Please help clarifying termite responsibility

I live in a 4 unit townhouse. Im on the end of our four units and was wondering if I could get some help.
I noticed on the floor of our interior wall something resembling termites. I have a professional coming out tomorrow to confirm. From what I have been reviewing in the CC&Rs the termites are owners responsibility unless its common area. The wall that is showing signs is the only wall that is not shared by my neighbor and is constantly hit with sprinklers and suppose to be maintained by HOA. There is also a maintance door on the outside of the wall that workers and the utility company can access. Last year the maintance door rotted off its hinges leading my to belive that maybe its coming from there. Should I notify the managment company about problem or is it something that I need to handle myself. Also our home is up for sale and would like to take care of before inspection so we can get ahead of it. Thanks so much

You need to advise your HOA immediately. The walls of your townhouse are likely common element and the HOA’s responsibility.
