Flower balconies, often vibrant and compact garden spaces in urban or residential settings, can quickly become hotspots for common pests like aphids, whiteflies, thrips, and fungus gnats. Because these areas are close to living spaces and frequently visited by pollinators, traditional chemical sprays are often undesirable. Biological pest control offers a safe and effective alternative, using natural enemies such as predatory mites, beneficial nematodes, and predatory insects to target pests without harming plants, people, or beneficial insects. Many biocontrol products are easy to apply—such as preventative sachets—making them ideal for home gardeners. This approach not only keeps plants healthy and blooming but also supports a more sustainable and pollinator-friendly balcony ecosystem.
