The Great Cankerworm Count


The Great Cankerworm Count. Help us conquer the canker.

Want the Cankerworms to Stay Away?

So do we! We hope that increased monitoring will enable us to proactively band in areas that need it and keep the numbers low.

Become a Citizen Scientist!

We think you can help! Become a citizen scientist this winter and help us collect data on cankerworms. We will send your data to Clemson University to analyze. With your help, we hope to understand the cankerworm population in Charlotte and possibly predict the next infestation.

Ready to get started? Follow these steps.

Step 1: Measure Your Tree

Pick one large tree in your yard. Wrap a string or tape measure around the trunk approximately 4 ½ feet from the ground. Enter the length (circumference) in inches on the form.

Step 2: Band Your Tree

You can hire a professional to install the band(s), or you can do it yourself. 

Step 3: Start Tracking!

If you're really excited about counting, feel free to check once a week in February and record the numbers you are seeing. Remember to squish the moth after you count it so it doesn't get counted twice.

Super quick option! If you don’t have a lot of time, check once in February and submit the information to us.

Step 4: Send Us Your Data

Once you've finished tracking, enter your data online, or send it to us by mail, by fax or via email.
