Texas ranks among the most termite-prone states, and Dallas is firmly part of that picture. The soil under North Texas homes is a heavy black clay that expands when wet and shrinks when dry. Over the years that movement opens hairline cracks in slabs and around plumbing, and termites exploit them.
What is eating Dallas homes
Native subterranean termites cause the bulk of structural damage. They nest underground in large colonies, build mud tubes up foundation walls and enter through cracks, expansion joints and plumbing penetrations. Drywood termites occur in smaller numbers, usually in wood furniture and exposed trim. Formosan termites, the more aggressive introduced species, have been documented in parts of Texas, including the Dallas-Fort Worth region, which makes accurate species identification important. Warm weather means colonies can forage for much of the year.
Neighborhoods and housing types
Slab-on-grade houses dominate. In Lakewood, Lake Highlands, Preston Hollow and Far North Dallas, brick veneer, flower beds and sprinklers sit against the slab and conceal the foundation edge. In Oak Cliff, Kessler Park and East Dallas, many older houses are pier-and-beam with crawl spaces, which can be easier to inspect but provide dark, damp areas for termite activity. Homes near White Rock Lake and creek corridors often deal with higher soil moisture and large trees whose roots can open soil gaps next to foundations.
Warning signs
- Flying termites near lights and windows after spring rain.
- Mud tubes along garage walls, piers or the slab edge.
- Sagging or soft floors, especially near bathrooms or exterior walls.
- Stuck doors and windows that did not stick before.
- Small wings piled up on sills.
Inspection and treatment
A licensed inspector will check the garage, attic, crawl space, slab edges, porches, fences and landscape timbers, often with a moisture meter. Treatment for subterranean termites usually involves a liquid barrier applied around the foundation and sometimes drilled through slab edges, or a baiting system with monitoring stations. Providers may advise correcting grading, fixing leaks and removing wood debris. In Texas, termite treatment requires licensed technicians, and companies provide a written treatment record that can be useful when selling a home.
Post-treatment checks are a good idea. In clay-soil areas, shifting ground can disturb the barrier over time.
Prevention
- Keep sprinklers from soaking the slab and repair leaks near the foundation.
- Maintain a gap between soil, mulch and your home's siding or brick.
- Remove stumps, dead roots and old fence posts near the house.
- Stack firewood away from the structure.
- Direct downspouts well away from walls.

Termite questions in Dallas
Do termites go away in the Texas summer heat?
No. They live deep in the soil where temperatures are stable and move toward moisture.
Can I tell if termites are active from the outside?
Not always. Slab homes can hide activity, which is why a trained inspection matters.
When do swarms happen in Dallas?
Often in spring, especially after rains, though swarms occasionally happen in fall.
Is a termite bond worth considering?
Some providers offer ongoing monitoring plans. Ask what is covered and how often inspections occur.
