Rainbow Treecare <br />understands that quantity of trees available for treatment will be determined by the City of <br />Arden Hills. All technicians assigned to this project will be drawn from Rainbow Treecare's staff <br />and will be licensed commercial pesticide applicators in the State of Minnesota. <br />The cost for this project will be as follows: <br />• $5.15 per diameter inch— City property oak tree injection service with Emamectin <br />benzoate initiated by City staff <br />
