Treatments may include interior and exterior applications depending on infestation. What does this imply for service planning?

• A. Interior applications are used exclusively.
• B. Both interior and exterior applications may be used depending on the infestation.
• C. No interior or exterior planning is needed.
• D. Only exterior applications will be used regardless of infestation.

Answer: (B)

Planning must account for where pests are active and how they’re accessed. If the infestation is inside, interior applications target the pests where they live, hide, or enter—think cracks, voids, and spaces inside walls or cabinets. If the issue is mainly outside or you’re trying to create a barrier, exterior applications treat the perimeter, foundation, and surrounding landscape to prevent pests from moving indoors.

Because infestations can involve both indoors and outdoors, the best service plan typically includes a mix of interior and exterior steps as needed. This approach ensures you address existing indoor hotspots while also reducing future ingress from the outside. It’s not sufficient to commit to interior only or exterior only, and no planning wouldn’t cover the areas that actually need treatment.
