Modern tricks are toilet papering yards and buildings, powder-bombing and egging cars and people and homes, using soap to write on windows, "forking" yards, setting off consumer fireworks, and smashing pumpkins and jack-o'-lanterns.

In the Midwestern U.S. and Eastern U.S., this event is known as Cabbage Night, in which children resort to all of the prior stunts, as well as using moldy food such as cabbages and eggs to throw at homes. Also, bags of feces are set on porches and lit on fire, so that when the pranksters knock on the door, the recipient stamps out the bag and covers their shoe in undesired feces. Less vandalous though, is the ever-popular "ding-dong-ditch": in this 'game', people ring doorbells, then run and hide somewhere nearby. Areas known to use this term include Northern New Jersey, New York, Connecticut, Rhode Island, and Vermont.
