A bed system for the inspection and treatment of crawling insects, for example bed bugs, includes a main support panel and at least one movable mattress panel upon the main support panel to define a crevice between the panels for harboring crawling insects for subsequent inspection and treatment. A sleeping mattress is then supported on the mattress panel. The support panel is supported above a supporting surface, for example the floor or a boxspring mattress, by a spacer frame. The support panel further includes a skirt member extending down from the perimeter edge of the support panel by a height of the spacer frame so that the bottom free edge of the skirt member is in close, non-contacting proximity to the supporting surface. Treatment chemicals may optionally be provided in the space below the main support panel which is defined by the spacer frame mounted between the supporting surface and the main support panel.
