EPA is considering a proposal to codify product performance data requirements to support registration of products claiming efficacy against three categories of invertebrate pests: those identified to be of significant public health importance (e.g., ticks, mosquitoes, cockroaches, etc.), wood-destroying insects (e.g., termites), and invasive invertebrate species (e.g., Asian long-horned beetle). The two latter categories are considered to be of significant economic importance. Product performance data (efficacy studies) document how well the product performs the intended function (such as killing or repelling) against an invertebrate pest. In preparation for this rulemaking, EPA has been seeking expert opinion and recommendations from the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP). As a result of the March 2013 SAP meeting, the SAP provided recommendations for EPA to consider as (1) this future proposal concerning product performance data requirements and (2) new or revised testing guidelines for pesticide products claiming efficacy against invertebrate pests are being developed. In May 2018, EPA presented to the SAP for review and consideration a draft of the Product Performance Test Guidelines for Red Imported Fire Ants and a draft of the Product Performance Test Guidelines for Premises Treatments. The Agency is also considering whether to codify the requirement that the results of the efficacy data must support the product label claim. The Pesticide Registration Improvement Extension Act of 2018 (PRIA 4) requires EPA to publish the final product performance data requirements no later than September 30, 2021.
