Prevent Pigeons from Perching:
1. Physical Barrier: Install a physical barrier such as netting, spikes, or wires on the balcony to prevent pigeons from landing and perching.
2. Slope or Inclined Surface: Make sure the balcony has a slope or inclined surface to discourage pigeons from roosting.
Remove Nesting Material:
1. Regular Inspection: Regularly inspect the balcony for any nesting materials like twigs, leaves, or feathers. Immediately remove any found materials.
Scare Tactics:
1. Reflective Objects: Hang reflective objects such as CDs, foil sheets, or wind spinners to scare away pigeons.
2. Owl Decoy: Place a realistic owl decoy or kite in a prominent position to deter pigeons.
3. Electronic Deterrents: Use ultrasonic devices or sound deterrents that emit high-pitched noises that are unpleasant for pigeons.
4. Natural Predators: If possible, encourage the presence of natural predators like hawks or falcons in your area.
Repellents:
1. Pepper Spray or Cayenne: Spray a mixture of pepper spray or cayenne pepper on the balcony to deter pigeons.
2. Ammonia: Place saucers filled with ammonia in areas where pigeons tend to gather. The strong smell can deter them.
Habitat Modification:
1. Cover Food Sources: Make sure there are no accessible food sources like bird feeders nearby that could attract pigeons.
2. Eliminate Water Sources: Check for any dripping faucets or water features on the balcony. Water can attract pigeons for drinking and bathing.
Falconry:
1. Professional Falconers: If the problem persists, consider hiring professional falconers who use trained falcons to scare pigeons away.
Consult Local Bylaws:
1. Regulation Information: Before implementing any pigeon control methods, check with your local bylaws and regulations to ensure you're not violating any rules.
Remember, it's important to be persistent in your efforts to deter pigeons. Combining several methods mentioned above can increase your chances of success in keeping your balcony free from pigeon feces and nests.
