Bousillage is a mixture of clay and straw, animal hair, or Spanish moss used in many early Louisiana structures as insulation. The use of bousillage occurs in 18th-century vernacular architecture in Francophone communities throughout France, Canada, the Caribbean, and the Mississippi Valley.

This 2007 video, featuring Master Bousillage Artist Dale Pierrottie, Louis Michot of the band Lost Bayou Ramblers and his wife, Ashlee Michot, Effie Michot, and more, captures the creation and installation of a bousillage wall in the Prairie des Femmes community in St. Landry Parish, Louisiana. The wall was part of a house built by Louis Michot over the course of 2004 to 2009.
