GERMANTOWN, Wis. (AP) _ A tractor trailer carrying 4 million to 5 million bees overturned, blocking a road for more than eight hours as authorities tried to gather up riled bees.

``We're used to tactical situations of dealing with people, but the possible injury of multiple stings from bees is something strange to us,'' Capt. Craig Evans said today.

No one was injured in the accident, but a few people got stung helping out in the cleanup in the rural village 20 miles northwest of Milwaukee.

``That's kind of a part of the territory, though, when you work with bees,'' said Becky Werner, who owns the farm with her husband and got stung herself. ``If you got tipped over in the middle of the night, you'd be angry too.''

The truck was bringing about 570 hives from a local honey farm to Florida, when a wheel caught a ditch and the load shifted and rolled the truck Monday night, authorities said.

Officers who came on the scene kept their distance until a cleanup crew, including volunteer beekeepers in protective clothing, was in place, Evans said.

Temperatures close to freezing overnight killed some bees, and kept the rest from flying off, Werner said. The bees were crawling, because ``at night and in the cold weather, they don't fly,'' she said.

She said she had no idea how many bees were killed.
