Harmful Insects

Elm Leaf Beetle

Elm leaf beetles are one of the most common pests found on all types of elms in Minnesota. The insects feed on the leaves, causing them to dry up and die. Heavily infested trees have an unsightly brown appearance. Repeated, heavy infestations weaken a tree by decreasing the amount of food it can manufacture with its leaves. Trees low in stored energy are prone to branch dieback, and decline. Adult elm leaf beetles are also nuisance pests in houses. Large numbers of beetles may seek overwintering shelter in and around homes and come out of dormancy over the course of the winter. To learn more see the attached information sheet.
