Bait stations confine toxic substances to removable units.

Bait stations are effective for controlling pests like roaches or rodents when placed in areas where pests are active, such as near food sources or nesting sites. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 5: Pesticide Application) emphasizes that placement is critical for success, as improper placement reduces pest contact with the bait. Option A (harborage) refers to pest hiding spots, not bait station use. Option B (application as a dab) applies to gel baits, not bait stations.
