The Emerald Ash Borer (EAB) is an invasive insect that is killing off Wisconsin’s ash trees. EAB was first discovered in Wisconsin in 2008 and has been slowly spreading ever since. In the summer of 2012, several new infestations have been confirmed in the state. A recent find in the Janesville area has Madison residents concerned as it seems like only a matter of time before EAB is found in Dane county. In this short video, UW-Madison entomologists Chris Williamson and PJ Liesch demonstrate how homeowners can protect their trees from the emerald ash borer. The treatments shown in the video are annual applications. Once applied, the product protects the tree for roughly a year. Many people choose to make annual spring applications in April or so (right around the time that folks are getting their gardens in order).
