How do subterranean termites typically enter buildings?

Subterranean termites primarily enter buildings through cracks in the slabs or foundations because they thrive in soil environments, which provide the moisture and shelter they require. These termites typically build tunnels, known as mud tubes, that help them travel from the ground to the wooden structures above. They can exploit even small openings or imperfections in the foundation or slab to access the wood within a structure. This method is effective for their foraging and nesting habits, as they can maintain contact with the soil, which is essential for their survival.

Open windows are not a common entry point for subterranean termites, as they are ground-dwelling insects. Similarly, accessing a building through the roof is highly unlikely and does not align with their behavior. While termites can sometimes be seen flying, the majority of subterranean termites are not aerial and do not enter homes via doors in a flying capacity. Instead, they utilize their established ground pathways, making cracks in foundations and slabs their preferred means of entry.
