FYI…this might gross you out!

A woman named Em took to TikTok to offer a warning about how people store their Christmas decorations.

In the video, Em said, “All right, when I got my ornaments out of storage today, I noticed that a bunch had this weird rattle sound.”

She continued, “And as somebody whose interest is constantly being piqued by red flags, I had to know what was inside.”

Em hit a Christmas decoration and broke it…and that’s when a bunch of black bugs spilled out.

And they were ALIVE.

In the video’s caption, she wrote, “If you stored ornaments in a cardboard box, give them a good shake outside before decorating inside.”

This is crazy!

Take a look at the video.
