What are the signs of a bed bug infestation, and how can I identify a close-up view of a bed bug for proper identification and treatment?

Signs of a bed bug infestation include small red bites on the skin, bloodstains on sheets, and dark spots on mattresses or furniture. To identify a bed bug up close, look for a small, reddish-brown insect about the size of an Apple seed with a flat, oval body. For proper identification and treatment, consult a pest control professional.
