Longmeadow Monitors Emerald Ash Borer Outbreak


People may notice purple boxes hanging from ash trees in different parts of Longmeadow.  The boxes are sticky traps designed to catch Emerald Ash Borer beetles (EAB) that attack only ash trees.

The EAB is a small green beetle that entered North America in wooden packing materials from Asia.  The EAB attacks only ash trees. The beetle lays its eggs on ash trees and its larvae attack the living tissue of ash trees and the trees die within several years.  The EAB was first discovered in the area around Detroit, Michigan and Windsor, Ontario in 2002, Since 2002 the beetles have been responsible for the death of hundreds of millions of ash trees in the Midwest and Canada and their range is increasing throughout North America.

Last fall EAB beetles were discovered in Longmeadow in a section of the conservation area near the Connecticut River.  The State of Massachusetts is treating the infestation with biological controls.  For more information about the EAB, go to the following website:

To determine if EAB beetles are spreading to other parts of Longmeadow, the Tree Warden has placed the six purple sticky traps throughout town to monitor the possible spread of the beetles.  If it is found that the EAB beetles have spread into town trees, procedures to control the infestation will be initiated.

For the traps to be effective, residents are asked not to disturb the traps.
