Treatment for Emerald Ash Borer

1.The Most Effective treatment window for EAB Adults and 1st instar larvae is April, May, first 2 weeks of June 2018.

DO NOT WASTE YOUR MONEY ON TREATMENTS in mid to late summer . Commerical treatements take 1-4 weeks to be effective and DIY treatments take 4-8 weeks so they will miss the peak adult emergence completely if administered after May 2018. Treatments target adults feeding on ash leaves for the 3 weeks before they lay their eggs and 1st instar larvae in the tree. Treatment effectiveness is greatly reduced by end of June / July as the 1st instars are large enough that the treatments do not effectively kill them. Treatments do not kill a substaintal number of larva past the 2nd instar phase. 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!

EAB has been found in: (Coming soon)


4. Call your local extension office if you have any questions before you agree to any treatment (you can find the number by clicking on your county in the map at the bottom of this page.)
