Question
I read a post where I person had taken a photo of a pile of white eggs on a wood table.  Like this pile, our dark eggs are laid day after day in the exact same spot even after I clean the floor up!  What can they be?

Answer
Elizabeth,

This sounds like some kind of insect frass or wood borings rather than eggs. In fact this description is sometimes made for drywood termite fecal pellets. Take a look at the map on this page http://www.livingwithbugs.com/drywood_termite.html and tell me if you live within the red area. Post a follow up and we can discuss control options.
