Answer-first
Pests enter East Texas homes through five main routes: (1) brick weep holes and foundation cracks, (2) garage door bottom seals and side seals, (3) HVAC and plumbing penetrations, (4) roof-vent gaps and gable vents, (5) doors and windows without proper seals. Fix the top three and reintrusion drops by roughly 70% inside 6 months.
When this applies to your East Texas home
- You see the same pests in the same rooms repeatedly (entry route consistent)
- You notice pest activity concentrated near a specific corner or wall
- The house has visible gaps at penetration points (dryer vent, gas line, HVAC lines)
- The garage door has visible daylight along the bottom or sides
- You see mud daubers, wasps or spider webs on soffits or eaves (entry indicators)
Failure modes we see in the field
- Focusing only on doors and windows: these are entry routes for larger pests, but the majority of insect entry is at foundation and roof
- Not knowing what a weep hole is: brick veneer walls have small vertical slots at the base — designed for drainage but wide-open for ants and roaches
- Sealing the garage door without addressing side seals: bottom seal alone leaves 4–8 side inches open
What actually works — the proof
Our exclusion audit maps your home's specific entry routes on a diagram, ranked by likelihood. Treating + sealing the top 3 routes handles ~70% of reintrusion; addressing all 5 handles ~90%. It's a 2–4 hour job for most homes.

Frequently asked
Do all houses have weep holes?
Brick veneer homes do — they're the small vertical slots between bricks at the base of exterior walls. Vinyl, stucco and wood-siding homes don't (they have different drainage systems). If your home is brick, check the base of the walls — you'll see weep holes every 24–32 inches.
