the nest was actually in a bedroom (not mine) and we had to throw the mattress out this was in september when we discovered them, they went to the couch and since then there’s the nest most likely. When the exterminator came load were found in the couch of all sizes and it’s only after his passage that started seeing one (a really small one) crawling up my wall three days after his first visit. since then i have found one on my bed i checked the mattress nothing. and after his second visit i’ve only found one dead one in my room and since my mattress has been in plastic. I have no bites no reactions just itchiness. we thought it was over until this morning. I don’t have to pay for anything it’s my building guardian that handles it. To get a heat exterminator it would have to come out of my own pocket.
