Drywood termites in San Antonio 78254 often enter through attic vents, fascia boards, and window trim on single-story ranch homes built from the 1970s onward. Because they live entirely inside dry wood, treatments focus on direct wood injection with borate or non-repellent termiticides rather than soil barriers. Technicians drill small holes every 12 to 18 inches along infested members, then inject product until refusal, sealing the holes afterward to prevent re-entry.
Edge cases appear in homes near Leon Creek where humidity swings allow colonies to persist in second-story floor joists and built-in cabinetry. We avoid whole-house tenting when possible because many 78254 residents have solar panels and attached garages that complicate fumigation tarps. Instead we combine moisture monitoring with follow-up inspections at 30 and 90 days to confirm colony elimination before any warranty discussion.
Homeowners sometimes mistake drywood pellets for sawdust from carpenter ants or old construction debris. We always confirm with a moisture meter and listening device before drilling, because unnecessary holes in load-bearing beams can create new entry points. In the 78254 area, the most common oversight is skipping the attic inspection where colonies hide above insulation and go unnoticed until frass appears on lower floors.
Technician insight
In San Antonio 78254 the thing that catches most people out with drywood termite treatment is skipping the attic check because they only see pellets on the living-room floor. Older ranch homes here have vaulted ceilings with limited access, so colonies hide in the top plates for years until frass starts dropping through can lights. We always pull back insulation first.
Hidden colony in 78254 attic
Homeowner noticed small pellets on the kitchen counter in a 1978 ranch off Honiley Street. Inspection revealed active galleries in the attic rafters above the master bedroom where insulation had hidden the frass. We drilled and injected the affected members, sealed the holes, and returned at 30 and 90 days to confirm no new activity.
