Emerald ash borer (EAB), Agrilus planipennis, is an invasive wood boring beetle from Asia that is predicted to infest all unprotected ash trees in the United States and Canada over the next 20 years. It spreads very quickly and has already killed tens of millions of ash trees since it was discovered in 2002.

If your tree is important and valuable, and does not have a visible infestation, protecting from Emerald ash borer is both affordable and effective. MG tree uses a professional strength insecticide for treating emerald ash borer that can be mixed with water and poured at the base of the tree. Annual treatments are required to maintain protection.
