Plant them near entryways or under eaves where birds typically gather.
2. Rosemary Bushes
Strong aromatic oils released from rosemary leaves create an environment birds find unpleasant for nesting. The intense fragrance that humans enjoy cooking with actually serves as a powerful avian repellent.

3. Bougainvillea
Thorny stems hidden beneath vibrant papery bracts make bougainvillea an unwelcome landing spot for nesting birds. The sharp thorns deter even persistent species from attempting to settle in.
California’s warm climate allows these colorful vines to flourish year-round, creating spectacular displays in magenta, orange, and white. They climb walls and trellises beautifully while providing excellent protection.
Regular pruning keeps them manageable and increases their defensive thorny growth.
4. Lavender

California gardeners plant lavender in mass groupings along foundations and near windows for maximum effect. The purple flower spikes attract beneficial pollinators while discouraging unwanted bird activity.
Drought-tolerant varieties thrive with little water once established in California soil.
5. Yucca Plants

Japanese barberry varieties offer burgundy or golden foliage that adds colorful contrast to landscapes. These tough plants tolerate various soil types and require minimal watering.
Prune annually to maintain their compact, impenetrable shape for maximum bird-deterring effectiveness.

Varieties range from low ground covers to tall upright forms, all adapted to the state’s diverse climates. Their blue-green needles stay attractive through every season with virtually no maintenance required.
Spacing them closely together increases their effectiveness as bird barriers.
10. Eucalyptus Trees
Aromatic oils in eucalyptus leaves produce a strong menthol-like scent that birds find overwhelming for nesting sites. California’s landscape wouldn’t be complete without these iconic Australian natives that serve double duty as bird deterrents.
Fast-growing species provide quick screening and privacy while keeping feathered visitors at bay. Their distinctive bark and silver-blue foliage create stunning visual appeal.
Be mindful of their eventual size when planting near structures and power lines.
11. Spanish Bayonet

Plant multiple specimens together for an impenetrable defensive perimeter around your property.
12. Russian Sage
