Registration of Pesticide Products
Minimum Rates Established for Pre-Construction Termiticide Treatments

On October 1, 1996, the U.S. EPA published Pesticide Regulatory Notice (PR-Notice) 96-7. This notice, which went into effect on January 1, 1998, required a number of changes in the labeling of termite control products. However, among all of the changes the statement: "Pre-Construction Treatment: Do not apply at a lower dosage and/or concentration than specified on this label for applications prior to the installation of the finished grade," is perhaps the most important. It states clearly and simply what is required.

Most structural pest control companies are complying with applying the full rate and volume allowed by the label, in compliance with the new requirement. Unfortunately, some companies are cutting corners by continuing to apply less than the full rate and volume. In doing so, these companies are shortchanging consumers and creating an economic disadvantage for those companies complying with the new requirements.

Pesticide investigators will continue to give special attention to pre-construction termiticide applications. Investigators may ask applicators for permission to examine company records of recent jobs and may take soil samples at job sites for residue analysis. These soil samples will be taken and analyzed in accordance with the Association of Structural Pest Control Regulatory Officials' (ASPCRO) Soil Sampling Procedure and Guidance Document for Soil Samples. The table gives the lowest residues, in parts per million (ppm) expected 180 days after treatment for commonly used termiticides.
