Agree with Jeffrey. If pest or mold is visibly obvious then you really should mention it. Include a photo or two. Tell where it’s located. Recommend mitigation by a qualified contractor. Here’s the type of language I typically use for mold, the pest language would be similar:
Mold or mildew and similar organisms commonly occur in areas that show evidence of moisture intrusion or inadequate ventilation. The key to controlling mold is controlling moisture: reduce moisture, remove visible signs of mold, and disinfect surfaces. I am not a mold testing laboratory, therefore the identification of specific types of mold is beyond the scope of the home inspection, and I cannot state definitively whether any specific type of mold is or is not present. When I do smell musty odors or see mold-like substances growing, I note it in my report for you. If you want to know what specific type of mold is present, you should seek the services of a qualified industrial hygienist. According to the Environmental Protection Agency (EPA), a homeowner wearing personal protective equipment may handle small cleanup areas.
