There are four native tree squirrels in Oregon: the Western gray, Douglas, Northern flying, and American red squirrels. There are also invasive nonnative species like the Eastern fox and gray squirrels. They are listed as predatory animals.

While they are fun to watch, squirrels can be a pest when they cause damage to your property. From March to September, squirrels give birth in a nest they created, possibly in your attic or chimney. Squirrels’ teeth or constantly growing, and if they get too big, they are painful. These pests will gnaw on anything hard, including metals, wood, siding, shingles, pipes, ducts, and drywall, to keep them small.

How Do Squirrels Get into My Attic?

Squirrels are outstanding climbers and exceptional jumpers. A squirrel can jump five feet vertically and clear seven feet across. So if you have tree branches within that range to your home, squirrels can gain access to your roof.

Squirrels need an entry point ranging in size between a golf ball to a softball. If the gap isn't big enough, squirrels can gnaw through most housing materials to gain access. 

This squirrel in Portland found a gap along the eaves after gaining access to the roof from nearby trees. 

Squirrel Control in Portland

Most people identify squirrels from the noises they make early in the morning. In this situation, the homeowners actually saw the squirrel make the jump onto their roof. 

​Never try to catch a squirrel. They can carry diseases and will bite or scratch if they are cornered. According to Oregon laws, squirrels cannot be relocated unless it is on the same property. T

We don’t typically have to trap and remove squirrels.Trapping and transporting a squirrel to a facility that will take in the rodent requires a special permit. Hunting permits may be required for certain species during particular seasons.

We install a one way door or valve. The squirrels evict themselves. Once they go through the door, they can't return. You need to make sure all potential squirrel entry points are sealed. Squirrels cna find their way back inside. If babies are in a nest, we remove them by hand and immediately reunite them with the mother outside.

We provided an exhaustive inspection of the property and found the squirrel building a nest in the insultation. We were able to set a squirrel trap and humanely remove it from the home. We sealed the entry point along the eaves and removed the contiminated insulation. 


Great people to work with!
John with CC has helped us twice in the last six years - first with a minor mouse problem, and then in troubleshooting a mystery animal that was raising a ruckus on the roof. In each case he was friendly, professional, and offered excellent guidance on the practical solutions. Highly recommend him, and this company.
Squirrels chewed siding of chimney. CC tech came out to assess situation. Fortunately animals not in attack. CC repair team came out and repaired damage and did a fine job. Very pleased with the business, their work and customer service.
Cannot say enough wonderful things about this company and Joe especially. We recently found a bat in our basement…SCARY! Called and asked for help, Joe came out at 8pm and was able to search the house, capture the bat safely and removed it from our home. His customer service was priceless to me and I highly recommend this company to everyone. Post visit he even sent a team to further assess our property and provide a quote for future needs.
They helped get rid of bats at our house and were friendly and easy to work with, highly recommend
We appreciated the quick response and the careful service by David Gleason. He explained each step of the process. He also returned to reset traps that had been sprung. He was professional and friendly. We highly recommend Critter Control.
Bryan was great. On time, professional, friendly. Most importantly, honest. No lies, no fear tactics, no gimmicks. Assessed the issue and was honest about the lack of work that actually needed to be done/was recommended, knowing that other places had dramatized and given several thousand dollar (4k+) estimates on a job that costs a couple hundred dollars. Can't recommend enough. Will be using for any future issues.
I’ve been using them for several years now. They are great!
Removed bats from our house and sealed up other areas of concern. Very responsive, explained things throughly to us, and did the work in a very timely manner. Much better than their two competitors that we also called. I would highly recommend them.
We have been having issues in our yard, and recently discovered large holes. Called this team, they immediately came out and determined the holes were partially exposed mole tunnels. They took care of the tunnels (as best they could), and trapped and caught a mole for removal. They were responsive, knowledgeable, and thorough. While I hope it is not needed - we would certainly reach out to them again should a need arise!
