Exterior treatment along with debris removal along the foundation
The Answer Is:
C
This question includes an explanation.
Explanation:
Earwigs are outdoor pests that enter structures, often hiding in debris near foundations. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Earwigs) recommends exterior treatment (e.g., perimeter spraying) combined with debris removal to eliminate harborage sites. Option A (fogging) is not a standard method for earwigs. Option B (interior baseboard spray) may be used but is less effective without addressing outdoor sources.
