One of the biggest threats to an unwary player are cloaked units as, without any detection, they can ravage entire armies and bases without any retaliation.
My main problem in their use is that players that have ever played a Starcraft game and AI know to build detection of some sort. Because of that I find cloaked units hard to deploy effectively without getting slaughtered. This is especially true when I try to use dark templar since they are melee units.
So my question is, how can I fully utilize cloaked units (specifically ghosts, dark templar, and banshees) in SC2 multiplayer?

Cloak in Starcraft 2 is in general used in two circumstances:
Rushes
Cloaked units is often rushed to early on for a chance to do damage. Dark Templar and Cloaked Banshee rushes are exemplary. The idea of a rush is to get them out as soon as possible, and hit your opponent before have preparations against sufficient mobile detectors.
Sneaky Harassments
The other use for cloaked units is harassments, mainly workerline harassments. When an opponent has multiple bases, it is quite possible that one of his workerlines is not well defended. A cloaked units can easily sneak across the map, and possibly attack without fear of reprisal for a while before a detector is brought in.
In general, Cloaked units should not be gathered en masses, and should strike separate locations to overload opposing detectors.
