I have a white powder like substance on all my surfaces and small clumps of this. I also find small hard brown "things" everywhere (look like bacon bits) that will metamorphize right in front of your eyes although most times you will need a magnifier to see this. It will grow black or white strands of hair looking strands that grow. These things BITE and leave,usually, two red stings marks. My bbody is covered with these red marks. It doe's not itch. HELP please?! sa.***@****
