Hi,
please help me identify this insect. It’s been in my bathroom since quite a few years, and lately in my kitchen too. I live in a block of apartments. It’s about everywhere, and doesn’t fly very well or for a long time. It’s small, about 3-4 mm long/wide.
Thank you very much!

These little moths are all over my house and stick to the walls. They are about a half cm wide and a half cm tall. I just have no idea what they feed on or how to get rid of them. Please let me know! Thanks!
I live in Abu Dhabi… Very hot weather.
