I write a about a week ago about my Bradford Pear losing bark. I took a
closer look and there are several holes under the loose bark. The holes are
about 1/8" in diamater. I bought some kind of pesticide oil from Home Depot
that I can spray with a sprayer and water hose. I have no idea if this will
work but I'll give it a try.

Also, should I do anything to the tree where the bark fell off to protect
the tree? Will the bark ever grow back or will my tree die next year?

Thanks,
Gary
