French beekeeper tackles “murder hornet” invasion with homemade trap


Brest, France — French beekeeper Dennis Jaffre, faced with the loss of 35 hornets in a giant invasive Asian wasp, knew he had to act swiftly to save the bees. rice field.

Known as “Giant Hornets,” they have no natural predators and can eat their entire nest in a matter of hours. They thinned bee colonies across Europe.

“I had to find a solution. I was very traumatized by the loss of half of my urticaria,” said Jaffré.

So in 2016 Brittany beekeepers devised a device with a unidirectional mechanism, such as a lobster pot, for catching red-spotted shrimp, which is believed to have arrived in France in 2004 with the shipment of pottery from China. Did.

Originally made of wooden wine crate and metal mesh, it is now 3D printed in plastic. After winning the French Inventor Award in 2018, Jaffré began making traps in bulk. The demand was so high that he stopped taking orders to catch up.

He employs 6 staff and ships to several European countries.

Attracted by the sweet food, wasps invade through a one-way funnel and get stuck inside, but small insects can escape through small holes in the wall.

“If you don’t set up a trap, you’ll see wasps flying in front of the entrance to the beehive. You’ll catch the bees, fly with them, and carve them elsewhere. It’s very hard to see them all day long. It’s difficult, “said Christian Petit, a fellow beekeeper.

Jaffle, who also removes wasp nests in homes and gardens, said destroying the nests would prevent accidents, but would rarely stop the spread of insects.

He said the only way to control the Hornets was to systematically capture them nationwide with the support of local governments.
