    Rat Exclusion

    We equip our technicians to effectively seal gaps in various locations and materials, making it difficult for them to gain entry.

Cascade’s Approach to Addressing Rat Infestations

Cascade has been combating rats in the Greater Seattle, Tacoma, and Puget Sound basin since 1979. We have the experience to detect details of rat problems and locate vulnerabilities to rat encroachment.

Cascade’s rodent control system covers such items as:

  • Rat nest sites—nests may be found in attics, crawlspaces, garages, and other locations.
  • Rat entry points in/on home (or commercial building)—entry points range from gaps or holes in construction, to roof issues (roof rat species), and more.
  • Rat burrows—ground nesting of the Norway rat (a.k.a. “sewer rat”)
  • Structural locations that are vulnerable to future entry by rats—partially damaged vent screening, uneven garage door closure, etc.
  • Food sources for rats
  • Rat-damaged structural components and/or stored items.
  • …and more

The unique rat infestation problem in the greater Seattle/Puget Sound region

The rat infestation in the Seattle / Puget Sound region now amounts to a high-density rat population currently established throughout all our urban and residential neighborhoods.  Rattus norvegicus (the Norway rat, brown rat, wharf rat, or sewer rat) and Rattus rattus (the black rat, ship rat, or roof rat) have displaced other small animals as invasive species until they are firmly entrenched as a serious pest, causing damage and spreading filth.

We have two species of rats found from Tacoma up through Bellevue & Seattle onto Bellingham and the Canadian border, and also from Olympia up through the Olympic peninsula, including Bremerton.  These rats were originally brought via sailing ships along with European settlers and were originally confined to our early sea ports, such as Tacoma, Seattle, Everett and Port Townsend, WA.

That is until our populations grew; along with urban sprawl and rapid increase in suburban neighborhoods in the last part of the 20th century, rats expanded right along with us.

And these rats love the climate, vegetation, and the beaches and marshlands surrounding greater Seattle.

Cascade Pest Control was founded right here in the the Puget Sound area of Washington State in 1979.  We’ve watched the resident rat population spread, drastically increase, and become a formidable presence and threat to us.

We at Cascade have amassed a tremendous amount of experience in:

  • detecting rats,
  • eliminating established rat nests and colonies, and
  • designed effective programs to protect against and even prevent future rat infestations.

The Problem with Rats

Having lived along side rats for millennia, humans have a naturally disgust for rats being as they are associated with bites, rat mites, disease, filth, and destruction of food and property.  The following are some of the specific reasons why rats are such significant pests here in the greater Seattle/Puget Sound region:

  • Rats aren’t natural to the Puget Sound basin, they are an invasive species competing with other, native species.
  • Rats damage many thousands of homes’ attic, crawlspace and other insulation annually. And the cost to replace rat-damaged insulation in such difficult places to reach costs thousands of dollars to remove and replace.
  • Rats damage other structural items of homes, and rats chew or gang on electrical wiring of homes and businesses, often requiring repairs by an electrician and occasionally starting a fire.
  • Rats love to nest in cars, stored RVs and boats. Rats gnaw on auto and other wiring causing expensive repair costs.
  • Rats spread filth and disease, contaminating many surfaces and/or stored food.

Rat Damage is Costly—Cascade’s rat control and prevention is the cure.

The two most common and costly problems caused by rats in our area are damaged insulation and ruined automobile wiring.

Rat-Damaged Insulation

When rats enter an attic or crawlspace, they are attracted to live within our insulation.  Rats both nest in, and create travel tunnels, in and over structural insulation.  This leaves the insulation compressed or shredded to where it has little R-value—it no longer properly insulates your home.  This also leaves your insulation, which is just inches from your living space, filthy and contaminated.  Removing and replacing rat-damaged insulation in these tight spaces is a dirty job, and expensive costing a lot per square foot of area.

Car, Truck, RV and Boat Damaged Caused by Rats

Rats are very attracted to nest in the enclosed spaces found within automobiles, boats, RVs and travel trailers.  Cars and Trucks are hit the worse.  Rats nest in various areas of a car, but most often in the engine compartment and rat-damaged engine wiring is very common and expensive to remedy.  Rats love to chew the insulation on wiring and use it for nesting.  And some “environmentally safe” plastics may even be edible.

How Fast Rats Breed & More…the evolutionary success of rats

  • Rats can climb, jump, swim, and even balance along power wires.
  • Rat breed quickly, with large litters and runaway populations.
  • Rats are geared for survival. Their every move is “life and death” so they are extremely persistent.
  • Rats can gnaw through wood (siding, etc), and many roof materials.
  • Rats are opportunists—able to eat most anything—from garbage, leftover pet foods, spilt bird seed, barbecue drippings inside BBQ units, many and plants, and even dog droppings.

Cascade’s Rat Control

Rat Trapping

Traps are the quickest remedy for active rat problems. Traps are most often set in attics, crawlspaces, and inside of tamper-resistant “Rat Station” placed outside the home or business. While anyone can be lucky with rat trapping it takes experience and know-how to be successful trapping rats. Rats have initial “new object shyness” that can prevent them from approaching traps and utilizing the best attractants is important.

rat bait station

Rat Baits and Bait Stations

Rat control and prevention relies on the use of baits. These rodenticide baits are kept inside tamper-resistant ‘bait stations’ which are strategically placed outside a residence or other structure. The bait stations prevent access to non-target animals such as dogs and cats.

NOTE – Image: rat bait placed inside tamper-resistant rat bait station. Bait is secured so that it is difficult to fall out or for pets and non-target animals to gain access.

Rat Exclusion

Rat or rodent exclusion amounts to “building them out” by placing metal flashing, steel wool, or steel mesh over gaps, holes and other vulnerable spots to prevent easy access to rats. Many aspects of homes and other structures are built with gaps that are never sealed; and even if they are they are often sealed with caulking or other materials that rats can easily chew through.

Your Cascade technician can note areas where rat-exclusion is needed, and often we can provide an estimate for such work. Sometimes a qualified contractor or roofer is required to provide proper rat exclusion solutions.


Rat Abatement

Rat Abatement

Rat abatement refers to quickly reducing numbers of rats on a given property prior to demolition and/or construction and is required by an increasing number of cities in the region. Cascade Pest Control has extensive rat and rodent abatement experience.
