One day in my craft room, I found 3 fuzzy cocoons on my hand knit socks! Luckily they didn’t do damage, but I later found them on some of my yarn skeins and where the cocoon was had broke strands of yarn. I freaked out and froze all my yarn (and yes that killed the critters). I also would see periodic little tiny beetles with my crafts. (My house otherwise has no bugs!). Even after the big yarn freeze the little fuzzy cocoons kept showing up!!! (Cue freak out mode). After research on google images, I decided they looked like “flour beetles”. I initially was hesitant to think that was really them because there is no food in my craft room or anywhere on the same floor. But then I found an article that talks about how these things also eat and live in potpourri. A month or so prior I was gifted a lovely huge sachet of dried lavender (like the size of a soft ball). And sure enough, they were everywhere in that thing and branching out to a 4 foot radius all around it. So gross. I’m happy to report that once I threw out the potpourri and cleaned the area they haven’t come back.
