Shortly after buying their dream home, Sessions and his wife discovered it was infested with thousands of garter snakes. For the next three months, their growing family lived as if in a horror movie. More than a year after they abandoned the property, the home briefly went back on the market, and they fear it could someday attract another unsuspecting buyer. While setting up a chicken coop, Sessions lifted a piece of sheet metal and was startled to see a pair of snakes slither away. A few days later, he found more and soon started to collect dozens in buckets. At times, there were so many in the yard that the grass seemed to move. If he rapped a stick against the roof overhang, he could hear dozens scatter, their scales sliding against the aluminum. After he removed some panels of siding, dozens of snakes popped out. When he made his way through the crawl space to investigate further, he found snakes everywhere. Sessions said that he has been diagnosed with snake-related post-traumatic stress disorder and that the house should be condemned. "It's not right to continue to sell this home," Sessions said. He and his wife said they still have nightmares and have not recovered financially. In the spring and summer, the reptiles fan out across the wilds of southeastern Idaho to feed and breed. But as the days get shorter and cooler, they return to the den in search of warmth. Since the Sessions moved out, other people have looked at the house. One day, when a real estate agent was showing the property, a farmer who lives down the road stopped by to warn them, Chambers said. "Now, if anybody sees anybody, they kind of will let them know," he said. "Just so that somebody else doesn't get caught in the same trap."
