or EAB, is an invasive insect that has already killed tens of millions of native trees in the US and threatens millions more. Help slow the spread of EAB by checking your ash trees for these common signs and symptoms of infestation: overall foliage thinning and dead branches; on the trunk look for woodpecker damage, bark splitting and D-shaped exit holes! EARLY DETECTION IS KEY
Despite their flashy metallic color these beetles are difficult to spot and cause significant damage by the times symptoms become apparent. Emerald ash borer larvae feed beneath the bark of an ash tree, cutting off water transport to the rest of the tree and killing it.
In as little as two years from when symptoms are first observed most of the branches can die. However, when infestations are detected early damage from EAB can be slowed down saving more of our ash trees.
