Emerald Ash Borer Specialist in Okoboji, IA

Common signs include thinning leaves, dead branches near the top of the tree, shoots growing from the trunk, increased woodpecker activity, and small D-shaped holes in the bark. If you notice these symptoms, have your ash tree inspected to determine whether Emerald Ash Borer is the cause.

Yes. Emerald Ash Borer larvae feed beneath the bark, disrupting the tree’s ability to transport water and nutrients. Infested ash trees typically decline over several years, and heavily damaged trees may become hazardous as branches die and weaken.

In many cases, healthy ash trees can be protected with appropriate preventive insecticide treatments. Treatment is generally most effective before significant damage occurs. Trees with extensive canopy loss may be too damaged to recover, so an inspection can help determine the best option.

Spring is generally the preferred treatment period, particularly mid-April through mid-May for many treatment methods. The ideal timing depends on the product and application method, so consult a qualified tree care professional about the best schedule for your property.

Not necessarily. If the tree is healthy enough, treatment may be an option. However, if it has extensive dieback, severe structural damage, or poses a safety risk, removal may be the better choice. A professional assessment can help you decide whether treatment or removal is appropriate.
