Mouse Extermination Services

in Sonoma, Marin & Napa Counties

We proudly provide mouse extermination in:

Santa Rosa, Petaluma, Rohnert Park, Novato, San Rafael, Napa, St. Helena, Sonoma, Healdsburg, Sebastopol, Fairfax, and all surrounding areas.

Mice might be small, but the damage they cause is huge. From chewing wires to contaminating food and insulation, mice multiply quickly and hide well—which makes them a serious health and safety risk. Our mouse extermination service is designed to eliminate the source, remove the infestation, and prevent future return — with zero poison and zero shortcuts.

Signs You Have Mice in Your Home

Mice are sneaky, but they leave clues. Watch out for:


  • Droppings in drawers, pantries, or baseboards

  • Scratching or scurrying sounds in walls or ceilings

  • Chewed food packaging or wiring

  • Nesting materials like shredded paper or fabric

  • Strong ammonia smell (mouse urine)

  • Unexplained pet behavior or agitation

Why You Should Act Fast

Mice reproduce every 3 weeks. That means a single pair can lead to dozens in just a month. The longer you wait, the worse the infestation gets—and the more costly the damage.

Plus, mice carry diseases like hantavirus and salmonella, making fast removal essential for your family's safety.

Our Mouse Extermination Process

  1. Inspection – We locate where mice are nesting, entering, and traveling.

  2. Targeted Trapping – We place strategic, safe traps in key areas to eliminate the infestation.

  3. Entry Point Sealing – We identify and seal off the routes mice use to get inside.

  4. Sanitation (Optional)– Cleanup and decontamination of droppings and urine.


We never rely on poison or bait boxes that just leave dead rodents hidden in walls.

FAQS

How does your service work? 

We offer a free estimate and service in Sonoma, Napa, North and West Marin Counties. Our expert Rat Detective will find the entry points of rats and mice into your home or structure. We'll catch what’s there and then seal them out. We guarantee our work for 2 years. RES is 100% poison-free and does not use any rodenticides or pesticides.

What do you do if a rat is in between the walls or ceiling soffits? 

We use an attractant to lure rats into our traps which are placed in the active primary traffic areas such as the crawl space and attic. Rats look for a food source and don’t stay in one localized place for long periods. 

What happens when there is activity after the 4 weeks?

RES service will be extended until there is no more activity. Our rat detectives will be executing perimeter checks during each service check. If there is any breach in RES work, or a new entry point is found, it can be addressed.

How can we prevent rats from getting on the roof? 

Rats can jump up to 3 feet. RES recommends having any foliage or branches cut back 4-5 feet to prevent roof access. The use of gutter guards can be helpful too.  

Do you offer a clean up service? 

RES focuses mainly on exclusion work and can clean droppings on hard surfaces. We use a shop vac with a HEPA filter. RES can recommend a company that offers a more extensive crawlspace or attic cleanup.

Do you provide exclusion service for animals other than rats or mice? 

No. RES service for rats and mice only. For any other animals we recommend contacting Sonoma Wildlife Rescue, Wildcare or a local wild animal service provider in your area. 

Do you remove dead rodents from HVAC ducts?

No. We recommend a local HVAC company

How does payment work? 

The initial estimate is provided at no charge. After the estimate and invoice approval, you can pay using cash, check, or credit card payments. We can split the payments in 2. We ask for a minimum of half up front when we begin service and the remainder balance due by the 3rd week of service.
