Ewwwww, Gross!!

Well, my in-laws just walked in about an hour ago. So...my mother-in-law ( have I mentioned she's a good one) and myself are standing in the kitchen talking. Something possesses me to look up at my kitchen fan, which is white. I notice that the white ball pull things on the ends of the chains are COVERED with little brown spots. I was immediately clueless and grossed out at the same time. I climb up on a chair to check it out closer. At this point I notice the same spots all over each blade of the entire fan. I knew what it was.....one of those stupid, little, orange, lady-bug looking beetles. Three weeks ago they were all over the inside of my house. One of them apparently decided to roost up inside the hole in the bottom of the pull on my fan chain and poop everywhere. Not to be gross or anything, but I don't even poop that much and I have Crohn's disease:)! Thankfully I have a mother-in-law who doesn't judge me by my cleaning abilities ( mainly because hers aren't any better than mine. No offense Mountain Mom) It came right off with a Magic Eraser. The question now is this... do I reuse the Magic Eraser? It's only been used once before and has many uses left in it!!!
