Thank you for the question and the photographs. It is a caterpillar of a moth, most probably in the family Tineidae. They create a bag-like structure around them for protection, it is mainly made from fibres and other debris around our homes. They mostly eat organic debri in our homes, and are associated with bird nests, especially that of pigeons, in or around homes.
The adult moths barely measure around 1 cm, are brown in colour, and are seen around house. This species is harmless in small numbers, but may damage clothes if they come in large numbers. Easy way to keep them away is to keep the bird nest sites clean or by manually removing them - they do not bite.
I hope this helps,
