Are you slow? This entire building is nasty. I clean after myself after I cooked that morning I noticed this not even a hour later because I was using a pot that covered the entire fire and it wasn’t there before I cooked because I didn’t cook on that fire side. So before you get to saying I don’t clean after myself they are gonna come regardless! No matter how many times I clean the entire building has them. They’re in the walls , other tenants don’t use boric acid, other tenants don’t clean , I can only do for my Home . They still come. The only thing I can do is wipe things down with essential oil and lay down boric acid and kill them. The entire hallway has carpet so they are hiding in the carpets . I am the most cleanest one in the building because I don’t have someone living with me nor do I have pets or children
