A Bit Too Much Time In Crawl Spaces?

Hello. I’m Kurt Treftz a co-founder of Cascade Pest Control. Over the years I and a number of well-qualified technicians have inspected and cared for thousands of homes and businesses in the Pacific Northwest, protecting people and property from pests. Checking out dirty crawl spaces is just one part of that.

Cascade has both C.I.T. and A.C.E. technicians, certified by the Entomological Society of America.


CIT represents that a technician is certified in “Integrated Pest Management,” a disciplined approach that utilizes precise knowledge of pests and a variety of control methods to insure efficacy of control as well as least toxic methods


ACE signifies that a technician has met qualifications for CIT and more, earning the designation of Associate Certified Entomologist.

All of this exemplifies Cascade Pest Control’s commitment to
professional and safe pest control for you.

April Fool’s Day, 1979, Cascade Exterminators Was Born

Started in 1979, Cascade quickly became known for the efficiency, quality, and dependability of its pest control service. Being native to the Pacific Northwest we held a high value for Washington’s abundant natural environment and the welfare of its people and communities.

I (Kurt Treftz) became fascinated by construction practices that either resisted or succumbed to pest infestation and resulting damage. I took a keen interest in entomology, collecting and studying various insects and other arthropods. What’s more, this being the early years of the EPA and the environmental movements, I had a passion for developing least-toxic approaches to pest control.

As a result, Cascade Pest Control pioneered various approaches to solving pest control needs and earned recognition and various awards for safer and more environmentally friendly pest control.

While no one should tolerate pest infestations in their home or business, our intimate encounters with various insect and other pests have given us a measure of respect for them. For instance, carpenter ants and termites are native to a forest ecosystem. However, they can easily damage the structural integrity of your home or business.

On the other hand—although rats are clever, have amazing abilities, and are extremely tenacious—we also know they are invasive species. Seattle was declared “rattiest city” due to our huge rat population. And they annually cause damage to homes, businesses, and autos in the hundreds of thousands of dollars.

Most importantly, we have great people making up our ranks here at Cascade. Each person is dedicated to serving you, our client, as well as understanding your property and its vulnerability to pests. And amongst the Cascade team are second- and even third-generation descendant of the founders as well as some very dedicated long-term personnel. 

So, as Cascade Pest Control continues its rich history of serving residents and businesses of Washington state with the highest standards of practice we invite you to partner with us to protect your property, health, and business reputation.
