Federal and state agriculture officials say they're conducting another survey to figure out the extent of Virginia's emerald ash borer infestation.
The Virginia Department of Agriculture and Consumer Services said Tuesday they are working with the U.S. Department of Agriculture for the 2012 survey.
Approximately 2,300 traps will be set in central, southern and western Virginia this year.
The 2-foot-tall purple traps are placed in trees during the spring and summer months and then taken down in the fall. The traps' outer walls are smeared with glue. A plastic bag inside contains an odor that attracts the insects.
The beetle has killed tens of millions of trees in the eastern United States and Canada. They feed on the inner bark and disrupt the tree's ability to transport water and nutrients.
