I just found these extremely small light brown bugs in my daughter's closet and haven't the faintest idea what they are. I want to say that I've seen them in the bathroom near some of the mildew and grime, but why would they also be where it's dry and very clean? Her clothing is washed regularly and never put back once worn. To my best guess, they are probably .5 mm. They almost look as if they are specks of dust, but they move. What are they and how do I get rid of them using something that is both safe for the baby and something around the house like Windex or Anti-bacterial spray?
