It was their second victory in 11 games.
Ryan Anderson led the Hornets with 22 points. Robin Lopez contributed 21, shooting 8 and 10 from the field and making all five free throws he attempted.
Jason Smith added 12 points and Greivis Vasquez had 11 for the Hornets who shot 52.4% from the field.
''We needed an effort game and we needed to prove to ourselves that when we play like that we can beat a team by a big margin,'' said Anderson, who like Lopez was a young role player on his former team before coming to New Orleans last summer in a trade. ''We needed a win like that at home, too. That was a big win in a lot of ways. It sparks our confidence.''
The Hornets converted 16 Bucks turnovers into 27 points.
''When we defend like that, it gives us a chance to shoot easy buckets and that is how you get close to 50 percent (shooting),'' Hornets coach Monty Williams said. ''You can play against anybody if you play hard and defend. We were fortunate enough to get that tonight.''
