Bed bugs are small insects that feed on human blood, usually at night while people are sleeping. They hide during the day and come out in the dark to bite exposed skin, often leaving itchy red welts that can disturb sleep and cause stress.

These pests are about the size of an apple seed when fully grown and are experts at hiding in tiny spaces. They often live in beds, furniture, and nearby cracks, making them difficult to detect and eliminate once an infestation begins.
