Treatment for Emerald Ash Borer

1. The window for the Effective treatment of Ash for EAB has closed for the 2014 growing season. DO NOT WASTE YOUR MONEY ON TREATMENTS this late in the season. We have reached enough growing degree days for Peak EAB emergence to occur. Commerical treatements take 1-4 weeks to be effective and DIY treatments take 4-8 weeks so they will miss the peak emergence completely. Treatments target adults feeding on ash leaves for 3 weeks before they lay their eggs. Treatment effectiveness is greatly reduced by end of June / July. Treatments do not kill a substaintal number of larva once they are actively feeding in the cambial zone as most of the chemical is found in the xylem portion of the tree. For more information related to treatments see pages 5-9 of the newly released info June 2014 publication

2. There are NO treatments on the market which are a one and done cure-all! You will need to treat every 1-3 years depending on product used. Injection treatments will do damage to the vascular structures in the tree so don't start before the infestation arrives in your town! Here is a research paper published in 2010 which details the research behind the treatment recommendations

3. Be carefull of the random "knock on the door" and the pressure sales tactics. Reputable companies will not do this and in most cases, if you call a local company, they will try to dissuade you from treating your trees until EAB is found within 15 miles of your home!
