Emerald Ash Borer (EAB)
Japanese Beetle

Emerald Ash Borer (EAB)
The removal of Village-owned ash trees in Hoffman Estates due to the Emerald Ash Borer (EAB) is substantially completed. Remaining ash trees include those treated by residents and homeowners associations. Public Works crews and contractors have removed over 6,000 ash trees via this program.

The Department of Public Works is proud to report that the planting of replacement trees is also substantially completed. Over 5,500 trees have been planted as a result of the EAB replacement program. In some cases, removals will not be replaced due to overcrowding or concern for the health of other existing trees.

Due to the large number of trees planted in a short period of time, the Village is unable to water all replacement plantings. Residents who have received replacement trees are encouraged to continue watering the plantings regularly to improve their chance of survival. Additional watering is essential in the first several years after a tree is transplanted. More information on the Emerald Ash Borer can be found on the Morton Arboretum's website.

Japanese Beetle
Japanese Beetles continue to be a problem for residents of Northern Illinois, including the Village of Hoffman Estates. Leaves of affected trees will appear to be eaten with only the veins of the leaves remaining (skeletonized), which make the leaves appear similar to lace. As the impact of Japanese Beetles is largely aesthetic and typically not detrimental to the health of trees, the Village does not treat Village-owned trees for this issue.

More information on the Japanese Beetle can be found on the Morton Arboretum's website.
