The crab louse, Pthirus pubus (L.), is considered a filthy human parasite, which it is! Crab lice are related to Head Lice, but are more apt to be associated with lack of hygiene. Toilet seats are not the cause.

Body contact with a clean, known partner will prevent “crabs” and other nasty things. These lice are rare now days, but are associated with a certain side of Town. The same MD recommended treatments will work. Prevention is 99% of the answer on this one.

Tongue in cheek – I recently attended an Entomology Meeting in Florida and University of Florida students were selling the tee shirts in the photo.  There were several seminars on crab lice at the meeting!
