What is Rodent Exclusion?

Rodent exclusion is a proactive and effective method of preventing rodents from gaining access to your crawl space and. Rather than simply dealing with rodent infestations after they occur, rodent exclusion focuses on identifying and sealing off potential entry points to deny rodents access in the first place.

Common Invaders: Rodents and Wildlife in Puget Sound Crawl Spaces and Attics

Norway Rat (Rattus norvegicus)

With its stout body and scaly tail, the Norway rat is a familiar sight in urban and suburban areas, often found near human habitation.

Roof Rat (Rattus rattus)

Agile climbers, roof rats are skilled at accessing high places such as attics and rooftops, where they may seek shelter and food.

House Mouse (Mus musculus)

Small and adaptable, house mice are notorious for their ability to squeeze through tiny openings, making them a common household pest.

Deer Mouse (Peromyscus maniculatus)

Native to the region, deer mice are often found in wooded areas and grasslands, where they play a vital role in the ecosystem.

Raccoon (Procyon lotor)

Known for their distinctive facial markings and dexterous front paws, raccoons are skilled climbers and opportunistic feeders.

Opossum (Didelphis virginiana)

The only marsupial native to North America, opossums are adaptable creatures known for their unique behaviors, including playing dead when threatened.

While these rodents and pests are a natural part of the Puget Sound ecosystem, they can become problematic when they invade our homes and properties. Proper prevention and management strategies, such as rodent exclusion and habitat modification, can help mitigate the risks associated with these creatures and promote harmonious coexistence with nature.

The Process

Start on a journey to protect your home from sneaky rodents with the careful process of rodent exclusion. It starts with looking all over your crawl space and attic for places where rodents could get in.

Our skilled technicians pay close attention to detail as they investigate and search for any spots where rodents might try to sneak in. From tiny gaps in the walls to cracks in the foundation, we don’t miss a thing. We look even deeper, checking for broken screens, burrows, and any holes around pipes and utility lines that could be secret passages for these unwanted guests.

Building upon the insights gathered during our thorough investigation of potential entry points, we progress to the next phase: diligently sealing off these access points. Employing an array of specialized materials such as robust metal mesh, durable wire wool, sturdy concrete, reliable adhesives, and versatile expanding foam, we craft a formidable barrier against rodent intrusion. Additionally, we take the extra step of installing secure crawl space access doors, ensuring comprehensive protection to keep rodents out.

Additional measures homeowners can take to fend off rodent invasions

Maintain Cleanliness

Keep your home and property clean and free of clutter to reduce hiding spots and potential food sources for rodents. Regularly clean up spills, crumbs, and food debris, and store food items in airtight containers made of glass or metal to deter rodents.

Trim back vegetation, shrubs, and trees near your home to eliminate potential pathways for rodents to access your roof or attic. Overhanging branches can provide rodents with easy access to your home and should be pruned regularly to minimize this risk.

Use secure, rodent-proof containers to store trash and compost outdoors, and avoid leaving food waste exposed for extended periods. Keep lids tightly closed and clean containers regularly to prevent odors that may attract rodents.

Bird feeders can attract rodents looking for an easy meal. Consider removing them or placing them away from your home to deter rodent activity.

Store pet food, birdseed, and other potential rodent attractants in tightly sealed containers to prevent easy access.

Rob and crew from NW Crawl Space did full remediation for our crawl space and attic, after finding evidence of rodents (mice) in both areas. Removed old crawl space insulation & vapor barrier, replaced heat-ducts that were damaged, & vacuumed out attic insulation and debris. Sealed openings in both areas to prevent rodents from returning. Traps set, with rodent control plan. Highly recommended!

Northwest Crawl Space Services has been honest, professional, easy to work with, and has done excellent work on my home. I first approached the company looking for someone to reinsulate and clean out my mud room crawlspace-- it is an addition to the house and is open-air. Lior came by and noted that because NWCSS specializes in fiberglass insulation, they wouldn't be able to work on this part of my house, because it would require spray foam insulation to truly be rat and weather proofed. I really appreciated this up front honesty-- two previous contractors had given me bids to reinsulate with fiberglass, never mentioning the need for spray foam, and never saying that they wouldn't be able to do a proper job. I would have paid money to some other company for a shoddy, inappropriate "solution" if Lior had not filled me in. Lior even recommended some other companies to call that specialize in spray foam! After this helpful and informative experience, I knew right away when I discovered signs of rats in my main basement crawlspace that I wanted NWCSS to be the ones to work on the problem. Lior came by to check it out and did a very thorough inspection. His manner with clients is excellent-- I never felt like my questions were being dismissed. We set a date for a crew to come by to replace rat-infested insulation, remove the improperly installed vapor barrier, clean out debris, and reinstall vapor barrier to industry standards. The crew, Patrick and Chandler, were friendly, polite, and happy to answer questions. Savannah in the office has also been very friendly and quick to answer my questions regarding logistics and payment. Overall, my experience was excellent and I will re-hire NWCSS when it comes time to reinsulate and clean out my attic crawlspace.

Matan gave us a fair estimate for the crawl space re-insulation and screening, and the work was done promptly. I was pleasantly surprised when the final bill came in about 15% UNDER the estimate. It’s nice to deal with a company which has the integrity to pass those savings on.

Northwest Crawl Space is a trustful company to work with. They helped me install the French drain, replace the insulation and vapor barrier. Matan and his stuff did a great job. They will carefully protect your home when performing the job, clean the waste after the work is done, and come back to inspect if the work is good.

We had Northwest crawlspace come out to inspect our crawlspace and they identify a lot of standing water as well as rodent activity in the insulation. As a result, we needed a full clean out of our crawlspace and new insulation, vapor barrier, drain and sump pump. The crew was professional, friendly and fast. The work was extremely well done, we recently had them come out to check everything and the technician confirmed it was one of the best installs he had seen. I would highly recommend this company to anyone.

I had Northwest Crawl Space Services remove all my rodent infested insulation and vapor barrier. They cleaned & disinfected my crawl and installed all new insulation and a sealed vapor barrier. The workers were very diligent and and skilled in their methods. I was given a quote up front and feel that I received a quality job that was worth every penny. I am beyond pleased with the company and would highly recommend them to everyone.

Frequently asked questions

Is the exclusion done from inside or outside the crawl space/attic?

The exclusion process can be conducted from both inside and outside the crawl space/attic. However, it’s often found to be more effective when done from inside. This approach allows technicians to have a better view and access to potential entry points, such as gaps, cracks, and openings, which may not be visible or accessible from outside. By performing exclusion from inside, technicians can thoroughly inspect and seal off these entry points, ensuring a more comprehensive and lasting solution to prevent rodent intrusion.

Signs of a rodent problem may include droppings, gnaw marks on surfaces, chewed wires or insulation, strange noises in walls or ceilings, and sightings of rodents or their nests.

While some rodent exclusion tasks can be performed by homeowners, such as sealing small gaps or cracks, professional help is often recommended for more extensive or challenging projects to ensure thoroughness and effectiveness.

Materials commonly used for rodent exclusion include metal mesh, wire wool, expanding foam, caulk, adhesives, and concrete.

Rodent exclusion should be performed as needed, depending on factors such as the age and condition of the property, changes in the environment, and any signs of rodent activity. Regular inspections and maintenance can help identify and address potential issues before they escalate into larger problems.
