Feeding. Adult emerald ash borers eat ash tree leaves. Larvae feed on the nutrient-rich tissue just under the ash tree's bark, forming S-shaped lines in the tree.

Does the emerald ash borer eat other trees?

Does the emerald ash borer affect other trees? In rare cases, EAB has been found on other trees, such as fringe trees, but EAB mostly feeds on ash trees. In its early stages, EAB tunnels into trees and feeds on the area just underneath tree bark. As adults, the pests eat ash tree leaves.

How fast does emerald ash borer spread?

How does the emerald ash borer spread to new areas? Adult beetles move slowly through the landscape, possibly one mile per year. However, humans can spread this exotic insect long distances by moving infested, firewood, logs, and nursery stock to un-infested areas.

Do emerald ash borers live in dead trees?

Do emerald ash borers live in dead wood? If borers were in the tree when you had it removed, there's a good chance they're still there. So, assume EAB is in dead wood. Don't transport it farther than 50 miles from where it was cut because the emerald ash borers could infest a whole new area.

How can we prevent more invasions from the emerald ash borer?
