Moths moths everywhere!

Bloody moths and eggs in my flat. I've had to bag up all of my clothes and vacuum everywhere. I can't afford pest control and they just keep coming back each year anyway. Even if I spray the place with a pesticide!. Which is a nightmare with a cat. Because she scratches the doors if shes shut out of a room and she can't go in for 24 hours after I've sprayed. So I'm trying to control the situation without that. I have hoovered everywhere but I still keep finding a few moths. I hate them they make my skin crawl.
