What area in a home built on a concrete slab is most likely to show evidence of a subterranean termite infestation?

Subterranean termites are known for their unique behavior of tunneling through the soil to directly access the structure of a home. When a house is built on a concrete slab, the areas where utility openings occur present perfect entry points for these pests.

As utilities such as gas, water, and sewer pipes penetrate the concrete slab and extend into the soil, they inadvertently create gaps that can be exploited by termites. These openings allow termites to bypass the concrete barrier and gain access to the wood components of the home, such as framing and flooring, which are above the slab.

Other areas like windows and door frames, basement walls, and attics are less likely to show initial signs of subterranean termite infestations because these termites primarily travel underground. While they may eventually infest wood in these locations, the most immediate evidence of infestation will typically be observed at the entry points where they can access the structure from the soil. Hence, the utility openings are the most probable areas for initial signs of a subterranean termite infestation in homes constructed on concrete slabs.
