Winter sanctuary
Turns out the property was a winter snake sanctuary, likely a snake den or hibernaculum where snakes gather in large numbers to hibernate for the winter, said Lauri Hanauska-Brown, a biologist with the Idaho Department of Fish and Game.
In the spring and summer the snakes fan out across the wilds of eastern Idaho, but as the days get shorter and cooler, the snakes return to the resting place - in this case, the Hepworth's new home - where they ball up for heat.
The snakes are likely a terrestrial garter snake, Hanauska-Brown said. Reptiles are a protected species meaning the Hepworths cannot bait them or kill them, she said.
The couple has not contacted Fish and Game to move the garters, Hanauska-Brown said. The department would attempt to move the snakes, but it could be difficult because if they move them too far they would die and if they move them close by the snakes would likely return to hibernate, she said.
'That sounds kind of Indiana Jonesish'
"They are used to going there and kind of balling up," Hanauska-Brown told The Associated Press. "That sounds kind of Indiana Jonesish. But this is a natural thing." Yup, Ayrlin your right! I guess reptiles like snakes had to evolve different ways of making it through winter.
