Question From: r. lebon - Winfield, Missouri, United States
Q: i have a huge hickory tree that has sawdust at the bottom of one side of the tree. th tree doesnt look dead or stressed. I have read on other sites that i can spray the tree with peppermint oil, dish soap and water mixture. Can I pull off the bark to get to these holes?
Ramona, Pulling off the bark can kill the tree. Peppermint oil and dish soap for a mature tree, I don't think so. If you wish to save it get an on-site inspection and recommendation from a professional who has the equipment and products to deal with these insects before they kill your tree.
