As summer approaches, and mosquitoes celebrate another season of bloody invasion, you may be wondering: “Why do we have all this AI technology if it can’t do anything about these airborne pests?” There are many reasons to complain about artificial intelligence, but its failure to combat mosquitoes is no longer one of them.
Using machine learning, Inventor Stephen Cheng It has developed a deadly series of prototypes designed to hunt down blood-sucking pests and hit them with lasers. It was Cheng Project history on Xwhere he shares videos of his portable mosquito defense system.
Version 3.0 of the AI mosquito defense system was created during the holiday.
Now equipped with multi-sensor tracking, a redesigned high-speed gimbal, and a Gatling-style launcher for maximum mosquito-killing efficiency.

Cheng He said in his posts He spent four months developing an “artillery gun guided by computer vision + deep learning” as “the ultimate mosquito killer.”
It uses a Canon digital single-lens reflex camera with a high-magnification zoom lens and mosquito-identification software. The search phase resulted in “countless bites all over my body,” he said in a video.
The laser was set to “roast” mosquitoes without harming household items or people, both of which were detected by the program. A wide-angle lens has also been added to improve the system’s ability to recognize humans and flammable materials. The power to the laser is cut off if either of them is in range of the target.
Later versions The weapon added mobility, which led to the cannon being placed on wheels for hunting, including outdoors. Cheng also added a Gatling gun-style design and infrared vision to detect insects even in the dark.
Cheng did not immediately respond to a request for comment.
Other mosquito defenses
Not everyone is willing to build a laser defense system to eliminate flying pests. Some of us buy bug spray and Tools like Thermacells or Hanging bug zapper.
If you have a good goal, then… Salt bug It is a salt-activated granular gun intended to eliminate not only mosquitoes, but also house flies, wasps, carpenter bees and other insects.
Cheng is not the only person using lasers to combat insects. It was a photon array mounted on the base Crowdfunding on Indiegogo last year and is expected to ship this summer. The basic version costs about $500.
