Which option is described as custom-designed for certain structures in bird control?

• A. Custom-designed ramps or covers
• B. Netting
• C. Bait-type pesticides
• D. High-pressure water

Answer: (A)

Custom-designed ramps or covers illustrate a tailored, structure-specific approach to bird control. Buildings have unique features—vents, eaves, skylights, ledges, and angles—that birds use to roost or gain entry. Designing ramps or protective covers to fit these exact dimensions and contours creates a physical barrier that blocks access or guides birds away without compromising maintenance or safety. This level of customization is why it stands out as the described option. While other methods like netting, pesticides, or high-pressure water can deter birds, they are not inherently described as custom-built features designed to fit a specific structure.
