Thanks to an anesthetic in their saliva and an extremely sharp, straw-like mouth they use for piercing your skin and sucking your blood, you won't wake up during a bed bug feeding.
Bed bugs do not live in or eat dirt, nor do they eat food waste or crumbs. All they need to feel at home in your place is a human host they can get a blood meal from. Additionally, bed bugs do not really care whether their host is a clean or dirty person.
Bed bugs pierce human skin with elongated beaks through which they extract blood. Bed bug bites are not initially painful and can go unnoticed for hours or days. This allows bed bugs to withdraw human blood for up to 10 minutes with each feeding. Bed bug bites occur most commonly on exposed skin, such as the upper body, neck, arms and shoulders.
Bed bugs are not known to spread disease. Bed bugs can be an annoyance because their presence may cause itching and loss of sleep. Sometimes the itching can lead to excessive scratching that can sometimes increase the chance of a secondary skin infection. What health risks do bed bugs pose?

Bedbugs do hide in the seams and crevices of your mattress. Since these nocturnal insects feed on your blood, it is to their advantage to live close to the place where you spend the night. But that doesn't mean bedbugs only live in mattresses.
