  • Industrial, Institutional, Structural and Health Related Pest Control Category
    • Applicators in this category must demonstrate a practical knowledge of a wide variety of pests including their life cycles, types of formulation appropriate for their control, and methods of application that avoid contamination of food, contamination of habitat, and the exposure of people and pets. Since human exposure, including babies, children, pregnant women, and elderly people, is frequently a potential problem, applicators must demonstrate practical knowledge of the specific factors that may lead to a hazardous condition including continuous exposure. Because health related pest control may involve outdoor applications, applicators must also demonstrate practical knowledge of environmental conditions particularly related to this activity.
  • Wood Preservative Subcategory
    • Applicators must demonstrate a practical knowledge of the pests involved with wood products, including their life cycles, wood degradation, the pesticides available for controlling these problems, and methods of application including pressure, non-pressure and brush-on treatments. Since there is concern regarding the potential for environmental contamination as well as acute and chronic health problems from applicator exposure when using certain woodtreating pesticides, specific emphasis will be placed upon demonstrating a practical knowledge of the product use, precautions which are required and found on the labels and labeling of these pesticides and include protective clothing and equipment, sanitation procedures, disposal procedures and environmental precautions. Since treated wood products present potential environmental problems and acute and chronic exposure problems to the users and the general public, whether or not they come into direct contact with the treated wood, applicators must demonstrate a practical knowledge of the consumer information covering use, site, and handling precautions which are found in the Consumer Information Sheets of products registered for pressure treatment and in the labeling for products registered for sap and stain control, ground line treatment of utility poles, and home and farm use (including railroad tie repair).
