If it is a sucker, I would get rid of it as soos as I see one.

I totally agree that earworms appear from nowhere--and won't go away! I can awake in the middle of the night and there's a song playing over and over and over in my head. The ones I don't mind too much are hymns; at least I'm 'listening' to something uplifting.

While it is difficult to tell from your picture, it does look like a fungal infection. You can get an anti-fungal from any Big Box store or garden center; just ask someone in the store. The other thing that will help you posting pictures is to use one of the features in Photobucket. When you want to post a picture that you've uploaded to PB, simply click the 3rd item down on the list under the picture. You will see "copied" for a brief moment. Now go back to your post here at C&S and right click your mouse and select "paste". When you "Preview" your message you will see a picture and not link.

"North Safety model 770030" Complete and total overkill for the vast majority of 'old house' work. A high quality disposable with an exhale valve, twin straps, and a formable nose piece is all you need. The vast majority of safety gear and standards are written for occupational exposures of 8 hours a day, 5 days a week. that is why OSHA (Occupation Safety and Health Administration) writes them, and they do NOT alply to individuals in their own homes. There are a few VERY dangerous things you can work with, some that no mask is rated to stop (some auto paints come to mind that require positive pressure breathing gear for anyone using them). Methylene chloride paint stripper is well know to be dangerous to anyone with compromised heart blood circulation (it acts like CO in the body and ties up the bloods ability to carry oxygen). A half face mask is overkill for the vast majority of DIY type jobs unless you have a known sensitivity to something you are using like epoxy amine sensitivity). Just plain old dust and dirt is irritating in high doses for many folks. Your lungs will clear it out in a week or two. If you have no other symptoms, tincture of time is likely the cure.
