“Follow the science” is still a phrase people use, but it is too often applied selectively. Few issues show this better than the debate over sulfuryl fluoride, the fumigant used in whole-structure pest control. Strip away the rhetoric, and what remains is a clear scientific record: sulfuryl fluoride is a tool used by pest control operators, tightly regulated and proven to protect homes, apartments, and historic buildings for more than half a century.

Whole-structure fumigation exists for one reason. Some pests live entirely inside walls, framing, attics, and furniture, where sprays, foams, and spot treatments cannot reliably reach them.

Drywood termites, wood-boring beetles, and other hidden pests do not forage outside. If even a small portion of the population survives, the infestation returns.

In pest control, partial effectiveness is not success, especially when there is a full infestation, and the pests are embedded in the wood. Full elimination is the only outcome that actually solves the problem.

Sulfuryl fluoride makes this possible because of how it works. It is a gas that evenly penetrates all enclosed spaces within a structure. This uniform distribution allows it to reach pests wherever they are hiding, without relying on repeated applications or invasive demolition. After the treatment, the structure is aerated, and the fumigant dissipates. It does not leave residue behind.

This process is not casual or unregulated. Sulfuryl fluoride has been used safely for more than 50 years under extensive oversight by the U.S. Environmental Protection Agency and the California Department of Pesticide Regulation. Before approval, the compound underwent rigorous toxicological testing, exposure modeling, and environmental review. Those evaluations have been updated repeatedly as science and monitoring tools improved.

Today, structural fumigation is performed only by licensed professionals, following strict federal and state protocols. Gas concentrations are continuously measured during treatment. Clearance testing confirms that structures are safe to reenter.

Notification, training, equipment standards, and enforcement are all part of the regulatory framework. This is not guesswork. It is a controlled, verified application guided by decades of data.

Much of the misinformation surrounding sulfuryl fluoride ignores this context.

Science helps solve a problem once and completely, which is often the lower-impact option.

Following the science means trusting evidence, not fear. It means recognizing that whole-structure fumigation remains a key option for pest control operators because it works, is monitored, and has earned its place through decades of demonstrated safety and effectiveness. In housing, preservation, and affordability, certainty still matters.
