I have small, tiny, black bugs that looks like moving specks of dirt on the edge of my bathtub. This is only been in the past month. What are they and how do I get rid of them? I have been spraying them with RAID when I see them, then I don't see them for nearly a week.
Thank you.

You need to determine what these things are in order to control them. Some invisible tape left over from Christmas will pick them up and they can be attatched to a white notecard to be taken to the county agricultural extension office or a university biology department or even a large exterminating company's local office. Once you know what you have control could be as simple as changing the poutporri up to having your house treated professionally
