If you’ve discovered rats or mice in your attic, crawlspace, walls, or garage, you’ve probably noticed there are dozens of companies claiming to solve the problem. Some are traditional pest control companies. Others specialize in rodent exclusion—the process of permanently sealing a home so rodents cannot return.
Choosing the right company isn’t just about price. It’s about finding a contractor who will identify every entry point, perform durable repairs, clean contaminated areas if needed, and help prevent future infestations.
This guide explains what to look for when comparing companies and highlights several established providers serving Marin County.
What Is Rodent Exclusion?
Rodent exclusion goes beyond trapping or baiting rodents.
A quality exclusion project typically includes:
- Complete exterior inspection
- Identification of all rodent entry points
- Permanent sealing with durable materials
- Trapping existing rodents
- Attic and crawlspace sanitation
- Insulation replacement when necessary
- Follow-up inspections
Many homeowners prefer exclusion because it addresses the cause of the infestation rather than only removing the current rodents.

What Really Matters When Hiring a Rodent Company
1. Do They Find Every Entry Point?
A permanent solution starts with identifying every place rodents can enter. Missing even one opening can allow the infestation to return.
2. Are They Focused on Exclusion?
Many traditional pest companies emphasize recurring bait stations.
Exclusion specialists focus on repairing the building so rodents cannot get back inside.
3. What Materials Do They Use?
Ask whether repairs include:
- Galvanized steel
- Hardware cloth
- Metal flashing
- Concrete repair
- Durable construction materials
Avoid temporary foam-only repairs unless appropriate for the location.
4. Is Cleanup Included?
Rodents leave behind:
- Droppings
- Urine
- Nesting materials
- Contaminated insulation
Professional cleanup may help restore indoor air quality after an infestation.
5. Is There a Written Warranty?
Ask:
- What does the warranty cover?
- How long does it last?
- Is it transferable?
- Are follow-up visits included?

Frequently Asked Questions
Is rodent exclusion better than poison?
Many homeowners prefer exclusion because it addresses how rodents enter the structure. Trapping may still be used during the exclusion process, but sealing entry points is what helps prevent future infestations.
How long does rodent proofing last?
A properly completed exclusion project using durable materials can provide long-lasting protection, though homes should still be inspected periodically.
Is attic insulation always replaced?
Not always. Replacement depends on the extent of contamination and damage.
Should I hire a general pest company or a rodent specialist?
That depends on your needs. If rodents are the primary issue, many homeowners choose companies whose primary focus is rodent exclusion and repairs.
Final Thoughts
There are several reputable companies serving Marin County, each with different strengths. The best choice depends on your home’s condition, the scope of the infestation, and the type of solution you’re seeking.
When comparing estimates, look beyond price. Consider the thoroughness of the inspection, the quality of the proposed repairs, the warranty, and whether the company is focused on providing a lasting solution rather than ongoing treatments.
