They seems to show up semi-randomly, every few minutes, but there is a teleport sound when they do. Here's a little trick I figured out during the Easter 2014 Event, when I kept looking for Bunnies: Enter the move menu (the four way arrow icon) and tap on the icons to hide the roads and rivers, buildings, and decorations, but leave the eye on the characters icon open, now you can see all the characters clearly (including the bunnies, um, I mean Aliens in this case) even though the buildings. It's like having x-ray vision! Once you find where the Aliens are you will need to edit the Move mode to squish them (tap the back/left arrow in the upper left corner). When you first come back after being gone awhile it should be easy to find plenty of Aliens, but I use this trick to clean up and catch the few I may have missed, especially if they are behind tall or big buildings or Decorations.

The other thing some people do to make finding characters easier is to only have one road. A few of my neighbors do this, having just one main road, some short, some the full width if town, but the Aliens tend to walk on the sidewalks so this restricts them. I prefer to have a nicely laid out Springfield, but I do limit my roads so that it's easier to search them all. In my Krustyland I created a single large oval path and put all my rides and games near it. It still looks nice but it makes finding all my park visitors every 4 hours much easier so I can collect their tickets. I used to have a huge paved area in my Krustyland, but it made checking everything take much longer.
