ITEM SUMMARY:
Emerald Tree Care, LLC has provided annual Emerald Ash Borer (EAB) treatment services related to the
application of insecticidal treatments, in the form of trunk injections and Basil System Soil Injections, to manage the
spread and negative impact of the EAB since 2011.
There are currently approximately 1,136 City-owned Ash trees that would require treatment in 2024. To date, there
have been approximately 700 Ash trees lost since EAB treatment began in 2011, or about 38% of the original
treatment set. Many of these trees were lost due to storm related damage or other reasons; however, the majority
were removed due to failing health caused by early damage from the EAB. During the same time, the total
diameter of ash trees has grown from 9,201 inches to 17,828 inches, which reflects 93.76% growth.
Daniel Miraval, a board certified arborist, of Emerald Tree Care has provided the City with his recommendation for
continuing with a monitor and treatment program for the City’s Ash trees. Furthermore, Mr. Miraval recommends
the continued use of Boxer for trunk injections bi-annually and soil treatment using “Imidicloprid” on an annual
basis.
In FY 2023, Emerald Tree Care, LLC provided annual soil treatment of “Imidicloprid” and the bi-annual trunk
injections using Boxer (a.k.a. Emamectin Benzoate) for protection against the EAB. In 2024, the EAB program only
requires the annual soil treatment of “Imidicloprid”. Emerald Tree Care has provided a proposal for the scope of
work in 2024, in the amount of $22,995.00. Please see attached for additional information.
Staff recommends continuing annual soil treatment in Fiscal Year 2024, along with continued monitoring of the
City’s Ash trees and conducting an evaluation of all remaining Ash trees to assess the benefits of continuing
application of insecticidal treatments for the EAB.
In FY 2024, there is $40,000.00 budgeted for the 2024 EAB Insecticidal Treatment Program in the Capital Projects
Fund Account 08-34-53-4886.
ACTIONS PROPOSED:

Roselle, Illinois, for the 2024 Emerald Ash Borer Insecticidal Treatment Program for an amount not to exceed
$22,995.00
