At the end of summer 2026, apiaries in the Alpes-Maritimes face unprecedented pressure from the Asian hornet. These hornets, numerous in front of the hives, capture bees returning from foraging and severely disrupt colony activity, prompting beekeepers to call for a collective response.

The electric harp, a mechanical device made of vertical conductive wires connected to a low-voltage power source, is installed mainly in front of hives. Acting as an invisible barrier, it delivers a lethal electric shock to any hornet that touches two wires simultaneously while trying to attack a bee or approach the hive, without danger to humans or bees.
