The bed bug used to be a pest of the past, but has made a resurgence over the last few years. Hotels and apartment complexes are vulnerable to these insects due to the sheer number of people coming in and out of them. The bed bug is about the size of a small tick and feeds on human blood. If there is an infestation, bed bugs will seek shelter during the day in cracks and crevices and come out at night to feed. They can be found around mattress trim, boxsprings, bed coverings, bed frames, wall hangings, baseboards, behind loose wallpaper, light switches, etc. Small spots of blood can sometimes be found on the bed sheets. Proper treatment is key in controlling a bed bug infestation, as they can quickly spread to other areas of the building and become a much larger problem.
