Emerald ash borers are the talk of the arborist town, and not in a good way. These small beetles are wreaking havoc on ash trees throughout the country, and with the invasive species recently showing up in the Front Range, it is more important than ever to be prepared to handle what is almost inevitable. The first step in preventing a major infestation is education, so today we’d like to share some of our knowledge about the emerald ash borer with you.
What Is It, And How Do I Know If My Trees Have It?
The emerald ash borer (EAB) is the most destructive forest pest in North American history and has caused billions of dollars in damage, destroyed millions of trees, and put every ash tree at risk. The beetle is native to northeastern Asia, and while scientists are unsure exactly how it got here, it is hypothesized that they most likely came in ash wood that was used for stabilizing cargo ships. There are not enough natural enemies of EAB, which means it is an invasive species that continues to grow and destroy trees.
