TX Structural Pest Exam Domains 2027: Complete Guide to All 8 Content Areas

Understanding the TX Structural Pest Exam Structure

The Texas Structural Pest Control certification exam has undergone significant changes with Metro Institute taking over as the testing provider beginning May 19, 2025. This comprehensive examination system encompasses eight distinct domains, each targeting specific aspects of structural pest control knowledge and application. Understanding these domains is crucial for both technicians and certified applicators seeking to advance their careers in the pest control industry.

The examination format consists of closed-book multiple choice questions, with each exam containing 50 questions that must be completed within 75 minutes. Candidates receive same-day final scores from Metro Institute, which are then transmitted to the Texas Department of Agriculture. With a current pass rate of 60.33%, thorough preparation across all domains is essential for success.

Domain 1: General Standards

The General Standards domain serves as the foundation for all structural pest control certifications. This mandatory domain covers fundamental principles that apply across all pest control specializations, making it the most comprehensive and critical section of the examination program.

Core Topics and Concepts

General Standards encompasses regulatory compliance, safety protocols, pesticide laws, and basic entomology. Candidates must demonstrate understanding of federal and state regulations, including EPA guidelines, FIFRA requirements, and Texas-specific statutes. The domain also covers integrated pest management (IPM) principles, which have become increasingly important in modern pest control practices.

Key areas include pesticide classification systems, label interpretation, personal protective equipment (PPE) requirements, and environmental protection measures. Understanding these concepts is crucial because they apply to all subsequent domains and form the basis for safe, legal pest control operations.

For detailed study guidance, our complete General Standards study guide provides comprehensive coverage of all topics within this essential domain.

Domain 2: Pest Control

The Pest Control domain focuses on the identification, biology, and management of common structural pests excluding termites, which are covered separately in Domain 3. This broad category encompasses insects, rodents, and other pests commonly encountered in residential and commercial structures.

Target Organisms and Control Methods

This domain covers a wide range of pests including ants, cockroaches, flies, stored product insects, occasional invaders, and vertebrate pests. Candidates must understand pest biology, behavior patterns, identification characteristics, and appropriate control strategies for each group.
