Locating Asian hornet nests is finally possible. Several teams have used INTUITE products to track hornets back to their nests – and destroy them. Locnest is now available to the general public.

a radio tag to follow hornets

LOCNEST is a tag that weighs roughly the same as a bee—about 125 mg—which is glued to the back of a hornet to track it using a handheld antenna connected to a phone. The tag emits a signal for over 3 hours, and the signal can be received from more than 3 km away. The cost is around €60 per tag (which is reusable) and under €300 for the antenna kit.

Technical details

A community to share best practices

Technically, the tool is well-developed: it works! And it can still be improved. What remains to be done is to develop a decisive and rapid protocol regardless of the environment. This is where collaboration and sharing will make the difference.

The forum

how it works ?

Capture a hornet. Attach the tag made in Toulouse. Locate the signal using directional antennas. It will all be much clearer in a video :


We have worked a lot since the video

On the day of the video (late July 2023), we did four tests; the video doesn’t show everything, but at the time, the tag only had a range of 250 meters. We thought that would be enough… but we lost the signal three times. Today, the range is more like 3000 meters. .


Latest updates

Locnest is continuously improving with the goal of offering a low-cost solution, both in terms of equipment and time spent.

The hornets take off well

90% of the hornets take off well, but we lose the signal too often: the beacons do not have enough range.
