Seasonal Monitoring Guide for Emerald Ash Borer

Monitoring at the right time, June through August helps focus our monitoring efforts, improving efficiency and increasing the chances of early detection for a rapid response.

According to recent research, conservative monitoring windows range from early July through early August.

Varying temperatures in time frames and in intensity can extend this window from early June to mid July.

Advances in early detection of Emerald Ash Borer

Predictions of when emerald ash borer may establish in jurisdictions have the potential to change the historical impacts on ash trees in cities. By the time EAB had established itself in 2002, it was too late to contain its spread. This led to millions of trees being lost.

Intensive research and field work has led to the creation of predictive models that can provide ‘forecasts’ of when EAB may be most active and easier to detect.
