(There are lots of mosquito species and they react with different frequency ranges.)
This sound consists of crispy bonfire sound and 20kHz ultrasound which human ain’t able to hear. Do not use earphones(headphones). Adjust the audio volume level where you feel comfortable but no more than 50%. If you are with children, we recommend setting the volume under 30% because they may hear the ultrasound.
