Yellow Legged Hornet Trap: our effective, easy, and accessible solution

The Ornetin UV trap is a high-performance trap designed to protect gardens and apiaries from the invasive Asian hornet (Vespa velutina). Its patented UV reflective technology increases visibility by over 80%, making it significantly more attractive to hornets than standard traps.

This enhanced visibility allows the trap to be highly effective throughout the season:

• In spring, it captures founding queens before colonies develop
• In summer and autumn, it targets worker hornets to reduce pressure on beehives

Combined with a selective nozzle system, the trap maximizes capture efficiency and selectivity while helping preserve beneficial insects.

Yes. Ornetin products are designed for selectivity and bee safety. The muzzle protects bees without blocking their flight, and the trap aims to minimize the capture of beneficial insects.

For best results with the Ornetin trap, use a balanced bait that attracts hornets while limiting impact on bees.

A proven and widely used recipe includes:

• Dark beer
• White wine (repels honeybees)
• Fruit syrup or sugar

This mixture is highly attractive to Vespa velutina and works well throughout the trapping season. Refresh the bait every 7 to 10 days to maintain optimal performance. To discover detailed bait recipes, seasonal variations, and expert tips, visit our blog.

The Ornetin system includes color-coded, species- and season-specific nozzles to optimize capture:

• 🔵 Blue nozzle – Designed for founding queens (spring)
• 🟣 Purple nozzle – Designed for worker hornets (summer/autumn)

Additional optional nozzles are available for advanced selectivity:

• 🟡🟠 Yellow/Orange – for Vespa orientalis (mostly in the Spanish regions)
• ⚫ Black – reduces capture of the European hornet (Vespa crabro)

Using the correct nozzle at the right time significantly improves efficiency and selectivity.

Glass jars are sold separately—we encourage you to reuse jars you already have, or add them to your cart if needed.

The Ornetin UV trap is compatible with “Le Parfait” jars and any twist-off jar with a 100 mm diameter (TO100).

Each Ornetin trap includes a printed user guide for quick setup.

Proper placement is key to maximizing trap effectiveness.

Spring (queen trapping):

• Use the 🔵 blue nozzle
• Trap with liquid bait in a vertical position
• Place traps in calm, sheltered areas
• Focus on flowering zones, gardens, and early forage areas
• Start early in the season to stop colony formation

Summer & Autumn (worker trapping):

• Switch to the 🟣 purple nozzle
• Place traps near apiaries and beehives
• Trap with a “solid bait” in a horizontal position

General setup best practices:

• Hang traps at 1 to 1.5 meters in height
• Place traps in a shaded area (avoid direct sunlight)
• Keep traps protected from rain (under a tree, roof edge, or shelter)
• Avoid placing directly at hive entrances
• Check and refresh bait every 7–10 days

Effective trapping depends on two key factors: keeping the bait fresh and maintaining captured hornets alive. Together, these significantly improve trapping efficiency.

Direct exposure to the sun or harsh weather can evaporate the bait and overheat the trap, reducing its effectiveness.

For best results, we recommend placing the trap in a sheltered area, protected from direct sunlight and rain.
