termites at work

there are termites everywhere, thank goodness they are silent eaters
I have two places where they leave their trail, there are probably many more but no obvious trails

 This little pile of dirt is beside the gray door and white wall on the gray tile floor

 

this one is in the bathroom corner behind the toilet 

between the chrome shelve  unit and the  red and white wall tile on the gray tile floor

one shut off valve for the whole bathroom
