We experimentally demonstrated that tonal acoustic signals with a carrier frequency of 140–200 Hz had a repellent effect on male mosquitoes (Culicidae).

Which frequency is best for mosquito repellent?

Crickets have frequencies between 0.2 kHz and50 kHz. So they have the potential to control mosquito pests. Existing studies state that mosquito pests can be expelled with a frequency of 18–48 kHz. But this still cannot eliminate mosquito larvae, which require a wave of 85 kHz.

Does high frequency repel mosquito?

Besides, there is no scientific evidence to prove that mosquitoes are repelled by high-frequency sounds. ... Plug-on ultrasonic devices called “Electronic mosquito repellents" or EMRs which, like the apps, claim to emit high-pitched sound, have been around for years.
