Entomology (Study of Bugs)/bug skin in bed

Question
Hello.  I have found shed skin of bugs at the bottom of sheets and on the bedskirt on a bed that no one currently sleeps in.  They are very small and brownish in color.  I also found small black dots around the shed skin.  I looked and found NO live bugs anywhere around the bed, mattress, box spring, etc.  There were not a ton of the shed skins, but enough for me to notice.  I really hope these are not bed bugs.  Is there anything else it could be?  How are they getting food if no one sleeps in the bed?  The sheets have likely not been changed in years.  I found no blood stains.  Could it be possible that there are really no live bugs around?  Thanks so much for your help.  I'm fearing the worst and going crazy!

Answer
When insects shed their skin, they empty their digestive system and that is what caused the dots you see around the cast skins.

As to what insect shed them is another story.  Bedbugs are certainly a possibility, but not a certainty.  Other possibilities include carpet beetle larvae or silverfish.  Only bedbugs can bite people.

If you have pictures of these cast skins, please email them to nlriggs92@yahoo.com.

Expertise

I currently live in San Antonio, TX and have expertise in identifying insects, many types of spiders, and other arthropod critters that infest lawns, ornamentals, structures, trees, pets and livestock. Mites are not a strong point of mine. I'm not a licensed doctor, so I cannot provide medical diagnosis of conditions possibly related to insects or other arthropods. If you've got an interesting photo for me to see, let me know and I'll give you my email so the picture will get to me. If you have hosted an insect photo on a website, please include the link so I can go look at it and provide a faster ID for you. Don't forget...you can now attach pictures to your questions as well!
