YiO Micrantha Insect Repellent

Tiu O Invasive Herb Mosquito Repellent Spray

Story Behind the Product

Across the farmlands of Tiu O (Hong Kong’s western coast), many non‑crop plants grow wild — among them Mikania micrantha, an invasive vine that thrives in the local climate. It spreads rapidly, suffocating native trees and vegetation, and seriously damages local biodiversity.

To tackle this issue sustainably, Hong Kong Distillery partnered with Tiu O farmers to repurpose the plant — extracting its naturally active repellent compounds and turning them into Tiu O Mosquito Repellent Spray.

What Is Mikania micrantha?

Known as mile‑a‑minute weed, Mikania micrantha is one of Hong Kong’s most problematic invasive species. Instead of using harmful chemical herbicides, which could pollute soil, water, and the food chain, our research team pioneered a method to distil the plant into a safe and eco‑friendly hydrosol.

A 2017 study by National Chung Hsing University (Taiwan) confirmed that Mikania micrantha vinegar extracts show effective mosquito‑repellent properties, particularly against small biting midges.

Three years ago, our team began collecting fresh Mikania from Tiu O and developing an optimized extraction process. The resulting scientific eco‑formula combines multiple botanicals for comprehensive protection:

• Lemongrass & Mugwort – Aromatic natural repellents
• Rosemary, Eucalyptus & Lemon Eucalyptus – Deter small insects from clinging to skin and clothing
• Ceylon Cinnamon & Mikania Extract – Repel mosquitoes and midges safely and effectively

Why It Matters

This project turns an environmental problem into a sustainable ESG solution — reducing invasive growth while offering a natural alternative to chemical repellents.
By choosing Tiu O Mosquito Repellent Spray, you protect both your skin and the planet.
