A Colorado house buyer just encountered a nightmarish circumstance.

One day, she realized her dog had “started walking” very slowly while she was unpacking.

“I came over to see what he was looking at, thinking it was like a spider or something, and right here there were two little holes and I saw snakes slither up the wall,” she said, according to the outlet.

Unfortunately, she has discovered ten more snakes since discovering the first one roughly two weeks ago, according to the outlet.

“Everyone claims that they are some kind of garter snake. However, they also mention that no one has ever seen their garter snake so large, she said.

A snake handler, according to Hall, thought the reptiles had been there for at least two years. She claimed to have spent about $1,000 attempting to get rid of the creatures. Although the home’s seller claimed they had never heard of a snake problem there, according to the outlet.
