During childhood most of us dreaded getting tucked in bed and hearing “good night, sleep tight, don’t let the bed bugs bite.” As kids, we developed some substantiated and unsubstantiated fears of bed bugs, the Boogie man, and vampires under the bed. Excluding mythical creatures, a myriad of critters actually live in our beds and feast on our skin as we lie asleep at night, according to Alltime10s video, “10 Disgusting Things That Live In Your Bed.”

A dirty and dark bedroom is the perfect breeding ground for bed bugs. According to a 2013 Bugs Without Borders Survey, the majority of bed bugs infestations occur in residential settings, such as apartments/condominiums and single-family homes. The blood-sucking critters are the most well-known living invaders of bedrooms, and can even bite up to 500 times a night. They can survive for three months without feeding as they seek shelter in the cracks around the bedroom.

Closely following bed bugs, dust mites can also heavily populate our beds. Beds can contain anywhere from 100,000 to 10 million dust mites that can survive by eating your dead skin cells. They can defecate at least 20 times a day, and their feces can even cause asthma.More life-threatening things, like superbugs, can be found lurking on the pillow cases we place our heads on. In fact, superbug MRSA can actually get into our body through cuts and grazes. Once a person is infected, he will develop blood poisoning before the body shuts down. MRSA is resistant to antibiotics and is actually untreatable in 20 to 50 percent of cases.

Unfortunately, sleeping with our pets will not scare away these gross living things. Pets may actually increase our risk of catching worms, animal diseases, and fleas. This only further attracts bugs and bacteria to feast on our bodies.

Perhaps Mom was on to something when she’d tell us to clean our room.
