EAB is Here to Stay; Homeowners Urged to Consider Treating Ash Trees for Emerald Ash Borer this Spring

In Wisconsin alone, there are an estimated 834 million ash trees and 37 counties are already under quarantine, including Milwaukee, Ozaukee, Kenosha, Racine and Waukesha counties, to stop the spread of the Emerald Ash Borer.

All Wisconsinites have a role in this battle. Before the Memorial Day holiday and summer travel season begin, mid-May is the ideal time to consider insecticide protection and EAB treatments as leaves begin to return. First Choice Tree Care, located in Mequon and servicing all of Southeastern Wisconsin, is encouraging homeowners to be educated on EAB and the ways to treat and prevent EAB from spreading this spring to help slow the spread of EAB.

What is EAB?

EAB is an invasive pest from Asia that threatens the ash tree population throughout the U.S., where it has already killed tens of millions of trees with no signs of slowing down. The EAB is a small, metallic, green beetle that feeds on wood tissue just beneath the bark. The Asian beetle is nearly impossible to get rid of naturally, as it has few native enemies and has adapted to survive temperatures exceeding 30 degrees below Fahrenheit. Trees infested with EAB typically die within 2-4 years.

A Cure Exits with Proper Treatment and Protection

A cure for emerald ash borer does exits. Research has shown nearly 100% survival with treatment. Protection prior to EAB discovery is most effective, the earlier the treatments, the better chance your trees have of surviving.

The experts at First Choice Tree Care recommend calling an expert arborist to inspect your ash to determine if they are good candidates for treatment. An expert will be able to evaluate the health and value of the tree and then determine if the tree can or should be saved with proper treatment or whether it should be removed.

Emerald Ash Borer Tips

  • The first sign that you have an EAB infestation may be woodpecker damage. Look for peeling or flaking bark as it is a strong indication that EAB are present.
  • Look for D shaped emergence holes in the bark. The holes will be about 1/8 inch in diameter and are a sure sign that EAB has already infested the tree.
  • Other signs include branch die-back, thinning canopy and sprouts growing from the tree base or trunk of the tree.
  • Look for emerald ash borer beetles present during the summer months.
  • Do not move firewood. The law requires that infested wood stay within the quarantine zone. If you have an EAB-infested tree, be aware that EAB can continue to emerge from the wood for two years after cutting.
  • If you suspect you have an infestation, call a tree care professional right away to discuss your options. Keep in mind that treatments are a more economical approach to EAB management than removal or replacement.
