Hi Emily,
Thank you for reaching out as your concern is valid. However, I do not believe HWA or BWA has been detected in the Clarkston area. Because the Michigan Department of Agriculture and Rural Development (MDARD) do the inspections on Christmas tree farms, I would recommend reaching out to them to be sure. MDARD has a hotline: <personal data hidden>.
My first thought was keep a lookout for gypsy moth egg masses! They can be easily removed as one is working with the material. Dispose by scraping off egg masses and soaking in soapy water for 48 hours before discarding. Burning the eggs is also effective (and devilishly delightful).
Good luck with your wreath making event!
