The frames of the harps hold metal wires spaced two centimeters apart that conduct positive and negative charges. When a hornet’s wings contact the wires, they complete a circuit, ******** the bugs as they fly through. Beekeepers deploy the devices in the flight paths of the hornets, all per Reasons to Be Cheerful.

Studies have shown the harps “reduce predation pressure” by up to 89% and that 78% of protected hives survive winter, while only 56% of unprotected hives do. They are also accurate, with 91% of insects ******* by the harps ****** hornets and only 1% domesticated honeybees.

The harps cost about $300, but Costa and entomologist Denis Thiéry have developed a DIY model that cuts the price nearly in half.
