Millions of honeybees escaped into a rural Texas neighborhood after a semitrailer carrying about 400 hives tipped over, officials said.

Emergency officials in Orange County, Texas, shut down roads in the area Sunday morning and warned residents to stay in their homes while crews worked to unload the trailer and salvage as many hives as possible. The county is located east of Houston and borders Louisiana.

No bee stings or serious injuries were immediately reported. Officials haven’t identified the owner of the hives.

Christie Ray, who owns nearby Queen Bee Supply, said volunteers from three or four other beekeeping businesses in the area went to the crash scene Sunday to help.

“They just help each other, that’s what they do,” Ray said. “The beekeeping community is a great community.”
