Weird Science - Bugs Trapped in Your LCD
This poor guy has got insects in his LCD that is connected to his MacBook! According to a poster on this forum thread at Apple Support forums, they are called Springtails. Some recommended putting the LCD in a garbage bag and let it out in the sun, some suggested ‘bombing’ the LCD with insecticides, while some believe that they will die out on their own without food. Whichever method you choose, pray that it doesn’t die at a distracting spot and refuse to fall off. You’ll get a “permanent dead pixel”! - from HipTechBlog.com
