Insect treamment for Red Maple?
My Red Maple is infested with these boring insects. The wood just powders right off. There are pinhead size and walk very fast. There seems to be other insects as well. I also have several Autumn Blaze Maples that have similar infestations, including some caterpillars. These are my second round of Maples that I have, and I am done with replacing them. Clearly, I live in an area (farm area) where these trees attract these pests. Is there any treatment I can purchase locally, that can save these trees? If they die, I am not replacing them. There are nearly 5 years old. Also, does that tar-like repair coating at Lowes, help?
