About thirty years ago one of my first "bargain" apartments in the city had roaches really bad - we used a powder called "Roach Death" that was immediatly effective, but once their infested, they're hard to get rid of. They are evil. once one perched on the shower stall and was watching me with its beady little eyes......ewwwww! After my husband woke up one morning with one in the hair on his chest, WE MOVED!
