Good Question: What are those purple boxes hanging from trees?

There is an invasion going on right now in the Bluegrass and you may not even know it's happening, but there is an effort underway to try and stop it.

Good Question: Tim in Mt. Sterling writes: I have seen triangular purple containers hanging in several trees, what are they?

Ash trees in Kentucky are under attack.

"They have the capability of killing every ash tree in North America, that's a lot of ash trees." said Dave Leonard, a Lexington arborist.

As an arborist, Leonard is worried about the emerald ash borer.

"He has a rounded belly and a flat back, so they always make this "d" shaped hole." said Leonard.

The emerald ash borer has already hit in Michigan, Indiana and Ohio.

The pesky insect is imported from Asia and its on the move.

The insects feed as larvae under the bark, they eat away at the tree literally starving it to death.

Dave Leonard is on a mission to stop them.

He's ready to lure the emerald ash borer away from tree, he does so with those purple boxes.

"They call them purple triangle, purple whatever, purple kites, they don't know what they are stuck up in the trees."

The boxes are really just traps baited with manuka oil, its supposed to simulate the scent of a stressed ash tree.

Right now there are 6,000 traps across the Bluegrass, they'll be there until August to help Entomologists and Arborists determine just how bad the infestation really is.

If you suspect you have emerald ash borers in your tree, Leonard recommends you call an arborist so they can do a trunk spray on your tree to try and get rid of the insect.
