Question: do bald faced hornets live in the ground

Answer: No, Dolichovespula maculata is found in forested areas and in vegetation in urban areas. Nests are generally located in trees and bushes but they can occasionally be found under rock overhangs or the sides of buildings. Vertical distribution of nests has been recorded from heights of 1.1 to 20 m (3 ft 7 in to 65 ft 7 in) above ground level.
