We’ve spent years inventing all kinds of things to get rid of mosquitoes. Now we have a promising weapon: a laser that detects them and fries them

Steven Cheng built a homemade prototype that uses a camera, deep-learning algorithms, and a movable laser to detect mosquitoes and kill them in real time.

The article traces the idea back to earlier proposals linked to Nathan Myhrvold, Lowell Wood, and Intellectual Ventures, as well as Bill Gates-connected circles.

A Chinese startup, Photon Matrix Lab, is already selling a similar device through Indiegogo, showing commercial interest in the concept.

But the system’s real-world effectiveness, safety, and practical viability remain uncertain.
