Eucalyptus
Eucalyptus trees and shrubs are known for their fresh, menthol-like scent, and mosquitoes hate it. The leaves contain cineole, a natural repellent that disrupts mosquito activity. While large eucalyptus trees need space, dwarf or potted varieties are easier to manage in smaller gardens. They grow best in sunny areas with well-drained soil and benefit from occasional pruning. Crush a few leaves and scatter them around your patio to release more oils. Eucalyptus also makes a great companion plant near entryways or seating zones. With its refreshing scent and insect-repelling power, eucalyptus delivers both atmosphere and protection.
