Rodent Control & Extermination Services

Rodent Control & Extermination Services

Rats and Mice cause Damage, Filth, and can spread disease.

The Puget Sound region is particularly suited for rodents

  • Rats are well established in all urban/suburban areas
  • Mice are indigenous and abundant in all outlying suburban and rural areas

A Perimeter Defense Service is needed to protect homes from rodent infestation.

Getting Started

Initiate Rodent Perimeter Defense Service

Cascade’s Initial Rodent Service includes

  • Review and assessment of home exterior and reported areas of concern.
  • Traps are set within the entries of any attics and substructure crawlspaces. Rats and mice anywhere in attic or crawlspace will find them.
  • Tamper resistant Bait Stations are placed and anchored at house exterior, usually on each side of home. Traps and/or baits are placed within the stations.
  • Exclusion recommendations are provided according to findings.

Cascade’s Rodent Defense Program

Why is ongoing mouse or rat control important?

  • Rats are extremely well established amongst urban and suburban environments, found in every neighborhood. And mice are in high numbers throughout certain suburban and rural environments.
  • The “population pressure” of rats or mice to move into a structure—with all its heating and insulation for nest material—is very high.
  • Rats and Mice cause damage, filth and spread disease. So, you can’t afford to leave your home unprotected.
  • Rodents are very tenacious and sometimes make full-on assaults on the home. Cascade’s maintenance service* comes with a re-treatment warranty. Extra service free of charge.

Rodent Control When Selling Your Home
An Initial Rodent Service is designed to begin full rodent protection for your home. The maintenance service—as well as any rodent exclusion required—is necessary to fully protect the home and be under warranty. However, if you are selling your home you need to address any immediate rodent issue prior to the sale but you won’t have possession of the home beyond that. In such cases we conduct our Initial Rodent Service plus one trap-check visit. It will then be up to the new property owner to continue service that provides them full protection and a warranty.

Maintaining a protective perimeter defense around a home (or business) is critical to prevent a reinfestation and Cascade Pest Control’s rodent extermination service carries a warranty.

Rodent Exclusion

Locating and sealing, blocking, or otherwise closing up gaps and holes where rats and/or mice can get into your home.  Rodent exclusion includes access points for rats and mice that allow them to enter the attic, wall and ceiling spaces, crawlspace, or even living spaces of your home.

Building rodents out—or “excluding” them—can include:  

  • Repair gaps in crawlspace or attic vents
  • Close gaps where plumbing enters the home from the crawlspace
  • Screen or install flashing at adjoining openings on the roof
  • Seal gaps around garage doors
  • Repair foundation gaps around sewer drain (rats tunnel through the sewer exit gap)
  • Remedy crevices around the crawlspace access door
  • Replace or repair crawl space door that is loose fitting
  • Trimming tree branches nearly touching roof lines (allowing rat access to attics)

Your Cascade technician will report to you what’s pertinent to your home in order to help block rodents.

Special Note: Rodents are very capable of gnawing through many structural building materials so exclusion work alone will not stop them.  However, exclusion is critical and when done in conjunction with the perimeter defense bait stations, the rats or mice assaulting your home won’t get very far because they will succumb to the baits and/or traps we maintain.

Crawlspace and/or Attic Remediation — Removal and replacement of damage

When rodents have damaged or contaminated attic and/or crawlspace insulation we provide recommendations, and at times referrals, to remove and replace insulation that has been shredded, compressed, or contaminated by rat or mouse infestations.  Such rodent-damaged insulation has a substantially reduced R-factor.

Attic and crawlspace remediation is costly being as in either case the workspace is so tight with limited access.  Nonetheless, rectifying rodent damage is important in maintaining the integrity of your home.

Special note about rodent damage and sale of home:  It is now customary for homes to be inspected, and for the inspection to include evidence of rodents, and any damage to insulation from rats and/or mice.  Such damage will have then to be addressed, or it may delay or even thwart a pending sale.
