These things invade my apartment every spring/summer. They are the black ones, kinda big, but not huge. They don’t seem to like sweets or crumbs like the brown ants, so the poison traps don’t work. When I call the landlord, they tell me they have to put down poison for the entire building (not just my apartment) and supposedly they schedule them , but I never see any difference. There are like 12 of these black ants crawling on me and my stuff at any given minute. I can’t even bring a girl over :(
