1,700 Ash Trees Will be Injected With Insecticide in September

Wachtel Tree Science workers are marking public ash trees that will be treated with insecticide to prevent emerald ash borer from spreading to the village.

Wachtel is out this week placing a small fluorescent green dot at the base of 1,700 ash trees that will be treated with imidacloprid. The treatment process will begin in early September and conclude in early to mid-October.

The preventative insecticide treatment will be injected with a soil probe closed injection system 6 inches to 1 foot below the soil line and within approximately 6 inches of the base of the tree. The soil injection process will occur between the curb and the sidewalk, adjacent to the tree.

Adjoining property owners of those public ash trees that will be treated will be sent notices by mail with additional information on the project.

The village has to prevent emerald ash borer in the village. This year, the village spent $278,338 to treat, remove and replace ash trees:

• $137,370 to T&T Tree Service to remove 202 ash trees ranging in size from 20 inches in diameter to 32 inches in diameter

• $93,539.40 to Johnson's Nursery to plant 202 non-ash tree species in place of ash trees that have been eliminated.

• $47,429.80 to M&M Tree Service to treat 1,700 existing ash trees.
