Deadly Hornet Massacres a Mouse on Video, They're Huge

What appears to be an Asian "murder" hornet took a mouse's life within seconds in a wild struggle that was captured on video ... seemingly proving how deadly these things are.

This video just resurfaced this week and is spreading in light of the news that the deadly version of these insects from across the world has touched down in our own backyard here in North America in the past few months.

A new influx of hornets from Asia -- which have NOT been seen here in the States until recently -- pose a massive risk to our domestic bee population, not to mention humans. With them roaming the wild ... much of the natural order of the animal kingdom is in danger

It's unclear if this is, in fact, a murder hornet -- as we don't know exactly when the clip was shot, or where -- but it certainly seems to reflect what these giant bugs are said to do ... MURDER.

It's crazy to see the mouse fight for its life and try to squirm away -- but it's no use, 'cause the hornet is all over it and stinging/biting away until finally ... the mouse stops. The hornet then flies away and starts coming for the cameraman -- that's when the video cuts out.
