Noxious Weed Control
Vineyard Vertebrate Management
Caution
Managing vertebrates can be challenging due to legal restrictions on trapping and use of chemicals. The information provided below is to help the reader understand general biology and what typical control options are. However, if an information source was produced outside of WA, some of their recommendations may not be legal within the state. Contact your local Extension or WSDA wildlife expert to make sure management activities are legal before attempting them.
