Cutaneous larva migrans is caused by:

Ref. Textbook of Microbiology and Immunology BY Parija. Page. 645    The most common cause is A. braziliense, so we prefer that as the answer It is a skin disease in humans, caused by the larvae of various nematode parasites of the  hookworm family (Ancylostomatidae). The most common species causing this disease in the Americas is Ancylostoma braziliense. 
 These parasites live in the intestines of dogs, cats and wild animals and should not be confused with 
other members of the hookworm family for which humans are definitive hosts, namely 
Ancylostoma duodenale and Necator americanus. 
 Colloquially called creeping eruption due to its presentation, the disease is also somewhat 
ambiguously known as "ground itch" or (in some parts of the Southern USA) "sandworms", as the 
larvae like to live in sandy soil. 
 Another vernacular name is plumber's itch.
