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.

    The markings (feeding galleries) 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.

  • The markings (larval feeding galleries) 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.
  • 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.

Emerald Ash Borer Decimating Environment in North America

Maine basket weaver splits off strips of brown ash.

Unprotected ash trees are susceptible to fatal attacks by the Emerald Ash Borer insect, “the cause of a looming environmental and cultural disaster in the northeastern quarter of the North American continent.” Forest City Tree Protection offers annual Insect Control Soil Injection applications which can protect ash trees from this devastating pest. Call or email us to for a no-obligation quote on protecting your ash tree(s). 216-381-1700 or

The emerald ash borer is surprisingly beautiful, as beetles go. It has a pleasingly streamlined bullet-shape, a bright, metallic emerald green shell, and a bright red, metallic dorsal surface. But you may be seeing it soon on “wanted” posters, because this tiny insect is the cause of a looming environmental and cultural disaster in the northeastern quarter of the North American continent.

The emerald ash borer, which is just one-half-inch long, is busily wiping out more than a billion ash trees in the United States and Canada, wreaking ecological havoc on watersheds and forests, as well as the economies of more than 10 states and provinces, and doing incalculable damage to Northern Woodlands tribal cultures. Kelly Church, a member of the Grand Traverse Band of Ottawa and Chippewa Indians and a nationally acclaimed basket weaver, is one of the leaders of the battle against the emerald ash borer. She’s determined to preserve Northeastern tribes’ cultural traditions against this onslaught, even if it takes generations.

Known as EAB, the beetle was accidentally imported from Eastern Asia in the late 1990s, possibly in cargo pallets. Since then, the minuscule insect has made itself at home in the U.S.’s vulnerable ash trees. (Asian ash trees are resistant to the borer’s effects.) EAB females bore into an ash’s bark and lay eggs. The resultant larvae bore further into the tree and into the cambium, the area between the bark and wood where nutrient levels are high. The larvae kill the trees by destroying the water- and nutrient-conducting tissues under the bark. Once an infestation is noticed—an obvious sign is the thinning of a tree’s canopy—it’s already too late: The tree is doomed. So far, researchers are unable to halt the infestation, and mortality is virtually 100 percent. EAB has killed tens of millions of trees in Michigan alone.

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.

Poster shows life cycle of the emerald ash borer as it hatches and matures during the 12 months of the year, from egg to larva to adult.

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 |
