Over the past few days, we reported on the Asian murder hornets that have made their way to the United States. The hornets are enormous, and their stings can prove to be deadly to humans.

Now, a video has surfaced showing a YouTube star allowing himself to be stung by one of these murder hornets, and what happens to him is sure to make you even more terrified of the giant insects.

Insider reported that Coyote Peterson is known online as the “king of sting” because he travels the world experiencing different types of stings for his YouTube show. In one episode, he chose to get stung by the Japanese giant hornet, a subspecies of the Asian giant hornet.

“I haven’t been this nervous since the tarantula hawk,” a shaking Peterson said as he held the gigantic hornet between tweezers. He proceeded to lower the insect onto his arm and allow it to sting him, and the pain was immediate after that.

“Oh man, wave of dizziness really quick,” Peterson yelled, adding that the stinger had lodged in his arm. “Searing pain. Absolute searing pain. Did you not see how slow the sting was?”

“When the stinger went into my arm, I had this wave — this wave came over me, and I got super dizzy,” he added when asked to describe the sting. “Almost didn’t feel what was happening. And then the pain was immediately searing.”

Peterson’s arm can be seen swelling up in a dramatic way, and twenty minutes later, he said he was still in agonizing pain.

“No relief yet,” he said. “It’s just a matter of harnessing the pain, controlling the level of pain, and rolling around on the ground and screaming at this point.”

The murder hornets kill fifty people per year in Japan, and they have wreaked havoc on beehives all over Asia for years. They have recently been spotted in the U.S. for the first time in Washington state, after it is believed that they came to America on a ship from China. Experts have warned that they will likely make their way to the east coast in the coming months, and that they are in the states to stay.
