Look for Ash Tree Flecking

This time of year is easier to find EAB infested trees. February and March are good times to look for woodpecker damage to ash trees (known as “flecking”), and potentially find new EAB infestations or expansions of known infestations.

If residents have any desire to save ash trees on their property, they must act now.  Residents which have an ash tree smaller than twelve inches in diameter can successfully treat their own tree with products bought at home and garden centers.  Products such as Ortho Bug B Gone Year Long Tree and Shrub Insect Control or Bayer Advanced Tree and Shrub Protection are examples of insecticides labeled to control EAB.  The active ingredient is imidicloprid.  Residents are encouraged to follow the directions.  A demonstration video of using one of these products can be found at https://www.youtube.com/watch?v=wLEVxteP7OQ.

Residents which have an ash tree larger than twelve inches in diameter should contact an arborist to have their ash tree treated.  There are other insecticides that are effective to protect larger ash trees which require special training and certification to apply.  It is advised to get a couple estimates.
