Quick Answer
Rodent exclusion costs $300-$1,500 for a complete home sealing. The average cost is $600-$900 for a standard single-family home. DIY exclusion costs $50-$200 in materials. Professional exclusion includes inspection, sealing all gaps larger than 1/4 inch, installing door sweeps, and sealing utility penetrations. Most companies offer a 1-2 year warranty on exclusion work.
Rodent Exclusion Cost Guide
Rodent exclusion is the process of sealing your home to prevent mice and rats from entering. It is the most effective long-term solution for rodent problems. Unlike trapping, which only addresses the current infestation, exclusion prevents future infestations. The cost varies based on the size of your home, the construction type, and the number of potential entry points.

The Exclusion Process
Professional rodent exclusion follows a systematic approach:
- Step 1: Thorough inspection of the entire exterior (foundation, roofline, vents, utility penetrations)
- Step 2: Identification of all gaps larger than 1/4 inch (mice) or 1/2 inch (rats)
- Step 3: Sealing gaps with appropriate materials (copper mesh, steel wool, caulk, spray foam, hardware cloth)
- Step 4: Installing door sweeps and weatherstripping
- Step 5: Covering vents with heavy-gauge mesh
- Step 6: Follow-up inspection to ensure no gaps were missed
- Step 7: Warranty period with free re-inspection if needed
Materials Used in Exclusion
| Material | Best For | Cost | Durability | DIY-Friendly |
|---|---|---|---|---|
| Copper Mesh | Small gaps, pipe penetrations | $10-$20/roll | Very High | Yes |
| Steel Wool | Small gaps, temporary | $5-$10/bag | Low (rusts) | Yes |
| Expanding Foam | Large gaps, insulation | $8-$15/can | Medium | Yes |
| Hardware Cloth (1/4 inch) | Vents, large openings | $15-$30/roll | Very High | Yes |
| Metal Flashing | Roof edges, soffits | $20-$50/sheet | Very High | No (requires tools) |
| Caulk (exterior grade) | Cracks, small gaps | $5-$10/tube | Medium-High | Yes |
| Door Sweeps | Bottom of doors | $10-$30 each | High | Yes |
DIY Rodent Exclusion
DIY exclusion is feasible for many homeowners. The basic materials cost $50-$200, and the work can be done over a weekend. However, thoroughness is critical — missing even a single 1/4 inch gap can allow mice to re-enter. Professional exclusion is recommended for larger homes, homes with complex foundations, or if you have already attempted DIY and failed.
Factors Affecting Exclusion Cost
- Home size — larger homes have more potential entry points
- Age of home — older homes typically have more gaps and cracks
- Foundation type — slab foundations have different entry points than crawlspace or basement
- Siding material — vinyl siding has more gaps than brick or stone
- Landscaping — trees and shrubs near the house provide rodent access to the roof
- Previous damage — existing rodent damage may need repair before exclusion
Exclusion vs Trapping: Cost Comparison
Exclusion is a one-time cost that provides long-term protection. Trapping is a recurring cost that only addresses the current infestation. Over a 5-year period, exclusion ($500-$1,500) is significantly cheaper than repeated trapping ($200-$800 per year for ongoing infestations).
FAQ: Rodent Exclusion Cost
How long does exclusion last?
Professional exclusion with quality materials typically lasts 3-5 years before requiring maintenance. Some materials, like copper mesh and hardware cloth, last 10+ years.

Does exclusion work for all rodents?
Yes, the same exclusion techniques work for mice, rats, and squirrels. The key difference is the gap size — mice can enter through 1/4 inch gaps, while rats need 1/2 inch gaps.
