ST. PAUL, Minn. (AP) — As spring approaches, bug experts say now is the best time for Minnesotans to look for signs of emerald ash borer.

The Minnesota Department of Agriculture urges homeowners to search their ash trees for potential infestations, especially those in and near the quarantined counties of Hennepin, Ramsey, Houston and Winona.

Entomologist Mark Abrahamson says it's an ideal time for homeowners to go into their yards and look.

He recommends looking woodpecker damage. Woodpeckers like ash border larvae, so woodpecker holes may indicate the presence of EAB. And it recommends checking for bark cracks. EAB larvae tunneling under the bark can cause it to split, revealing S-shaped tunnels underneath.

Those who suspect an ash tree may be infested should contact a tree care professional, a city forester, or the agriculture department.
