Despite what you may think, bed bugs do not have a preference for pristine environments versus a filthy place. As long as there exists a steady source of food, namely blood, they can survive anywhere. Any notion that bed bugs are attracted to dirt are simply not true. With that said, the idea of a cluttered place does not make it any easier for these pests to thrive and survive. The best place for bed bugs is warm surroundings with easy access to a blood meal. With these conditions, you might question how fast bed bugs spread.
