TDS (Termite Detection system Detects Termites)

This Is What Sets Me Apart From All The Rest

How It Works


The TERMITE DETECTION SYSTEM consists of a carbon dioxide (CO2) portable detector attached to an air pump, which is combined with a filtered probe. The probe can be used to pierce the sheet rock wall on the inside of a building and the air pump draws out an air sample that is passed to the carbon dioxide detector. A passive reading is taken in the house first and used as a calibration. Any increase above the control reading indicates an active termite infestation. This system detects active termites only.

With the unit in the HIGH SENSITIVITY SETTING slowly run the probe along the baseboard. If the alarm sounds every time the probe passes a certain point this will indicate termites in that area of the wall. This method is 85%-90% accurate, about as accurate as a Termite Dog.

To be 100% certain of an infestation, you then set the TDS unit to the lower SENSITIVITY SETTING, with the small probe attached, and make a needle size hole at the top of the baseboard in the caulk line where the termites were indicated and insert the probe. TDS can pick up a termite infestation within a five foot area.

If the alarm continuously sounds for up to ten seconds once you insert the probe, you have verified the termite infestation with 100% accuracy. (A dab of caulk after testing will make the needle size test hole disappear).
   
This is included with your Home Inspection if signs of Termites appear.
