I love you Grim, sorry you are tortured. Aquanet does work, but roaches can be hard to get. In one place I lived, they wouldn't appear until I sat on the Can, I SWEAR THEY KNEW THIS, then they would materialize on the wall in front of me. If I fucking moved one iota, they disappeared. You had be Clint Eastwood to nail one. The ones that fly, according to my life experiences are only in the South.
Good Luck, sometimes Very Loud Yelling and Hammering on the walls and the floors can Help. But you have to watch out for the neighbors and the cops. And even then the results only last for a few minutes.
They are smarter than us. Keep all food and toiletries covered and sealed. Make them go next door to party, and you get the FUCK out of THERE as fast as you can!!!
