As the trees start to leaf out this year many people in Lapeer County will find that their ash trees are dying from emerald ash borer, an exotic pest that is hitting Lapeer County hard this year. Reporting an emerald ash borer infested tree is not necessary, as the entire county is known to be infested. However, Lapeer County MSU Extension can help you decide whether to take your ash tree down or treat it. Information is available on insecticides to treat trees and choosing trees to replace ash trees. MSU Extension would also like to remind homeowners to pick tree care companies carefully if they decide to remove the tree or have a professional treat it. There are many unscrupulous companies who are taking advantage of homeowners. Make sure the company you select gives you a written estimate and provides proof that they carry liability insurance and insurance on workers before you sign a contract. For more information on emerald ash borer, please contact the MSU Extension office at 810-667-0344.
