Because they are extremely annoying, people have come up with strategies to get rid of them here are some options that can suit any type of player.
The friendly way: You can run through the depot or enter in a shop and close the door or use a Stealth Ring for a few seconds also using parcels and trapping them in a corner is a more lasting choice. The unfriendly way: Simple hit them with your fist once or twice, trying not to kill them because of the negative consequences, but enough so that they run away.
The noob way: If you hate them, using a Trap to kill them is a good way to get rid of them. This won't count as a kill from you and you don't have to pay the fee each time you kill one.
