Japanese snowbell tree

Asked April 5, 2016, 6:18 PM EDT

My Japanese snowbell tree may be infected by the ambrosia beetle. What treatment can I use to rid the tree of the infestation? Is there a local tree company that will treat the problem? Help!

Look for the frass tubes as they begin to break dormancy.The attached link has a picture of the tooth pick like frass tubes. A residual insecticide can be applied to the bark.Any licensed arborist will help identify the problem and provide the proper diagnoses.http://extension.umd.edu/ipm/landscape-management-nursery-production/ambrosia-beetles-maryland
