Despite their name, bed bugs can be found under wallpaper, in crevices of furniture, and even behind plug sockets. They’ll stay hidden until feeding time but a check around places like mattress edges or headboard buttons may provide the evidence of the black marks of bed bug droppings. Professional treatment is needed to eradicate any infestation.
An adult bed bug will look like a small brown disc about the size of a match head. However, they can be hard to find, hiding well in crevices, able to go months without coming out to feed. Look first for blood spots on sheets and signs of bites on the beds occupant.
