Emerald Ash Borer

Emerald Ash Borer

An environmental scientist says if you have ash trees in your yard, be on the lookout for the emerald ash borer.

The destructive insect has been sighted in 2 counties, said Stephen Hauss with the Delaware Department of Agriculture.

"We've seen it in New Castle and Sussex--we just haven't seen it in Kent County yet.  It might be there.  You know, these other places, they probably stayed at a really low level until recently, when we started to see them this year," said Hauss.

Hauss added if your trees have been victimized, you'll see telltale signs.

"There's some other diseases that could trick you, but the best thing to do would be to just look at the general health of the tree--if it looks like it's losing leaves, that could be a sign that it might be infested," said Hauss.

Hauss said if your ash trees are infested, your options are to treat or remove them, and added the invasive spotted lanternfly could be an even bigger threat to local plant life, because it targets more species.
