I had to have a termite treatment plan last year due to termites being present. I had to finance this service. Can I write this off or the interest??

If this is for your residence the interest is not deductible unless it is mortgage interest.  Mortgage interest is interest on a note secured by a mortgage (or second mortgage) on the home and perfected usually by recording in the public records of the county where you live.

If it is an unsecured note, it is not deductible.
