Crews injecting trees to prevent spread of EAB

Posted: Updated:
MADISON (WKOW) -- Madison officials are working hard to get rid of an invasive species, the emerald ash borer.

On Friday, city officials demonstrated how ash trees are being injected with a chemical to control the EAB.

The environmentally friendly chemical kills ash borer larvae and protects the tree from infestation for two to three years, before another injection is needed.

The city of Madison has an estimated 21,700 publicly owned street ash trees.

Mayor Paul Soglin says they're working to preserve about 65% of them, " This is a program that will take several years, were not going to be able to tackle it overnight."

Currently, 22 Wisconsin counties are under state quarantine for EAB infestation.
   
The tiny green beetle was found in Madison last fall.

The trees were in the north and east side of the city.
