Giant Yellow Jacket Nest.

Shelly and Tony Roberts’ got some bug problem: yellow jackets, to be exact:

Rising up out of the water, it looks like another tree stump from a distance. But a closer look is enough to take your attention, and maybe your breath.

Hundreds of thousands of yellow jackets swarm in and around their nest on Shelley and Tony Roberts’ pond. They can’t believe it got so big so quick.

"I reckon it was a couple of months ago," said Shelley. "All it was was a little stump and we noticed what looked like mushrooms growing up."

It looks to be about six feet tall and three feet wide. No one’s gotten close enough to measure.
