“I finally understood why the trapping never worked — there were three open entry points that I never would have found without David's inspection. Two were on the roofline and one was at the AC line through the fascia. Sealed. Done. No rats in 20 months.”
Permanent Houston Rodent Exclusion
Rodent Exclusion for Houston Homes
Trapping removes the rodents already inside. Exclusion stops the next ones from entering. Without sealing the entry points, outdoor rodent populations replace trapped animals within weeks — making trapping a recurring expense rather than a solved problem.
- Full exterior inspection to locate every entry point — roofline to foundation
- Exclusion materials that rodents cannot chew through — hardware cloth, concrete, and steel mesh
- Species-appropriate inspection: roof rat entry points differ from Norway rat and mouse entry points
- Written documentation of every sealed location
Why Rodent Exclusion Is the Only Permanent Rodent Solution
Trapping manages the symptom. Exclusion addresses the cause.
- Outdoor rodent populations are continuous — trapping alone removes current animals, exclusion blocks all future ones
- Exclusion materials are permanent — hardware cloth and concrete do not need to be reset or replaced
- Full roofline inspection included — roof rats enter through elevated gaps others miss during ground-level inspections
- All entry point types addressed — pipe penetrations, vents, eave gaps, foundation cracks, and utility chases
- Written exclusion report — every sealed gap documented with location and method
- Exclusion work guaranteed — if a sealed entry point fails and allows re-entry, Resolve returns to address it
Houston Homeowners on Resolve's Rodent Exclusion Work
“David walked me through every entry point he found and explained what material he was using for each one and why. That transparency made it clear we were getting a real solution, not just foam in the obvious gaps.”
“We had a mouse problem that would not stay fixed. Turns out the issue was a gap at the utility conduit where electrical entered the house from the meter. A 2-inch gap that looked small but was enough for mice. Sealed with hardware cloth and steel backing. No return.”
What Rodent Exclusion Covers
Every entry point type, every material appropriate for permanent sealing.
Roofline Gap Sealing
Fascia gaps, eave openings, soffit vent mesh, and roof-to-wall junctions inspected and sealed. Primary roof rat entry zone in Houston construction.
Utility Penetration Sealing
AC line penetrations, electrical conduit entries, plumbing boots, and gas line gaps sealed with steel-mesh-reinforced materials that rodents cannot chew through.
Foundation Gap Closure
Foundation sill plate gaps, pipe penetrations at ground level, and weep hole openings addressed for Norway rat and mouse entry — ground-level inspection separate from roofline.
Vent and Opening Covers
Attic vents, foundation vents, and crawl space openings fitted with hardware cloth mesh sized to exclude the target species. Deteriorated vent screens replaced.
Garage and Door Gap Treatment
Garage door threshold gaps, side door sweep gaps, and wall penetrations in attached garages — a common rodent entry zone that is frequently overlooked in exterior inspections.
Written Exclusion Documentation
Every sealed entry point listed in a written report with location, gap dimensions, and material used. Useful for future reference, insurance documentation, and real estate disclosure.
How Resolve Performs Rodent Exclusion
Comprehensive inspection, population clearance, then permanent sealing.
- 1
Full Exterior Inspection
David inspects the complete exterior — ground level, foundation, roofline, and all utility penetrations — to map every potential rodent entry point before any sealing begins.
- 2
Population Clearance (If Needed)
If active rodents are present, trapping is established first. Exclusion work begins only after the interior population is confirmed eliminated — premature sealing traps animals inside.
- 3
Entry Point Sealing
Each identified entry point sealed with the appropriate material — hardware cloth, concrete patch, metal flashing, or steel-mesh-reinforced expanding foam — matched to the gap type and rodent species.
- 4
Documentation and Follow-Up
Written report provided listing every sealed entry point. Follow-up visit confirms exclusion integrity. If any sealed point fails, Resolve returns to address it.
Exclusion vs Trapping Only: The Long-Term Cost Comparison
Trapping without exclusion becomes a recurring service expense. Exclusion ends it.
| Feature | Exclusion + Trapping | Trapping Only (No Exclusion) |
|---|---|---|
| Prevents new rodents from entering after trapping is complete | ✓ | ✗ |
| Provides a permanent solution rather than recurring maintenance | ✓ | ✗ |
| Total cost lower over 12 months vs repeat trapping visits | ✓ | ✗ |
| Written documentation of sealed entry points | ✓ | ✗ |
| Lower initial cost for the first visit | ✗ | ✓ |
| Eliminates the current interior population | ✓ | ✓ |
| Works without identifying exact entry points | ✗ | ✓ |
Case Study
Cypress Home: Full Exclusion Audit Finds 5 Entry Points Previous Providers Missed
The Problem
A Cypress homeowner had been on a quarterly rodent trapping program for two years — catching 1-3 rodents per quarter and paying for each visit. Activity never stopped completely. Previous providers had sealed two visible foundation gaps but had not inspected the roofline or utility penetrations.
Our Solution
David performed a comprehensive exterior inspection including the roofline from a ladder, all utility penetrations, and the garage interior. Five entry points were identified beyond the two previously sealed foundation gaps: an open plumbing boot on the rear roof, a gap at the AC condensate line, an unsealed electrical conduit entry at the garage, and two deteriorated soffit vent screens. All five were sealed with appropriate materials.
The Outcome
Rodent activity stopped completely after the five additional exclusion points were sealed. The homeowner ended the quarterly trapping program — no new activity in 16 months. Total exclusion cost was recovered within one quarter of eliminated trapping fees.
Rodent Exclusion FAQs
What materials are used for rodent exclusion?
Material selection depends on the gap type. Hardware cloth (galvanized steel mesh) is used for vent openings and large gaps. Steel wool combined with quality expanding foam seals pipe and conduit gaps. Concrete or mortar patch fills masonry and foundation cracks. Metal flashing covers fascia and roofline gaps. Standard foam alone is not sufficient — rodents chew through it.
How do I know if my home has been properly excluded?
A properly excluded home has every gap 6mm or larger sealed with materials rodents cannot penetrate. Resolve provides a written report listing every sealed entry point. As a practical test: if no new rodent activity appears within 4-6 weeks of exclusion completion, the work is likely complete. Continued activity indicates a missed entry point.
Can exclusion be done without trapping first?
No — if active rodents are inside the structure when exclusion is performed, the sealed entry points trap them inside. Dead rodents in walls cause odor and contamination. Population clearance through trapping must be confirmed before exclusion work begins.
How long does rodent exclusion work last?
Exclusion materials — hardware cloth, concrete, and metal — are permanent installations when properly applied. They do not decay, compress, or degrade like foam-only applications. Resolve guarantees the exclusion work: if a sealed entry point fails and allows re-entry, a return visit is provided.
Can I do rodent exclusion myself?
You can seal visible gaps yourself, but DIY exclusion routinely misses the entry points that matter most — roofline gaps require ladder inspection, and utility penetrations require knowing which gap sizes allow which species. Missing one entry point leaves the exclusion incomplete. A professional inspection identifies what is not visible from ground level.
