Inspection Verification
To effectively suppress and presumably eliminate termite colonies, Exterra stations must be
inspected and baited. Although no method of inspection verification is absolutely foolproof, the
inspection verification methods used with Exteris can help keep inspectors honest, particularly if
the method is backed up with random field checks of stations by supervisory personnel.
There are two inspection verification methods available for use with Exteris. One is a barcode
swapping arrangement. The second one uses a handheld data collection device referred to as
the ExScanner that takes the place of barcode swapping.
Barcode Swapping
Barcode swapping eliminates the need for a field barcode scanner or rather makes the use of a
field barcode scanner optional. Instead of scanning the barcode in the station, the barcode in the
station is removed and replaced with a new one. This is a fairly efficient inspection verification
system if you have a relatively small number of sites. This process is illustrated with the following
example:
Barcode Label A, with a unique number on it, is left in Station 123 during station installation. The
number on Barcode Label A is recorded on a Workorder as having been placed in Station 123.
The Workorder is turned in at the office where the fact Barcode Label A has been placed in
station 123 is recorded in the Host Computer.
During the next inspection of Station 123, Barcode Label A is removed. Barcode Label B (with
another unique number on it) is left in Station 123. Label A is turned in at the office and recorded
by Exteris as having been removed from the station. Exteris automatically checks to make sure
Barcode Label A "belongs to" Station 123. If Barcode Label A does match with Station 123, this
is accepted as proof that the station inspection occurred.
During subsequent inspections of Station 123, Barcode Label B will be removed and replaced
with Barcode Label C and so forth. This substitution process continues on a regular basis for as
long as the station remains in place and inspections of the station are being made. Random field
checks of a few stations can ensure that technicians are placing barcodes into the stations
properly. During these field inspections, it is important to make sure a barcode label is present in
the station AND that the barcode matches the station correctly.
It is arguable that it is harder to defeat the barcode swapping verification method backed up with
random supervisory field checks of stations than a scheme that involves assigning a permanent
barcode number to a station and scanning it with a field barcode scanning apparatus (see
ExScanner below). Exteris' barcode swapping inspection verification system combined with
supervisory double checks makes Exterra's inspection verification almost foolproof.
