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 1,150 City-owned Ash trees that would require treatment in 2023. 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.
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 2022, the EAB program only required the annual soil treatment of “Imidicloprid”. In FY 2023, Emerald Tree
Care, LLC will provide annual soil treatment of “Imidicloprid” and the bi-annual trunk injections using Boxer (a.k.a.
Emamectin Benzoate) for protection against the EAB. Emerald Tree Care has provided a proposal for the scope of
work in 2023, in the amount of $79,464.75. The cost to perform soil treatment is $22,328.75 while trunk injections
will cost $57,136.00. Please see attached for additional information.
Staff recommends continuing soil treatment and trunk injections in Fiscal Year 2023, 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 2023, there is $80,000.00 budgeted for the 2023 EAB Insecticidal Treatment Program in the Capital Projects
Fund Account 08-34-53-4886.
ACTIONS PROPOSED:

Roselle, Illinois, for the 2023 Emerald Ash Borer Insecticidal Treatment Program for an amount not to exceed
$79,464.75
