There’s a big old tree in my back yard with a large hole about 40 feet up. Last week I had a tree service guy take a look at it. He said the tree was generally healthy but would benefit from some “treatments” over the summer. I gave him $350 in advance to do the work and almost immediately felt like an idiot for doing so.
So today he shows up for the first treatment and tells me that the tree needs more work than he thought. He wants to fill the hole with tar. Also, he says that the hole is infested with termites and carpenter ants, which need to be killed in order to protect the tree and keep them from spreading. He asked for another $400 to do the work. When I balked, he said he could do it cheaper by using diesel oil, instead of insecticide, to kill the ants and termites.
I haven’t been able to find information on the Web about using diesel oil for this purpose, but something tells me it’s a bad idea. Something is also telling me that the guy is playing me.
I’d appreciate any expertise, opinions, or experiences y’all might have.
Two years ago a different tree service told me the tree needed to come down; they wanted $3000 to do the job.
