Emerald Ash Borer (EAB)
The emerald ash borer (EAB) has destroyed tens of millions of Ash trees throughout the US and Canada. Originating from Asia, the emerald ash borer can now be found in the eastern United States and parts of Canada – and is spreading fast. Some of the symptoms of EAB: thinning or dying of ash tree crowns, suckers at the base of the tree, splitting bark, tunneling under the bark, D-shaped exit holes and woodpecker activity. Thankfully, there are highly effective insecticides currently available to prevent the destruction of Ash trees. Willow Tree Service uses such treatment through trunk injection which targets the destructive EAB larvae inside the tree. When used as a preventative, the treatment provides 2 years of protection from EAB. For more information visit:
