Bird access often comes from a specific opening or sheltered ledge. Identifying the route first makes it easier to compare a suitable deterrent with a broad, unnecessary installation.
Find the entry and landing points
Check balconies, window ledges, ducts and service openings. Note where birds enter, perch or nest, and avoid disturbing active nests without checking applicable local guidance.
Compare suitable approaches
Netting can cover an opening, while spikes may be considered for compatible ledges. The shape, surface and maintenance access determine whether either option is appropriate.
Plan for cleaning and inspection
Ask how the area will be accessed after installation and what routine checks are needed. Keep the building rules and humane treatment in mind.
