I’ve been noticing these little black bugs in my bedroom, I had all my drawers out and they were everywhere! I had to hoover them all up. Does anyone know what causes them? I must admit I’m terrible for chucking stuff away, I’ve kept all my sons school work, letters to me they wrote, which had me in tears because I haven’t looked at them in so long, I can’t bear to throw them away, but not sure if these bugs are attracted to paper or something.
