A
bed covering device for protecting humans, animals and objects from
crawling pests such as
bed bugs. The device includes a top component for contacting the top surface of
bedding such as a mattress or box spring. The top component includes barrier material suitable for preventing pests from
biting humans or animals resting on the
bedding. The device further includes a fitted side skirt joined to the periphery of the top component and having a slippery, i.e.,
low friction, exterior surface that hinders
bed bugs and similar pests from climbing up the covered
bedding and gaining access to humans, animals, or objects resting atop the bedding. The device may be part of a
system including pillow protectors, headboard and / or footboard protectors for preventing contact by traditional bed coverings with walls or bed structures that may be infested by bed bugs.
