Netting is best suited for which applications, given its high cost?

• A. Ledges, window air-conditioning units and roof edges
• B. Ground-level fences
• C. Interior spaces
• D. Water surfaces

Answer: (A)

Netting is a barrier-based exclusion method used to block pests from accessing specific architectural features where they tend to roost or nest. Because it costs more to install and maintain, it’s most sensible to apply it to small, high-value access points on a building—places where birds can establish colonies or cause substantial damage if they get in. Ledges, window air-conditioning units, and roof edges are classic targets: they provide readily accessible perching and nesting spots, and blocking them with netting effectively prevents entry or occupancy without needing ongoing trapping or repellents. These areas are discrete and structurally suitable for anchoring nets, so you gain durable protection where it matters most, while avoiding the impracticality and expense of netting large ground areas, interior spaces, or open water surfaces.
