SPOKANE, Wash. - The state is setting traps to learn if four species of moths that attack wine grapes have moved into Washington.
Washington is the second-largest grape-growing state in the nation, but vineyards could be damaged if certain species of moths appear.
The state Department of Agriculture says it will place up to 1,000 traps this month to catch moths, mostly in central Washington.
Traps will be placed in most of the 13 major wine grape growing regions. The traps will be checked every two to four weeks during the summer.
Officials say similar surveys the past two years found no sign of the destructive moths.
The European grapevine moth was found for the first time in the U.S. in 2009 in the Napa Valley of California.
