Quarantine

Prevent the spread of Japanese beetle!

A quarantine is in place to restrict the movement of high risk yard debris to currently unaffected locations in the state, in order to keep the beetle adults and larvae contained to Washington county and increase the possibility of eradication.

The Oregon Department of Agriculture is asking all residents, landscapers, and waste managers that work in the yard debris quarantine area to follow the information below in order to comply with the quarantine.
