Bedbugs are an extremely common pest that often infests places where many people come into contact with each other. They are known for roosting in the beds of homes, hotels, motels, hostels, cruise ships, and many other places, though they will often also live in other furniture and the walls. They are small, brown, oval-shaped, and recognizable because of the sweet yet musty odor they produce. Full-grown males are larger than females, and range from 2.5mm to 4.5mm long.
