Crawl space stain, saw dust, termite, WTF issue

[Bonefreak]

I go into the crawl space to get a sleeping bag for the kids Boy Scout camp…& I notice the plastic bag containing the sleeping bags is wet….& the foam mat under the plastic bag is wet…& it smells like piss!!  I look above and don’t see any stains….cuz we have a beagle who sometimes has accidents in the kitchen in front of the fridge….so I ask my wife to stomp on the floor in front of the fridge …& that’s about 6-8 from where I found the piss….& I see no dripping or stain leading to the piss….but I see a stain and saw dust where she was stomping….but nothing on the floor. Main concern is this saw dust and it could be a sign of termites…..but I don’t see any other evidence of termites anywhere else…cuz I’m pretty familiar with what to look for from a previous incident. 
 

Any ideas out there what this could be?  @Zone50BugNerd u see termites doing this??

But sink drains are no where near that location. Only thing near there is fridge…which does have a water dispenser though. I’ll check that out. Thanks!

Looks like termite tunnels.

Tongue and groove sub floor?  Looks like the purple is a gap in the subfloor. Could be leaking several feet away and the water is riding the joist and coming where there’s a gap in the subfloor.

Sell it and run as fast as you can.

Termites don't leave dust. They use the wood, dirt, and saliva to make termite tubes to travel because they are subterranean. 

Carpenter ants will leave wood dust.

Bee?

Have no additional evidence of bee activity. 
 
it’s strange that the saw dust is at the location of the stain

Carpenter ants like moist wood .

Adam, I’ll DM you my number, I can either come look myself or we can FaceTime an inspection.  I’ll be available Tuesday.  Do not panic about termites!
