ght below mine), unsure how infested upstairs is. Struggling with LL to get it taken care of, but seems like he's starting to jump on it since we've been nagging him. Found out from upstairs neighbor as well as previous tenants in my apartment that they had an infestation 3 years ago ( originating in same top floor apartment) and about 6 months prior to that as well which was so bad that mattresses and furniture had to be tossed. we're all clean tenants and are unsure how they are getting in, but they are.... it's been a rough ride... hopefully they're gone soon!
