Are these termite fecal pellets?
 

My wife found these little piles of black sandy things 5 days ago, 2 days ago and now today.
Are these termite pellets and is the tiny hole near the top made by termites?

Thanks very much!

Time to call the exterminator. It's not a DIY thing to fix and no just spraying with some spot spray bug killer will not work.

YEP. Black or salt-n-pepper . . . it is clearly the sign of termites. Get all over this.
