I called someone and he quoted me $1400. So, I ordered the chemical on line for $78 plus shipping. It came from Florida. I was told it was unavailable to me in Tn. because I did not have a proper license. My brother used to work for Orkin and he told me how & where to drill the holes in my foundation. I rigged a pump w/nozzle on a 20 gal trash can and in just one day, VOILA. Never saw another sign of a termite.
The warning that came with the chemical stood my hair on end, so I made damn sure I wore the correct protective clothing, eye wear, etc. If the labeling is accurate, I am pretty sure the stuff will kill you along with the termite.
