The honeybees had been making the enclosed cavity their home since 1996, hardly bothering the homeowners. The cabin was rarely used, but when the owners needed to occupy it while building another home nearby, they decided the beehive wasn't safe for their two children.
A few bees had found their way inside the house, and the hive was just outside a window of a children's bedroom.
They didn't want to kill the honeybees, a species in decline that does yeoman's work pollinating flowers and crops.
So they called Bachman, owner of Deseret Hive Supply, a hobbyist store that can't keep up with demand for honeybees.
Bachman used a vacuum cleaner to suck the bees into a cage.
"It doesn't hurt them," he said.
The job took six hours. At $100 an hour, the bill came to $600.
"The bees were expensive," said Paul Bertagnolli, the cabin owner. But he was satisfied with the job.
Utah calls itself the Beehive State, a symbol of industriousness. Whether this was Utah's largest beehive is unknown, but Bachman said it would rank high.
"It's the biggest one I've ever seen," he said. "I've never seen one that big."
He used smoke to pacify the bees, but Bachman said honeybees are gentle creatures unlike predatory yellow jackets or hornets, which attack, rip apart and eat honeybees, he said.
"They just want to collect nectar and come back to the hive," he said. "Most people never get stung by honeybees it's a yellow jacket."
Bachman reassembled the hive in a yard of his North Ogden home, while saving some of the honeycomb for candles and lotions at his store. He left other honeycombs for the cabin owners to chew on.
"We caught the queen and were able to keep her," Bachman said. "The hive is in my backyard right now and is doing well."
