DETECTING HIDDEN TERMITES AND BED BUGS WITH TDS-II

 TERMITES

Termites produce more Carbon Dioxide than all other living things combined. They produce this CO2 from digestion of cellulose material. No other insects produce enough CO2 to set the alarm off.

When termites are in a confined space like a wall cavity the CO2 gas accumulates and the TDS-II sensors will detect them.  No wall penetration is required.

To start press and hold the on/off switch to turn the unit on.  It takes 30 seconds to warm up and zero the ambient air.  A steady beep will periodically sound to indicate it is ready to find termites.

When checking a wall, move the probe towards a suspected Termite infestation at a rate of less than 2 inches (50 mm) per second, no more than 4 inches away from the suspected infestation.

 If Termites are present, the alarm sound will increase in rate and pitch and the LEDs will indicate the Termite infestation. False alarms due to the operator’s breathing will only last for 1-2 seconds.

If termites are present the alarm will sound continuously each time the probe is near the infestation.

By inserting the probe into visible termite damage the technician may determine if it is active or old damage.

When termites swarm they look for a light source to exit from. The infestation may be far away from the exit point.

Once a confined space is open to the air the gases dissipate quickly and TDS-II will not be able to alarm on the termites out in the open. It is hard to detect a termite out in the open, because the gas will dissipate rapidly, however If you place some termites in a sealed container for a few minutes and then insert the probe the alarm will sound.

Inside a wall or any confined space the accumulated gas becomes such a large volume that the probe only needs to be near the area. Termite tubes have ports that release the gases. If the probe is inserted into the tube it is possible for the alarm to sound. If the tube is inside a wall cavity the gases will build up in high volume inside the wall cavity. Termites and tubes in the open do not need to be detected. It is the hidden ones that TDS-II locates with extreme accuracy.

 

BED BUGS

To begin testing set the sensor to the bed bug setting. To put the TDS-II unit into this mode of operation, first turn the unit on and allow it to warm up and be ready for detection. Once it is ready put the unit in high sensitivity mode then quickly press the PEAK button four times. The TURBO mode is indicated when the lowest LED green light appears to shimmer. Now the unit is in the highest sensitivity setting. This setting is super sensitive and will easily alert to the small amount of CO2 produced by the bed bugs. Move the probe slowly near the areas being checked for bed bugs. (Do not block the probe tip) If a bed bug is hiding within six inches of the probe the unit will indicate its presence. The audible alarm and lights will be triggered as the air pump draws in an air sample. Once all the air in the bed bugs hiding place is drawn through the sensors the alarm will stop. It will take 5-10 minutes for the bed bug to produce enough gases to set the alarm off again. When the unit indicates a bed bug, further investigation should be performed. We recommend the test method used with Bed Bug Dogs. This method is to mark the spot where the alarm sounded and continue checking other areas. Come back to that marked spot in five to ten minutes and retest. If the alarm sounds again in the same spot this strongly indicates that bed bugs are present.

If bed bugs are out in the open air their gases will dissipate too rapidly for the powerful sensors of the TDS-II to detect them. If it is in the open it can be seen and does not need detecting. A bed bug must be hiding where its emissions can build up for about 5-10 minutes to be detected.

 

TDS-II is also a great sales tool for potential customers looking for modern highly accurate methods of solving their termite and bed bug problems.
