Yes, I understand that and took that away from the instructions. I got some all the same to be proactive around my buildings.Termidor is not for interior living space use. I thought the pics were of an exterior view of the chimney.
As I recall it allows for spot treatment in the instruction, and so I’ll either follow instruction with that or get another product.
The chimney is not outward facing, it’s inside but in a completely unfinished building that is not well sealed at all, fwiw.
