We contacted a local firm (ELHRICH) years ago and they did a barrier job, 1
foot increments around the exterior and interior, drilled holes and infused
a chemical termites would not go through...thus the name BARRIER.
15 years later they were back, same company had a new method on controlling
termites.
Termites need to shed to live, a substance is now available to stop the
shedding process and thus killing the termites.
On the outside of a home holes are drilled for tubes to be inserted, inside
of these tubes are pieces of wood termites enjoy eating. This attracts
termites and when activity is detected this wood is removed and a substance
that termites eat but will keep the from shedding is applied, termites eat
this and keep coming back to get more and tell all of their buddies...in
time the entire colony has been destroyed because of their in ability to
shed,,,if termites are killed this will not eliminate a colony, only keep
them from coming back to eat...
I am happy with this and keep it up to date...

Barrier treatments are to keep out and/or kill subterranean termites.
They are typically used, at least in Florida, for new construction.
There has been a lot written about failure of barriers either by
improper mixing of insecticide or because the barrier did not remain intact.

Dry-wood and damp-wood termites live in wood mainly, rather than in the
ground...different bugs, different methods of removing them. Termites
essentially live everywhere, but there are imported varieties, like
Formosan, that are newer and more destructive. Termite control is not
for amateurs.
