The frequency of treating trees for ash borer depends on several factors, including the level of infestation in the area and the type of treatment used. Generally, preventative treatments, such as insecticides, should be applied annually or every other year. If a tree is already infested, treatments may need to be done more frequently, often every 6 to 12 months, to effectively manage the infestation. It's essential to consult local guidelines and experts for specific recommendations based on your region.
