Hello - We've dealt with a similar issue at my institution with webbing clothes moths in office areas - I'm just mentioning in case it helps anyone else.
We found the source of the infestation was actually under the cubicle walls - with people eating at their desks, food that fell onto the floor was pushed under these walls during vacuuming as there is a few mm gap. We had a pest company come and spray the infected areas (using deltamethrin if I remember) until we were able to clean the problem areas. It seemed to work, but we were probably also just lucky it hadn't already spread anywhere else.
