What creates the risk here
Richmond Town homes need anti-bird nets when central well-finished homes, older compounds, shaded apartment balconies, refined frontage ledges, and utility windows face tree litter, central-road dust, old-wall fixing limits, crows, mynas, sparrows, and pigeons using shaded old ledges. The issue is repeated mess from different birds around the same ledge, rail, pipe gap, drying side, AC pocket, or utility opening.
