What is a perimeter application?

• A. A method to spray inside living spaces.
• B. Treatments applied only to water sources.
• C. A technique for personal protective equipment.
• D. Perimeter treatments form a barrier on exterior surfaces -house, exposed foundation, soil and nearby plant material

Answer: (D)

Perimeter applications are exterior barrier treatments designed to stop pests from reaching the indoor space. They’re applied around the outside of the structure—around the foundation, soil, and nearby vegetation—creating a treated boundary that pests must cross to get inside. This approach provides residual protection and reduces entry by mosquitoes and ticks as they move around the exterior environment. Interior spraying targets living areas, which isn’t what perimeter application describes. Treatments aimed only at water sources focus on aquatic habitats, not a barrier around the home. PPE is about protective gear for people, not a treatment method. So forming a barrier on exterior surfaces around the house and its immediate surroundings best matches the concept.
