There has been a resurgence of bedbugs worldwide.  While they aren't known to spread diseases, they can cause other problems.  Bedbugs are small, flat,parasitic insects that bite the exposed skin of humans and feed on their blood.  Infestations occur in or around areas where people sleep, and bedbugs hide in the cracks and crevices of beds, box springs, headboards, bed frames and any other objects around a bed.
