This Device Kills Mosquitoes Using the Ultrasonic Power of Cardi B’s Music

Mosquitoes may be tiny, but you should probably be more afraid of them than you are of sharks, bears, snakes, or spiders. The CDC says mosquitoes are responsible for more human deaths than any other creature in the world. That’s because they carry and transmit dangerous diseases like the West Nile virus, malaria, and the Zika virus. Even if you live in a part of the world where these diseases aren’t common, mosquitoes are incredibly irritating. Fortunately, if you know where the mosquitoes are breeding, you can follow Constructed’s Instructables tutorial to build a device that kills mosquitoes using the ultrasonic power of Cardi B’s music.

This device emits ultrasonic soundwaves at a frequency range that ruptures the internal organs of mosquito larvae before they can mature into the adults we all hate. Mosquito larvae grow in still water, so you can simply place this device in whatever pool of water you suspect that they’re breeding in. It avoids the need for nasty chemicals, but you should be aware that the ultrasonic soundwaves will likely kill more than just the mosquito larvae. It isn’t clear exactly which creatures would be affected, but the frequencies could potentially kill fish, frogs, turtles and any other small aquatic or amphibious animals that might inhabit the water where you place the device.

The electronics inside of this mosquito killing device are based on an ultrasonic gun that Constructed had designed previously. The sound is emitted by a piezo transducer, which acts like a small high-pitched speaker. That’s connected to a Bluetooth module, so you can play whatever sound you like. In this case, Cardi B's music is just being used for fun and has to be pitch-adjusted to reach the 15-30 kHz required to pop mosquito organs. The Bluetooth module has a built-in 50W+50W amplifier that can produce the decibels necessary. A small rechargeable LiPo battery provides power. You can use whatever you like for the enclosure as long as it’s watertight, but Constructed used a disposable food container. The piezo transducers are attached to the bottom of the container so that the ultrasonic soundwaves reverberate through the pool of water. If you want to dispatch mosquitoes with ease, we can’t think of a better way to do it than with Cardi B’s music.
