WORRIED ABOUT THE EMERALD ASH BORER?

THE EMERALD ASH BORER IS HERE...FIND OUT HOW TO SAVE YOUR ASH TREES!
Originally from Asia, the emerald ash borer (EAB) was first discovered in the Detroit area in 2002. It is believed to have entered the country on wooden packing materials from China. The bright metallic-green beetle may be smaller than a dime, but it is capable of taking down ash trees thousands of times its size. Adults are typically ½ inch long and ⅛ inch wide. Eggs are extremely small—approximately 1/25 inch—and are reddish-brown in color. Larvae are white, flat-headed borers with distinct segmentation.
Adults usually emerge in mid- to late-May from infestations to the trees during the previous year (earlier if the weather is warm), with females laying their eggs shortly after. The larvae bore into the ash tree and feed under the bark, leaving tracks visible underneath. The feeding disrupts the tree’s ability to transport water and nutrients, resulting in dieback and bark splitting.
Ash trees are one of the most valuable and abundant North American woodland trees: estimates of total number of ash trees in the United States alone range between seven and nine billion. The emerald ash borer has destroyed 40 million ash trees in Michigan alone and tens of millions throughout other states and Canada. Small trees can die as soon as one to two years after infestation, while larger infested trees can survive for three to four years. Heavy infestations of larval borers speed up the devastation of formerly healthy trees.
We can combat the EAB by treating your trees every other year by way of injection. We inject your trees with a chemical by drilling several small holes at the base of your tree, plugging the holes and then attaching our injection machine to the voids that inject the chemical into the trunk. This chemical works its way up the spine of the tree and kills off the EAB. This treatment needs to be done every 2 years to be effective. If you have a high value Ash tree that you want proactively treat or you think your tree is infected, give us a call and we can set up an appointment to visit with you about treatments.
