Super Bugs, Tiny Super Bugs
What looks like sawdust from a distance are actually thousands of tiny bugs.
I have no idea what they are, but they are on everything in my little shed behind the house where we have a spare shower, toilet, washing machine, bike, and my goat milking outfit and goat feed. We cleaned it out a week ago and sprayed it down with water, but nothing was different the next morning.
I'm going to spray the whole shed down with bleach next chance I get. Little stinkers.
