Keep Your Trees Healthy and EAB free With Our Effective Emerald Ash Borer Treatment Services.

EAB is an invasive pest that will attack and kill both unhealthy and healthy ash trees in the area it is present. The larvae of this wood-boring insect tunnel through the water and nutrient conducting tissue just under the bark, cutting off supplies to the crown of the tree and causing a drought-like die back in the crown. EAB will kill an infested tree within 3-5 years of first attacking that ash. Other signs and symptoms of EAB presence in a tree include epicormic sprouts low on the trunk, S-shaped larval galleries under the bark, and D-shaped exit holes on the bark.

Now that EAB is confirmed here, homeowners in the Boulder County area must now start considering their options for the ash trees on their properties. If a tree is determined to have EAB present and more than 30% crown dieback, the tree must be removed and disposed of properly. If there is no EAB present in the tree and the crown is healthy, there are recommended treatments to help keep your ash trees healthy and EAB free! If there is no EAB present but the trees is unhealthy (drought stress, native ash borers, ect.) or undesirable (bad location, poor structure, ect.), or not located close to a known infestation, the homeowner may decide that no treatment or removal is necessary at this time.

Treatment for EAB includes applying a systemic insecticide to be taken up into the tree through either the roots (soil injection) or through direct truck injection and transported through the tree by the water and nutrient conducting tissue in the trunk and branches. This tissue is the same material that the EAB larvae eat, and the pesticide will kill the larvae before they are able to do significant damage. The method of application and chemical used will depend on the size of the tree to be treated.
