How-to : Empty and reset the trap

Safety reminders

• Always wear thick gloves to avoid being stung, even after the hornets have died.
• Use protective eyewear if necessary
• Work away from busy areas (terrace, children, animals)

Getting rid of Asian hornets

Kill the hornets

• Freezing : Place the entire trap (jar + head) in the freezer for 30–40 minutes until all the hornets are dead
• Water immersion : submerge the trap in a bucket of cold water until the hornets die.

Using the freezing method is often cleaner and faster.

What should be done with dead hornets?

• Empty the trap at the back of the garden, away from frequented areas (avoid the compost).
• If you prefer, place them in a sealed bag before disposing of them in the household waste.

Tip : Keeping a few dead hornets to put back in the reset trap can increase its appeal thanks to pheromones. Leaving some previously captured hornets can help attract new individuals, as pheromones act as an attraction signal.

Cleaning and maintenance

Cleaning the jar

• Rinse quickly with clean water to remove visible debris
• Avoid rubbing intensely: leaving a slight trace of pheromones can enhance attraction during reactivation

Trap head maintenance

• Check that the trap head is not damaged or cracked.
• Gently clean the exhaust and intake holes with a soft-bristled brush to remove any residue.
