When applied correctly, EAB treatment is 85 to 95 percent effective. EAB treatment works to save trees in your yards and your city. For example, when EAB was detected in Naperville, IL, they treated their trees. Three years later, more than 90 percent of the treated ash trees show no signs of infestation.
Beside this, how often should you treat for emerald ash borer?
Treatments are not a one-time occurrence. They do not immunize the tree for life. Ash trees to be saved will likely need to be treated every one to two years, depending on the type of treatment.
Besides, how long does Ash Borer treatment last?
If I decide to treat my ash tree, will I have to treat every year? In most cases, yes. Most insecticides registered for EAB management require yearly applications to effectively protect a tree. Products containing the active ingredient emamectin benzoate, are labelled for two years of protection.
Within its native range in Asia, emerald ash borer is attacked by a variety of predators including several species of parasitoid wasps that specialize on the beetle's eggs or larvae.
