The Exterra Termite Interception and Baiting System is a
simplified approach to termite baiting.
The first step in system use is the placement stations around
the outside perimeter of the structure. The interior dimensions of the station
are 2 5/8 inches square by 6 7/8 in deep. The sides of the Station are
perforated to allow termites to enter station when it is placed in the ground.
Before installation, the side walls of the station are fitted with wooden
interceptors that line the interior of the station leaving a vacant cavity in
the middle of the Station. Stations are placed no more than 20 feet apart and
roughly 2 feet from the side of the foundation wall (possibly farther from the
foundation if a liquid termiticide has been applied).
To place the station in the ground, a hole slightly larger than
the station is dug using either an auger or a post hole digger. Care is taken
to place holes close to known or suspected termite activity, as well as the
required maximum 20 foot intervals. We watch out for water lines, utilities
and sprinkler systems when selecting hole placements.
The station is next placed into the hole produced by the auger.
The hole is just large enough to allow the bottom of the station to fit in the
hole.
It is critical in back-filling around stations that soil is
placed against the entire exterior surface of the station. Doing this will
assure that termites have free and complete access to the station..
The finished station installation should look like this.
It may be necessary to make a localized application of a liquid
termiticide to the soil, or to treat any termite infested structural timbers
with an injected termiticide to control any active termites during the initial
treatment phase. Extreme care is taken to avoid
application of any insecticide (termiticide or exterior perimeter insecticide)
on or near installed stations.
Stations are inspected at regular intervals as required by the
label . It is not necessary to disturb the interceptors when inspecting them.
We carefully inspect the interceptors for evidence of mud tubing on the edges,
in the corners, or on the surface of the interceptor.
A critical difference between the Exterra and other termite
baiting systems is found during the baiting process. When activity is noted in
or on the interceptor, it is not necessary to disturb the termites by removing
the interceptor . In fact the continued presence of the interceptors means
termites should have less reason to leave the Station. In the event termites
consume all of the active bait, the cellulose interceptors are still in place
to keep them feeding in the station until the applicator returns to service
the station.
The bait matrix is placed in the cavity formed by the cellulose
interceptors within the center of the station. The termites easily transition
from the cellulose interceptors to the bait matrix. Baited stations should be
inspected within 45 days of bait placement of bait, and bait should be
replenished as necessary.
Within a few months of the initiation of feeding on the bait
matrix, the termites will begin to show the tell-tale signs of the effect of
the chitin synthesis inhibitor. The termites will appear a pasty white or
parchment white color, and we will begin to see a larger proportion of soldier
termites than normal. Full effect generally occurs after the termites have fed
for 6-12 months. At that time there may be no evidence of termites in the
station or interceptors other than numerous soldier head capsules.
When activity has not been observed for a period of 3 months,
it will be necessary to remove the old Station, and replace it with a new
station, or a clean used station equipped with new interceptors. This is also
the time to return to the monitoring phase of the interception and baiting
process.
