Cold snap will not kill Emerald Ash Borer Larvae in Iowa

Posted: Updated:
MARION (KWWL) -

The recent weather, while very cold, was not cold enough to save trees.

While reports out of Minnesota said the recent cold snap could kill some Emerald Ash Borer Larvae, officials with Trees Forever in Marion told us it has to be 38 degrees below zero for two days in a row to kill the larvae.

They say those bugs will likely destroy all of Iowa's ash trees over the next 15 years even if we get that kind of cold weather.

"It could maybe draw out the abilities that communities have to prepare for Emerald Ash Borer," said Dustin Hinrichs, with Trees Forever. "I don't think it would completely wipe the threat out because there's still going to be a lot of areas where it did not get that cold."

There are treatments for ash trees to try to protect them from the Emerald Ash Borer. However, people with Trees Forever say it's best to plant new trees, a mix of trees that aren't ash trees.
