A zipper cover?
Bed bugs are horrible, horrible creatures. They love soft fabrics and will bite you relentlessly. You’ll have to hire an exterminator to eradicate these pesky creatures, which is a pretty costly and time-consuming endeavor. And worst of all, you can find bed bugs everywhere, from your home to your office and even hotels!
One hotel guest wasn’t quite sure what they were looking at when they snapped this photo. Apparently, the zipper’s cover is will stop bed bugs from getting into the pillowcase through the zipper. We’re not sure how useful this is since these pests can find other means to penetrate pillowcases.
