In 2010, the U.S. Fish and Wildlife Service (USFWS) proposed listing nine large constrictor snakes as injurious under the Lacey Act, which would significantly reduce the trade of these species as pets. However, in January 2012, only four of the nine species were listed. USFWS is still considering the remaining five species of snakes for listing and is soliciting public comments on the matter.
Large constrictor snakes have become established in parts of Florida and are consuming native wildlife, including endangered and threatened species. Scientists with the U.S. Geological Survey concluded that all nine species of these large constrictor snakes present a “high” or “medium” risk of becoming invasive.
