Interstate Pest Management
Interstate Pest Management is a family-owned, environmentally-friendly pest control company in the Pacific Northwest. We have been exceeding our customers' expectations since 1963. Our proactive approach to pest control was born out of a commitment to the region we love. We proudly serve the greater Vancouver, Washington and Portland, Oregon area.

We're Northwesterners just like you. And, while we never like pests as roommates, we respect the environment and the key roles each critter plays in our symbiotic sustainability as a whole. So, we do things a little differently. We resolve to remove rodents, insects, bed bugs, and other unwanted visitors naturally before we resort to leveling the playing field with pesticides, following Integrated Pest Management protocols.

We want the best for your family and promise to be upfront with our pricing to ensure that we are providing you with the best pest control service in the Portland & Vancouver metro areas with trained and certified exterminators.

We called to get ants taken care of.
Our call was taken quickly and very professional. The tec showed up on time and listened to what we had to say. Then he got right to it and in a short time was finished and out the door.
Thanks Interstate Pest for the great service.

We are surrounded by field & forest and mice, spiders, earwigs are an issue at different times of the year, I tried everything I knew to eliminate those earwigs. I asked for an inspection & consultation, they walked the property and did an incredible assessment. We signed up for the service, they sprayed around the outside of our house, took down any cobwebs, made sure any access to under the house was covered. We have hummingbird feeders & an infirm older dog that we were worried about (if poisoning), they took care of it ALL without worry for us. Every interaction with them has been courteous

We are faithful customers of Interstate Pest Management for about ten years. We had a carpenter ant infestation in our home. Their technician identified the problem, and treated our house. The ants were gone after the first treatment. We have been on a quarterly maintenance schedule ever since. Anytime we have any concerns, they investigate and take care of everything. We will continue putting our trust in this great company!

Only by virtue of looking up services on the internet of those who manage this type of issue I had randomly chosen a pest control company and hoped for the best. Thats why I am providing this reference today, they deserve this positive acclaim and review I am about to share. PLEASE know I hit the jackpot of perfection- after a few anxious calls to them, in which I was treated so very well and today by my first visit from Interstate Pest Management, I am SOOOOOOO glad I chose them. It is important I share in this review those who answered the phones for my several calls to them have been kind and

Donavan came to my house today, Tuesday, October 24, 3017, to help solve a reaccurring problem with a mice issue in my kitchen. He was very professional and checked every possible place (both inside & out ) that could have a hole where they are coming in !!! He even moved the refrigerator & checked for holes behind it which no technician had ever done. He also found holes in a under counter cupboard that had never been discovered
!!! I called interstate pest today & they told me the first time I had called about this was February 2013 ....over 4 1/2 years ago !!! They would come

We recently had our first visit with the "all seasons package" treating for ants and wasps, Jarrett was great, he was friendly and professional and someone you would want coming to your house. The ants have already disappeared in a couple of days, so far we have felt it is worth the cost to have regular pest control!

My review will not be changing any time soon now that I have received a 'blame' response from the company. While DSHS is a pain in the butt to deal with and slower than slow, I have little to no patience for any company who puts out a customer because DSHS was too slow.

Called and spoke to them about helping me with my possible pest problem. Staff was incredibly professional on the phone - eager to help and pleasant. We have an appointment scheduled and I will further review the service at that time.

As for now, I'm thrilled to know that this group is here to help me keep my home pest-free.

Been having trouble keeping up with wasp nest removal so decided to call in the professionals. Called on Monday and they were able to send out a tech the very next day. Tech showed up right on time and was extremely knowledgeable and able to fully explain all the services they offered. I could have gone with the one time visit for $275 that comes with a 2 month guarantee OR a service plan. I elected to go with the quarterly service plan. $200 for the first visit (which included wasp next removal, preventative ant spraying and sweeping all the eaves around the house) then $98 every 3 mos, when
