2021 Bay County Emerald Ash Borer (EAB) Treatment
Treatment to Protect Publicly Owned Ash Trees occurred June 14-16, 2021
Ash trees make up a large portion of the public trees that line our streets and fill our local parks. The Bay County Gypsy Moth Suppression Program realizes the value of trees and works to protect these trees from invasive pests such as the Emerald Ash Borer (EAB). The EAB lays eggs on the bark of Ash trees and the hatchlings bore into the tree bark. Once inside the bark layer of an Ash tree, the EAB chews through the tree’s water and nutrient-conducting tissues essentially starving the tree. As the tree begins to die the leafy canopy of the infested Ash tree will begin to look thin. That’s why we will be conducting treatments to continue protecting publicly owned Ash trees in Bay County from the invasive Emerald Ash Borer between June 14-16, 2021.
The Ash trees were treated through the direct injection of an insecticide called Tree-age that contains the active ingredient Emamectin Benzoate which will kill 99% of EAB that feed on it. Since the product is injected directly into the tree through a one way port, there is no danger of the product leaking out of the tree and affecting non-target organisms. EAB treatment timing is dependent on the leaf development of the Ash trees that will be treated. The Ash trees need to be actively transpiring or moving water through the tree to take up the insecticide. Treatment of each tree is estimated to take from 15 minutes up to two hours. The 2021 Emerald Ash Borer Treatment Project treated approximately 971 Ash trees. These treatments will protect the trees from EAB for three (3) years. The application firm conducting the injection treatment for Bay County will be Kinnucan Tree Experts & Landscape Company.
Specific areas of publicly owned Ash trees included in the 2021 treatment project were located along streets and in parks in the locations of Frankenlust Township Park, Monitor Township Park, all publicly owned Ash trees located on the west side of Bay City, and all northern Bay County publicly owned ash trees located in parks and along streets in (Gibson Township, Pinconning, Linwood, and Kawkawlin). Maps showing the general locations with Ash trees to be treated can be viewed below

Emerald Ash Borer
The Emerald Ash Borer (EAB) is an Asian beetle that moved into the south-east corner of Michigan some time in the early 1990's. It's larvae feed on the cambium or conductive tissue just under the bark of ash trees. They only feed on ash trees and will usually kill the infested tree within 1 to 5 years. Though the infestation was first discovered in 2002 in the Detroit area, this aggressive beetle is now found throughout the lower peninsula of Michigan and in 13 additional States and in two Canadian provinces. (To see the EAB locations map please click HERE.)
In 2004, voters in Bay County approved the renewal of the Gypsy Moth Millage with the inclusive language of "other invasive, non-native pests, such as the Emerald Ash Borer (EAB)". This will allow the Gypsy Moth Suppression program to address the problem of the EAB when it is found in Bay County. The EAB Plan of Action outlines the actions which will be undertaken by the Bay County Gypsy Moth Suppression Program with regard to the EAB.
In 2005, the Emerald Ash Borer was found in southern Bay County.

Emerald Ash Borer (EAB) Multi-State Location and Quarantine Map
The Federal Quarantine no longer prohibits the movement of ash wood products from Michigan to parts of Ohio, Indian, Illinois, and other areas in the "generally infested" areas of the country as long as the products do not leave the generally infested area. To see where the Emerald Ash Borer (EAB) is, check out the EAB Multi-State Location Map and Michigan Department of Agriculture EAB Quarantine Map
Treatment of Emerald Ash Borer (EAB)
Present treatment technology is available to treat individual trees and homeowners are encouraged to use these treatments to protect their ash trees. However, the high cost of treating individual trees limits the actions of the Bay County Gypsy Moth Suppression Program. The EAB Plan of Action outlines the actions which will be undertaken by the Bay County Gypsy Moth Suppression Program with regard to the EAB.
