"Wow, thank you, thank you, thank you", van der Herchen said in a video recorded after the recovery. When he tried to find out what was making noise, he was shocked to find out it was a boa constrictor.
"From time to time, we would hear noises in the attic", van der Herchen, who owns a bee removal and rescue company, told ABC News.
But his son didn't agree and told his father he thought it might be a snake.
He managed to remove the snake and found shed snakeskin, indicating that it might have been up there for about four years.
The trapper that removed the snake is looking to find a new home for the boa. Eventually, the snake was coaxed out of its hiding place and taken by the snake trapper to a "more suitable home".
"It was actually bunking in the rafter space right above the Florida room chair where my wife sits", he said. His nephew wanted to kill the snake with a spear, but van der Herchen didn't want to go that route, saying it was "animal cruelty".
"The snake got over the PVC pipe and was not moving", van der Herchen said. "It was bigger than I expected".
The man believes the snake was once a pet, a common problem in Florida, and entered his home by a tree branch that was hanging close to his house.
A few days later, van der Herchen caught a glimpse of about a 6-inch portion of the boa and thought to himself, "Wow, that's really big", he said.
Boa constrictors like this one are often kept as pets in Florida.
