Nutria (Myocastor coypus) on May 8, 2008

Submitter does not have a specimen

Description of specimen

Nutria have been in this wetlands for years.

Also near this wetlands there are an overabundance of squirrels. I do not know what kind they are.


We have been wondering what to do with them for years.

Thank you for submitting the report. Nutria are common in wetlands throughout the Beaverton area. Since you own part of the property, you have three different options.

1. You could privately hire a wildlife control company to trap nutria on your property. A quick online search can identify different companies in the area.

2. Since Clean Water Services has habitat restoration efforts in the vicinity, they may be willing to partner with you on nutria trapping. I know they currently contract nutria trapping on an opportunistic basis. Below is contact information for the person supervising nutria activities at Clean Water Services.

3. You can also contact the Wildlife Services state office (contact information below) and ask them to put you in touch with their local personnel. They may or may not be willing to address your situation.
