If hemlock trees on your property show signs of hemlock woolly adelgid infestation, now is a good time to plan for spring treatment of this invasive species. Hemlock woolly adelgid (pronounced \\ -\u0259-\u02c8del-j\u0259d \\<\/a>), native to Asia, has been detected in Allegan, Ottawa, Muskegon Oceana, Mason and Benzie counties in Michigan. These small insects suck sap from hemlock twigs and ultimately can cause tree death.<\/p>\n\n\n\n

Insecticides are available to control the insect, and in many cases, landowners easily can apply them by carefully following label instructions and application rate guidance. Due to certain restrictions on the use of these insecticides, you may need the services of a licensed pesticide application business.<\/p>\n

If one or more trees are infested, make plans to act this year. Without treatment, trees with hemlock woolly adelgid are likely to die within four to 10 years. Weakened trees on a home landscape could spell disaster during high winds or storms, and eventually they will have to be removed. Loss of hemlocks in forested areas can reduce shade, winter cover, food and habitat for birds, fish and mammals.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Products containing either imidacloprid or dinotefuran as the active ingredient and labeled for use on adelgids are effective in combatting the insect.<\/p>\n
