Hello sir,

Can you please identify this worm/leech/larvae that keeps showing up in my bathroom?  If you can identify it, would you also have any recommendations for getting rid of it?  Thank you for your time.

Dear Tracie - This appears to be a larva of a beetle in the family Dermestidae, likely in the genus Attagenus (black carpet beetle and allies) - see for an example. These larvae will feed on an extremely wide variety of organic materials, including wool/silk fabrics, furs, feathers, dead insects, etc.  See for a fact sheet on carpet beetles that includes control recommendations.
Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
