The consensus in the folklore insists that whatever guise the soucouyant assumes, it must leave its shed skin behind, safely hidden, and don the skin once more before the sun rises or it will be burned away. The best way, therefore, to defeat the soucouyant is to find that defenseless skin and rub it with salt or pepper so that the soucouyant can’t put it back on. Another common defense against the creature is to spread rice grains around the home or village; the soucouyant would be compelled to stop and count each grain and again, would be killed by the rising sun.
The National Library and Informational systems Authority of Trinidad and Tobago contain a collection of folklore, including “The Soucouyant ”, where the soucouyant is represented as an old witch woman who is defeated by the village she preys upon.
