Bird control products prevent pigeons, sparrows, and other birds from perching, feeding, and nesting. They are typically used to protect outdoor areas or structures from damage at parks, golf courses, athletic fields, and public buildings. Install these products in locations such as awnings, ledges, balconies, and roofs. Electronic bird repellents discourage birds from flying and nesting near buildings using an audible or visual signal designed to confuse or pose as a threat. Visual and structural bird repellents (gels, animal decoys, tape, spikes, coils, netting) frighten birds from a specific area or make landing or nesting physically difficult. Catch-and-release bird traps temporarily reduce the population of nuisance birds.
