Damage Prevention and Control Methods
Close all openings larger than 1 inch
Place covering at 45o angle on ledges.
Porcupine wires on ledges or rafters.
Netting to prevent roosting on
building beams or to protect fruit
PVC or rubber strips to cover door
openings; netting where frequent
access is not needed.
Change angle of roosting ledge to 45o
Cultural Methods and Habitat Modification
Reduce availability of food and water
at livestock facilities: remove spilled
grain and standing water; use birdproof
feeders and storage facilities;
feed livestock in open sheds; where
appropriate, feed in late afternoon
or at night; lower water level in
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.
Frightening devices include recorded
distress or alarm calls, various
sound-producing devices, chemical
frightening agents (Avitrol®), 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.
Soft sticky materials (polybutenes)
discourage roosting on ledges.
Starling repellent is currently under
development: methyl anthranilate
(grape flavoring). If successful, it
may be useful for protecting fruit
and as a livestock feed additive.
Starlicide: toxic bait for use around
livestock facilities and, in some
situations, at roost sites.
Toxic perches: can be useful for certain
industrial and other structural roost
situations. (Editor's Note: This method is no longer available)
None are registered.
Nest-box traps, for use during nesting
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.
