Furry Logic: The Physics of Animal Life - Matin Durrani, Liz Kalaugher

"The good news regarding Oriental hornets is that they won’t nest in your house. Nor will you find them living in trees or shrubs. Instead, these wasps hang out in intricate underground burrows, which armies of workers hollow out by digging with their mandibles. Carrying the soil in their mouths, the workers head to the nest exit before flying out about 10m (about 30ft) from home. After dumping the soil in mid-air (the naughty litter bugs) they return home for more digging."
