Keeping pigeons off your building in Williamsburg requires professional deterrent systems installed in the areas where they roost and nest. Bird spikes on ledges, signs, and flat surfaces prevent pigeons from landing without harming them. Bird netting excludes pigeons from courtyards, loading docks, and recessed architectural features. Sealing openings in eaves, soffits, and mechanical areas prevents nesting inside the structure. Reducing food sources by securing dumpsters and eliminating outdoor feeding also discourages pigeon activity. Professional installation ensures deterrent systems are properly placed and durable. Existing droppings and nesting materials should be professionally cleaned up due to the health hazards they present.
