I realize that in California one must be licensed by the structural pest control board to officially call out an active termite infestation, but as a home inspector should we mention evidence as “possible wdo evidence” when we see droppings (drywood termites). Case in point, I found a pile of pellets adjacent to a water heater base. I feel like I should mention it, but I’m not sure if I’d be opening a can of worms by stepping on the termite inspectors toes. (i’m a formerly licensed WDO inspector in California)
I have pointed out observations and then qualify to what ever degree you are comfortable
i.e. dry wood/subterranean. Do not remark as to it being active or not, simply refer it on to a licensed specialist.
