Answer-first
The 12-point exterior sealing pass — soffit gaps, gable vent screens, roof vent boots, weep hole screens, garage door bottom seals, dryer vent covers, HVAC line penetrations, plumbing chase gaps, and foundation micro-cracks — is what makes professional pest treatment actually last. Skip this and reintrusion is inevitable.
When this applies to your East Texas home
- You just moved into a new (to you) home and want a baseline seal-up
- You've had chronic pest issues that keep returning after treatment
- You see recurring ant or roach activity in the same 1–2 rooms
- You hear or see rodent activity in the attic (usually October–February in East Texas)
- You have visible gaps around plumbing, HVAC lines or gable vents
- You've had wildlife (raccoons, squirrels) get into the attic
Failure modes we see in the field
- Caulking weep holes: weep holes are drainage vents for brick veneers — caulking causes moisture damage. Use copper mesh or dedicated weep-hole screens instead
- Sealing the garage without treating first: you trap the existing population inside; treat, then seal
- Using spray foam in load-bearing areas: expanding foam can push framing out of alignment; use for gaps under 1/2 inch only
- Ignoring the roof: gable vents, ridge caps and roof vent boots are the top rodent entry route in East Texas fall
What actually works — the proof
Homes that get a full 12-point exclusion pass alongside treatment show reintrusion rates 60–80% lower than treatment-only over 12 months. It's why we make sealing part of every SPOTGuard Defense inspection — the tech logs entry points, seals what's safe to seal on-site (with your permission), and recommends a licensed contractor for structural repairs beyond our scope.

Frequently asked
Does home sealing really help pest control that much?
Yes — it's the single highest-return maintenance step. Studies show combined treatment + exclusion cuts long-term pest activity by 60–80% versus treatment alone. Also lowers HVAC bills 5–15% because the sealing works against air infiltration.
Can I do all the sealing myself?
About 70% of it, yes. Silicone caulk around window frames, weep-hole screens, garage door seals, gable vent screens, dryer vent covers — all homeowner-doable. HVAC penetrations, attic-ceiling penetrations and load-bearing gaps benefit from a professional exclusion specialist.
