# Mosquito Hunting Drones LeSonar2 Autonomously Detects and Intercepts Mosquitoes Indoors By Amy Duong | Published 2026-07-31 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/lesonar2 References: [tornyol](https://tornyol.com/)  The LeSonar2 device is an [autonomous micro-drone](https://www.trendhunter.com/trends/featherweight-camera-drone) designed to detect, track and eliminate mosquitoes using ultrasonic sensing rather than [chemical repellents](https://www.trendhunter.com/trends/nitecore-nwl30) or cameras. Weighing 40 grams, the drone employs 32 ultrasonic emitters and 380 MEMS microphones to generate a three-dimensional map of its surroundings through real-time beamforming processed by an Artix-7 FPGA. The system identifies mosquitoes by analyzing their wingbeat frequency before intercepting them mid-flight with its [rotating propellers](https://www.trendhunter.com/trends/vita-bladeless), then automatically returns to its charging station between patrols. Users define a protection zone through the accompanying base station, allowing the drone to patrol continuously without manual operation. By relying on acoustic sensing instead of cameras, the system performs indoor navigation without capturing visual data. Tornyol says the drone operates continuously while remaining silent and chemical-free, making it suitable for residential environments.
