For the first time, the Emerald Ash Borer has popped up in Rib Mountain. It was found earlier this month.

Dr. Heather Schlesser with the UW-Extension in Marathon County stopped by NewsChannel 7 at Noon Thursday with what we need to know.

She said the metallic wood-boring beetle attacks ash. It usually kills the trees in one to three years.

Symptoms to watch out for include crown die-back, new growth at the base of the tree, vertical splits in the bark and increased woodpecker feeding. Other signs include 'D' shaped exit holes and 'S' shaped patterns under the bark.

There are several treatment options available:

ACECAP 97 Systemic Insecticide Tree Implants (acephate)

Bayer Advanced Tree and Shrub Insect Control (imidacloprid)

Bayer Advanced Tree and Shrub Protect & Feed II (imidacloprid + clothianidin)

Bonide Annual Tree and Shrub Insect Control (imidacloprid)

Ferti-lome Tree and Shrub Systemic Drench (imidacloprid)

Green Light Tree and Shrub Systemic Insect Killer w/Safari 2G (dinotefuran)

Green Light Emerald Ash Borer Killer (dinotefuran)

Optrol (imidacloprid)

Ortho Max Tree and Shrub Insect Control (imidacloprid)

Ortho Bug-B-Gone Year Long Tree and Shrub Insect Control (imidacloprid)
