Pests on trunk of Japanese maple
Want to know what they are and how to eliminate them. I did not see a description in your website that was even close to how these bugs looked. I don't want them spreading to other trees. We have lots of trees nearby on the property.
Without an image to identify the pests my recommendation would be to treat the insects with Neem Oil.
Neem Oil is organic and is safe for people, pets and bees.
It works as both an insecticide and fungicide.
Here are some articles with more information.
You can upload an image to our Q & A page to help with identification.
