In the hills of Brittany, France, Denis Jaffré’s life as a beekeeper was nearly undone when invasive Asian hornets destroyed half of his hives in 2017. What began as panic and loss became the spark for innovation. Rather than surrendering, Denis turned curiosity and grief into determination, experimenting tirelessly in his garage to create a solution that would protect bees without harming other insects. After many failed attempts, he developed a simple yet precise trap: a baited chamber designed so hornets could enter but beneficial pollinators could not. The result was an effective, ethical tool that restored balance to his hives and offered hope to beekeepers facing the same threat across Europe.

Denis’s invention soon gained national recognition, earning a medal at France’s prestigious Lépine Competition and transforming a personal experiment into an environmental breakthrough. In 2021, he founded Jabeprode, growing from a one-man effort into a small workshop employing local craftspeople who hand-assemble the traps with care. Today, his design is used in 18 European countries, with growing interest from abroad, praised for controlling a destructive invasive species without damaging biodiversity. Yet Denis’s vision extends beyond production. He advocates for responsible, non-toxic hornet control and works to educate communities on sustainable solutions. Through crowdfunding and continued research, he hopes to expand his work and empower individuals—beekeepers, farmers, and homeowners alike—to play a role in protecting pollinators. His story shows that meaningful environmental change doesn’t always begin in institutions; sometimes, it starts in an attic, driven by persistence, respect for nature, and the belief that every small action can make a difference.
