As long as you have treated it, it's not a problem. Same with termites, radon, wood rot, and anything else in a house. All houses eventually have to have something repaired, replaced, fixed, or treated. The older houses tend to have had more things addressed simply because of their age. If I were you, I would take photos of before and after and also have an inspector take a look at your work AFTER you have completed your remediation. You may or may not want to include the photos when/if you sell the house but at least you will have the option of doing so.
