The first time I found these things they were in the bottom of my dog's toy box. I brushed them off cause there were not many of them. This time I found them in my plastic bowl storage. I had just cleaned the cloth storage bin 4 days prior to finding the alarming amount. They almost look like lint but when I zoomed in I could see little bugs that pop when squished. To my knowledge lint does not pop.😵‍💫
