End of Asian Hornet Spring Trapping

The spring trapping period for the Asian hornet is now over. Since early June, queen hornets remain in their nests to lay eggs, and smaller worker hornets take over outside, often escaping traps. It is therefore important to remove, clean, and store your traps for the next season. Leaving them out risks catching other beneficial insects (bees, bumblebees, butterflies, or the European hornet). The City of Spa thanks all participants. Please report your observations (traps installed, hornets caught). This data helps monitor the species' progression, target control actions, and protect biodiversity. Practical information and the reporting form are available at biodiversite.wallonie.be/frelon.
