You're full of crap I lived near there also on Wash st, never had problems with cockroaches, it's one of the nicest areas in the city..your problem I would guess was with cocksuckers.I actually used to live 2 blocks from there back in the 90s. I know it looks nice, but the amount of cockroaches(the little german ones) in that area is freaking insane. My place was sprayed once per week and I still saw roaches everyday and I kept the place spotless.
Anyway, the people who live in that place now are weird. A bunch of paintings of white kids, but a black virgin Mary picture with a black baby Jesus? I wouldn't trust what kind of weird stuff they did in that place.
