A mom from Colorado was in the process of moving into her new house when she found that her dream home was overrun with “shockingly big” snakes.

Amber Hall said that when she closed on the four-bedroom, two-bathroom home in Centennial, she had no idea that the property doubled as a snake den.

Hall said that it was one her dogs that made the skin-crawling discovery in the garage while she was unpacking her belongings during the move.

“There were two little holes right here and I saw snakes slither up the wall…”

The woman described the unwelcome house guests nesting in the walls as “shockingly big.”

“Everybody’s saying they’re some form of garter snake. But they’re also giving the caveat that nobody’s ever seen their garter snake that big.”

Garter snakes are non-venomous but can strike and bite humans, sometimes causing an allergic reaction.

Hall said that she had spent her entire adult life saving up to buy her first home, and now she and her family cannot enjoy it — and are even afraid to use the bathroom for fear that a snake would emerge from the toilet.

The unlucky homeowner said that in less than two weeks, she has seen close to a dozen snakes in her home.

The woman has hired a snake wrangler to humanely remove the critters — a move that has already set her back more than $1,000.

She said the pest control specialist told her that some of the snakes had been living on the property — possibly in a den hidden under the house — for at least two years, based on their massive size.

She doubts that she is the first person to see the snakes at the house.

A representative of the real estate company Hall used to purchase the house told the news outlet that she would have been told about the snakes if anyone had seen them earlier.
