75 percent of conventional produce samples tested positive for pesticide residue. While the levels detected are generally below EPA thresholds for acute danger, critics argue that the agency's safety assessments do not adequately account for cumulative, long-term exposure to persistent chemicals like PFAS.

Industry Impact and Uncertainty

For the structural pest control industry, which generates approximately $6.5 billion annually across more than 19,000 firms nationwide, the regulatory uncertainty creates operational challenges. Companies must balance effective pest management with evolving chemical restrictions and growing consumer demand for "green" alternatives.

The EPA's delay on PFAS approvals suggests the agency is weighing these competing pressures. While the pause provides temporary relief from new forever chemical products entering the market, it also leaves the industry in limbo regarding which chemistries will remain available long-term.

What This Means for Texas

Texas, with its massive agricultural sector and extensive pest control industry, has significant exposure to PFAS pesticide regulations. The state's cotton industry alone—already facing threats from invasive pests like the cotton jassid—relies heavily on chemical protection. Any restrictions on available chemistries could force rapid adaptation.

Pest control operators should monitor both federal and state developments closely. While Texas has not yet introduced legislation matching California's proposed ban, regulatory trends often spread from West Coast to nationwide adoption.

Looking Forward

The convergence of federal delay and state-level action suggests a pivotal moment for pesticide regulation in the United States. Whether the EPA eventually releases its hold on PFAS approvals or tightens restrictions will significantly shape the tools available to pest management professionals for years to come.

For now, the message is clear: forever chemicals are facing unprecedented scrutiny, and the pest control industry's relationship with PFAS is entering a new, uncertain phase.

As California moves toward prohibition and federal regulators weigh their options, pest control operators and agricultural producers should prepare for a future where PFAS-free alternatives may become not just preferable, but mandatory.
