A man in Provo, Utah went outside to see what the buzz was about -- and when he found no hives outside, he had to look inside his home, according to KUTV.
"We were just sitting on our couch, turned off the TV and could hear some buzzing in the walls," Tyler Judd, the homeowner, told NBC 2.
With the help of a bee removal specialist, he found that the colony he was hearing lived inside his house, honeycombed into a bedroom wall. And inside the wall were between 40,000 and 60,000 bees.
According to bee specialist Albert Chubak, an exterminator had tried to rid the house of the insects about five years prior, but the bees later reclaimed the wall.
Chubak said that the home was sending swarms to colonize the area and removing insulation from the inside of the house -- and it was time to get rid of them.
