The larvae is killed inside its cocoons by a process called stiffling. In this process a lot of cocoons are put in a steam oven for 10 to 15 minutes. The cocoons have to be stiffled to kill the larva inside as otherwise, they cut their way out after growing into a moth and spoil the cocoon. A continuous thread of silk cannot be derived from such a cocoon. Stiffling helps us to store the cocoons for a long time.
