Is this done by termite?

[Lei L.]

I opened a wall of an old house and found some wood in terrible shape. There is no sign before ripping off the drywalls. I was told by a contractor there that it's termite. Never dealt with this thing. 

Is this done by termites? What's the best way to treat the termites and kill it forever? 

Thanks

I agree with Jill.  I"ve bought a termite damaged property before.  I'd rather pay a bit for an active pest control at around 100 a quarter that will monitor for termite and treat the other pests as well.  They'd set a barrier around the property with a chemical treatment and I'd suggest removing any standing wood from the yard.  Every pest control place will tell you that you have to have it, it brings them business and covers them on liability. Another thing would be if the property is slab, crawl, or basement?  Slab is a PAIN to treat, but crawl and basement can be checked for entry areas easily enough.

@Jill F.      Thank you all! 

It's basement and I am planning to use the liquid chemeical to establish a barrier. 

Taurus SC is the generic version of Termidor and can be purchased inexpensively. Will ask my GC to dig a trench around to house and pour the liquid after mixing water. Hopefully this will eliminate any potential termite risk in the future no matter if there is still a colony or not.
