Can anyone help confirm this tiny insect larvae?
Can anyone help identify this insect larvae?


This is a varied carpet beetle larva, which belongs to the species Anthrenus verbasci. 


A. verbasci. larval form, left; matured beetle, right.




  The bed was searched thoroughly and no others were found, but is there likely to be more of them?


It's difficult to say, though, generally, ~40 eggs are produced at a time, and they can remain in the larval stage for 8 months to almost two years.

At any rate, the University of California Agriculture &amp; Natural Resources, and this website, both provide solid information about this insect, and outline measurements that can be taken to protect your home from it.
