There is no scientific evidence, that ultrasound-emitting devices and smartphone apps repel mosquitoes. We used a cage with 200 female Yellow Fever mosquitoes (Aedes aegypti) to demonstrate this very clearly: Patrick, our fearless mosquito breeding specialist, introduces his hand while holding a smartphone with an activated anti-mosquito app into the cage and gets countless mosquito bites within only a few seconds.

For comparison, he spread an efficient mosquito repellent (30% DEET) on his arm, and introduces the arm into the cage. Some mosquitoes land for a moment, but they fly away without biting.

If I could rate videos from 1 to 10, this gets a full 10. Straight on the point, no clickbait and nothing else. Plus points for his bravery.

[bobbodaskank]

I appreciate how short, sweet, and to the point this was.

He's not the hero we deserve, he is the hero we need

I grew up in Africa and I have lost three friends to malaria so I would like to appreciate you and your bravery for at least saving me and anyone out there who would have downloaded an ultrasound app thinking it'll repel mosquitos. thank you

Arm: *Enters cage for 0.001 sec*

Mosquitoes: This is some serious gourmet shit.

Those bites are horrible. Thank you for risking your comfort to help others.

[AdamPradanaWPutra]

Could we appreciate the fact that he willingly sacrifice his hand for science? XD

[nakymawlot]

To some people this content could be 20 minutes long video

"Mosquitoes having the feast of their life"

Respect to this guy for sacrificing his hand to research to keep away mosquitoes

"Dinner's ready bois"
"Yo he even put on some music this time"
"Hell yea I vibe to this"

[ishaanbhatt]

Fun fact : They attract mosquitoes instead of repelling

[Titusknapp]

This guy is so tough. I would not be able to handle that much mosquito bites.

[josephjoe]

A 48 second video is so refreshing and all that this needed. Other youtubers would extend a video like this to 10 minutes or more and waste your time.

At his funeral*

Carefully, he's a hero

[wenomechainsanna]

The app works it’s just that the mosquito’s are deaf.

[EXRazeBurn]

I wanted to give this man a hug after I saw that arm.

You didn't have to do this, you poor thing.

But we salute your sacrifice.

He: second time placing hand
mosquitos: come back tomorrow our stomach is full
