Why would anyone stick their arm into a box containing 5,000 mosquitos?

All in the name of technology! A new app promises to keep mosquitos away by emitting a high-frequency noise that the bugs apparently hate. The "Today" show co-hosts wanted to give it a try on Thursday, so NBC News correspondent Kerry Sanders took on the challenge.

"You guys make me give blood on these stories, literally," he said.

Within minutes, it was clear that the app wasn't working. The reaction from the "Today" hosts was one of immediate regret.

"Get your hand out of there!"

"Take your hand out, Kerry, PLEASE!"

"Get your hand out of the hole!"

Matt Lauer's face sums it up:

The result?
