I Found a Small worm it looked kind of dark red or something on one of my daighters shirts in her closet?

All the Clothes in her Closet are clean and I also found 2 on one of my sketch pads but its made out of fabric, i read it could be closet moths but how do I get rid of them and find them all without having to spray or have a lot of chemicals because of my daughter. Im renting an older house and i think majority of it is made out of wood and its summer time so keeping bugs out is hard because there seems to be a lot of cracks in the moldings what can I do? Do i need to ask my land lord to call pest control?
