Really, it was the best theory I had heard! And there's actually some substance to it!!
Cos seriously unless you have a maid/girlfriend/mother, that sheet ain't getting changed for a while!
So everyday, instead of torturing yourself with effort and moving the snoring cat from your pillow cos, you know it was up all night annoying you, just pull all the sheets back to the feet end of your bed.
Bed bugs and mites love dark, moist, gloomy environments with nothing but tasty morsels of dead skin cells and sweat to feed on.
Beat them off with some laziness and don't make your bed! The air and light will dry them out and they will die a slow meaningless death, despising your new found knowledge!
Genocide on a whole new level! And fresher sheets for longer!!! Winning!!!!!'
