TDS II Detects Termites and Bed Bugs

Patent Number: US 6,255,652 B1
Date Issued: July 3, 2001

Termite Detection System Description

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 is used to slowly probe 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. Any increase above the control reading indicates an active termite infestation. This system detects active termites only.

TDS Detects Termites and Bed Bugs

Dry-wood Termites may also be detected by The Termite Detection System; however it does take a little more time when doing an inspection.

The carbon dioxide Termite Detector uses an innovative infra-red absorption sensing cell in the detection process. This cell is much more sensitive than the old technology and gives instant indications of termites.

Although this new technology is more advanced, it is far less expensive than the old. Now all PCO's can afford TDS.

Each unit consists of the re-designed Co2 detector and air pump combination with a filtered probe. Each unit includes “AA” batteries and an impact resistant carrying case.

In these days of environmental concerns, our system is environmentally friendly. It may be used in conjunction with a bait system for added protection or as a standalone system.

The Step by Step Process of Finding Subterranean and Formosan Termites with TDS


1. Press the button to turn the unit on. Unit will beep 3 times and all the LEDs will light.

2. The unit will warm up and self-calibrate for 10 seconds, after which a constant beeping will be heard.

3. Test the unit by exhaling gently into the probe tip. Human breath contains enough CO2 to cause a full-scale alarm in High Sensitivity.

4. Unit turns on in the high sensitivity level (400 ppm) for zeroing in on termite and bed bug infestations. To change to the low sensitivity level for zeroing in on a large termite infestation: Press the button twice (double-click like a computer mouse). The LEDs will scan from right to left and a sweeping sound effect of high to low pitch will be heard. The sensitivity is now set for 4,000 ppm. High sensitivity is used for bed bugs.

5.Double click again to change back to high sensitivity. The LEDs will scan from left to right and a sweeping sound effect of low to high pitch will be heard.

6. To reset the unit to the ambient level of carbon dioxide press and release the button. The LEDs will flash briefly to indicate the reset. All levels of carbon dioxide less than the reset level will be ignored.

7. 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.

8. If Termites are present, the 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.

TDS may also be used to find termites under slabs or any confined space. The HIGH sensitivity setting may be used for checking baseboards, large spaces or to find them in wood boards or beams without penetration.

Locating "Dry-wood" Termites

Since these termites make no tubes, do not come out of the ground and usually have no more than 8,000 in the colony, a more thorough inspection is required.

All termites produce large amounts of Carbon Dioxide and since CO2 is heavier than air it settles to the lowest point in the wall or roof cavity.

With Subterranean and Formosan Termites an inspection of the walls on the ground floor is all that is required. With Dry-wood Termites an inspector must also check additional floors of the building as well as the attic at the lowest points. When TDS signals that Termites are present, with Dry-wood Termites it means they can be anywhere above where the CO2 registered.

XT-2000 in California has been using TDS to locate Dry-wood Termites for eight years now with great success. They use it to test the lowest points in Cathedral ceilings for dry-woods.

Each unit consists of the re-designed Co2 detector and air pump combination with a filtered probe. Each unit includes “AA” batteries and an impact resistant carrying case.
