Trench and treat the outside foundation. The first basic
step.
Trench and treat inside the crawl space foundation wall. This
is necessary if your house has a crawl space or a basement with
a dirt floor.
Treat the soil under a crawl space. If space is limited, we'll
usually have to drill small holes in the outside concrete wall
surrounding the crawl space.
Treat beneath the flower boxes or other parts of the structure
that protrude out from the main structure.
The soil in bath traps must be treated and access panels may
have to be cut.
Treat behind the brick veneer.
Treat the spaces around the chimney.
Treat hollow blocks.
Treat cracks, expansion joints and voids under the basement
floor or slab.
Treat near the ducts in the slab.
Treat the areas where the pipes and utility lines penetrate
the slab or basement floor.
Treat through holes drilled around the perimeter of the slab.
