Damage Prevention and Control Methods


  • Close all openings larger than 1 inch (2.5 cm)
  • Place covering at 45o angle on ledges
  • Porcupine wires on ledges or rafters
  • PVC or rubber strips to cover door openings; netting where frequent access is not needed
  • Netting to prevent roosting on building beams or to protect fruit crops 

Cultural Methods and Habitat Modification

  • Reduce availability of food and water at livestock facilities: remove spilled grain and standing water; use bird-proof feeders and storage facilities; feed livestock in open sheds; where appropriate, feed in late afternoon or at night; lower water level in waterers
  • Modify roost sites by closing buildings; exclude from roost areas with netting (for example, under roof beams); modify specific perch sites
  • For tree roosts, prune branches of specific trees or thin trees from groves.


  • Soft sticky materials (polybutenes) discourage roosting on ledges.


  • Nest-box traps, for use during nesting season
  • Decoy traps may be useful around orchards or livestock facilities. Proper care for trap and decoy birds is necessary


  • Helpful as a dispersal or frightening technique. Not effective in reducing overall starling numbers.


  • Frightening devices include recorded distress or alarm calls, various sound-producing devices, chemical frightening agents, lights, and bright objects. Use with fruit crops and starling roosts. Also useful at livestock facilities in warm climates and at facilities located near major roosts.
