Pesticide Registration

Fogger and Mister Final Signed Letter

We sent this letter to companies holding a registration for one or more antimicrobial pesticide products that make claims to provide control of public health microorganisms when applied by fogging and/or misting methods. We seek to make sure that fogger/mister products are effective as claimed and are labeled in a manner that will prevent unreasonable adverse effects from occurring with regard to human health and the environment.

As explained in the letter, we are concerned that fogging/misting products may not be as effective as claimed, and we want to ensure that these fogging/misting products are accurately labeled. By this letter, we are asking companies either to provide existing efficacy data, or to commit to provide new data, that address the public health claims for the fogger/mister products. Alternatively, the registrant may elect to revise the labeling of the affected products and registrations to delete the public health claims for the fogger/mister products.

The letter further describes the ways in which the company may respond.

Please direct questions or comments to the Antimicrobials Ombudsman (OPP_AD_Ombudsman@epa.gov).
