Bed bugs are generally not considered dangerous because they are not known to transmit diseases to humans. However, their bites can cause various health and mental issues including itching, allergic reactions (which can be severe in rare cases), skin infections from scratching, anxiety, and loss of sleep. The bites typically cause red, itchy spots that may appear in lines or clusters. People with allergic sensitivities might experience more serious skin reactions or, very rarely, anaphylaxis. Infestations can also lead to significant mental health stress and economic consequences due to the difficulty of eradication and related costs.
