Roach Motel is a theoretical strategy where a group of ground units is surrounded or ambushed in narrow areas by two or more rows of Roaches. By alternating the number of burrowed and unborrowed units regenerating, the surrounded units will have difficulty wearing down their numbers and escaping.
- Note: this will not work on units with teleportation abilities such as Stalkers with Blink upgrades
