ROCHESTER, Minn.-The Forestry Division of the Parks & Recreation Department are starting their annual inspection to control Emerald Ash Borer or EAB.
EAB is a beetle native Asia. The adults are described as metallic green winged beetles, the length of a penny.
Alison Litchy is the City’s Forestry program coordinator.
She tells KIMT that the bug was first discovered in 2002 in Detroit, Michigan.
In 2010 they were confirmed in 15 states. Now in 2016, the bugs have been in 29 states.
Why are they invasive?
“The larva cuts off channels for the tree to survive,” she added.
Alison tells KIMT that the EAB larva survives on ash trees.
“If not treated the tree will die,” she said.
Minnesota has one billion ash trees across the state and 5,800 of them are in Rochester.
EAB adults can fly up to six mile to mate and lay their eggs on the bark of the ash trees, meaning they can spread fast.
From November 1 through December 31st, The city will be inspecting ash trees on public and private property to look for signs of EAB.
The city will treat infected trees by either removing or injecting insecticide.
