Fight Emerald Ash Borer

FIGHT EMERALD ASH BORER: Early detection is key to fighting the emerald ash borer (EAB), a destructive tree insect. Arborjet, a company dedicated to developing remedies for saving ash trees, offers tips on how to spot the emerald ash borer. Look for:

  • Canopy dieback – Beginning in the top 1/3 of the tree, leaves stop growing to the tips of the branches and progresses until tree is bare.
  •  Shoots from the roots – Sprouts grow from the roots and trunk, and leaves often appear larger than normal.
  • Splits in bark — Vertical fissures appear on bark.
  • A tree expert points out the markings left from emerald ash borer larvae on an ash tree. The invasive pest has killed tens of millions of ash trees in the United States and Canada.

    Grooves and D-shaped exit holes – Feeding galleries, or grooves, for larvae weave back and forth under the bark. Adults form D-shaped holes when they emerge from under the bark.

  • Increased woodpecker damage – These birds peck at outer bark while foraging, and create large holes while extracting insects.
  • Here’s more information about emerald ash borer.

We can now fight back! There is a product, TREE-age, by Arborjet, that we can inject every other year that has shown over 90% control of the larvae that kill the tree. The injection is best done as a preventative, but we have had some success in trees with limited infestations.

ARBORjet.02The trees are dosed in milliliters. For example, a 12″ diameter ash requires just over 40 milliliters of TREE-age and costs about $150 + tax, every other year.  Not a whole lot of money to protect a prominent ash tree in your landscape.

If you have any ash trees that are currently not under our care, please contact us for a no-cost or obligation inspection to provide our recommendations. We might be able to protect your valuable ash tree, allowing you to enjoy its benefits for many years to come. And, if you have any neighbors or friends with ash trees, we always appreciate a referral. Call us at 440-4521-9589 or email

Deadlier than Dutch Elm: U.S. Trees Stricken by a Plague of Ash Borers

By ANITA HAMILTON Wednesday, May 25, 2011

A voracious beetle known as the Emerald Ash Borer, first discovered in Detroit in 2002, has been gradually spreading, leaving a trail of destruction in its wake. The infestation has already killed some 60 million ash trees in fifteen states as far east as New York, and as far south as Tennessee. The toll of dead trees will likely surpass those felled Dutch Elm disease by the end of this year. “It is now the most destructive forest insect ever to invade North America,” says Deb McCullough, an entomologist at Michigan State University.

Ash borer season is in full-swing — the beetles mate and lay eggs in May and June. The bug is native to China and likely migrated stateside burrowed inside wooden shipping pallets. It has few predators in the U.S., which is one of the reasons the rate of the outbreak is unprecedented. But it is also very stealthy, because its larvae, which feed on nutrients just below the bark that keep the tree alive, are usually not visible until the tree is already in the ICU. (The mature beetles merely munch on leaves.) There are an estimated 8 billion ash trees in the United States. “It’s causing complete mortality of ash trees,” says researcher Dan Herms of Ohio State University, who notes that none of the 16 species of ash in the U.S. is resistant to the pest.

Where Do Emerald Ash Borers Spend Their Winters?

We continue to apply our Annual Fall Insect Control Soil Injection treatments to ash trees that will provide season-long protection from the emerald ash borer next year (2011). We also apply this treatment to target insects which attack other trees and shrubs, including birches, honey locust trees, boxwood shrubs, and magnolias. Call our office at 216-381-1700 or email me at if you and ash tree(s) or one of these other trees or shrubs in your landscape.

Is Ohio’s War Against the Emerald Ash Borer Over?

As reported in the Cleveland Plain Dealer today (Tues 09/21/2010), the Emerald Ash Borer (EAB) insect has now been found in all eighty-eight (88) of Ohio’s counties.

Ash trees in your landscape CAN be protected from attack by the EAB.  We are applying our annual insect control soil injection treatments now which will protect ash trees from EAB attack in the ’11 season.  These treatments have been shown to be over 90% effective in protecting ash trees.  Forest City Tree Protection uses this same treatment to protect honey locust trees from aphids, plantbugs, and calico scale; birch trees from borers, leafminers, & aphids, and magnolias from magnolia scale.  Contact our office at 216-381-1700 or via email to to have an arborist inspect the ash, honey locust, birch, and magnolias in your landscape and provide a no-obligation quote for an annual Fall Insect Control Soil Injection application.

Ohio’s war against the emerald ash borer is over: the bug won |

Deadly Emerald Ash Borer Confirmed in Shaker Heights

The adult stage of the Emerald Ash Borer (EAB). This is the mobile stage (it flies), the one which initially infests a tree by laying eggs in the bark crevices between mid-May to mid-August. The bright, metallic green adult is 1/2 inch long, has a flattened back, and purple abdominal segments beneath wing covers.

Last Friday (July 9, 2010), a Forest City Tree Protection crew identified our 1st confirmed case of an ash tree killed by the Emerald Ash Borer insect (EAB) in the City of Shaker Heights.  While removing a dead ash tree on a client’s property, the crew found the typical serpentine (S-shaped) feeding galleries created by the EAB larvae.  After EAB eggs hatch, the young larvae chew their way through the bark into the cambium, or growing layer of the tree trunk.  As the larvae mature, they continue feeding the the xylem tissue of the most recent annual ring.  This is the tissue the tree uses to translocate water & elements upward from the roots and sugars & starches made in the leaves down to the roots.  The larval feeding galleries weave back and forth across the woodgrain, disupting the movement of water, elements, starches, & sugars.  This in turn leads to the rapid demise and death of the ash tree.

When the EAB larvae mature and transform, the adults emerge through D-shaped exit holes in the bark, starting the life cycle all over again.  Noticing one of these D-shaped holes on the bark of a lower trunk section from the ash tree they had removed, our crew peeled away the bark, finding a large, mature EAB larvae and its S-shaped (serpentine) feeding galleries.

Pulling back the bark from the D-shaped exit hole, the crew found this well-fed and destructive European Ash Borer larva. (photo by Lauren Lanphear 07/09010)

Peeling away the bark on a section of trunk from ash tree we removed in Shaker Heights, the crew disovered the telltale serpentine feeding galleries of the European Ash Borer larvae. The tissue destroyed by the formation of these feeding galleries leads to a quck decline & death of the tree. (photo by Lauren Lanphear 07/09/10)

We brought the section of trunk back to our office where we could photograph the larva and its feeding galleries. We were able to extract the EAB larva from the trunk and get this picture.

We sent the above three (3) photographs to several entomologists with the Ohio State University and received confirmation of our diagnosis.

Once an ash tree is infested with EAB, the only option is removal.  However, there are highly-effective treatment options to protect healthy ash trees from attack by the EAB.

We will be applying insect control soil injections this fall (Sept) to protect ash trees from EAB next season (2011).  The average cost of an EAB protective treatment is $5.75 per inch of trunk diameter (across, not around).

If you have one or more ash trees on your property that you’d like to protect, call our office ASAP (216-381-1700) to have one of our ISA Certified Arborists inspect your tree(s) and provide a proposal.
