Emerald Ash Borer

 

 

EABThe Emerald Ash Borer (EAB) is a half-inch long metallic green beetle whose larvae feed under the bark of ash trees. Their feeding eventually girdles and kills branches and entire trees. The EAB was first identified in North America in southeastern Michigan in 2002.

In the years since that discovery, the beetle has spread through much of the United States, including Pennsylvania. EAB was detected in Lancaster County in 2015 and Montgomery County in 2014.  It will likely be found in Chester County within the next year.   Once it is discovered within East Bradford Township it will kill most of the Ash Trees within the next 4-8 years.

The Emerald Ash Borer is coming to East Bradford …  Are you ready?

FAQ’S

The answers to the following questions were compiled from reviewing State, Federal and University websites (see list above) and several EAB management plans. This is the most current information available and reflects the experience of communities that have already seen the damage of the EAB.

Which trees can and should be saved?

  • Healthy and vigorously growing trees with more than 75% of their leaves.
  • Trees located in a site that enhances the landscape and does not threaten structures, roads or power lines.
  • Trees that are valuable to the owner.
  • Trees that show no signs of decay or infestation with EAB or other insects. No woodpecker damage or decaying trunks.

 

What is the safest and best treatment option?  One of the environmentally safest and most effective treatments is injection of an insecticide under the bark. This should be done in early spring when tree is actively growing.

How often should trees be treated and for how many years?  Trees should be treated every 3-4 years if using trunk injection (Treeage). Treatments should continue until the infestation has passed (10-15 years).

When should treatment start?  When the EAB infestation is within 10 miles of your yard.

How much does the treatment cost and would removing the tree save money?  Treatment costs depend on the diameter of the tree and the number of treatments. Removal costs also depend on size of the tree and its location.

Should I wait to remove my ash trees?  Ash trees will die within a year after EAB infests. Ash trees become very brittle when they die and tree companies will not climb them for removal if they have been dead for more than 6 months. Depending on the situation a crane may be needed thus increasing the cost.

How soon before EAB is in Chester County?  EAB was detected in Lancaster County in 2015 and Montgomery County in 2014. Most likely it will be here in the next year.

Will all ash trees die if they are not treated?  Yes. In Lower Michigan over 95% of non-treated ash trees have died.

Are property owners responsible for removal or maintenance of trees within the road right of way?  Yes.  For local roads owned by the Township and for private roads it is the responsibility of the adjacent property owner.

Should I plant new trees to replace removed ash trees?  Yes, trees provide many environmental benefits such as energy savings, stormwater management and animal habitats. Removed trees should be replaced with suitable species.

Can I use the wood from fallen ash trees?  Yes, but DO NOT move wood from this area. Also never bring firewood/wood into this area, as it may be contaminated!
