being from the SOUTH..I hate cockroaches...to me they mean FILTH...I can not stand the thought of them and have seen them thriving in elecrtical appliances, and cardboard the most! They LOVE cardboard and fabric...
Right now you need to BOMB your room...leaving ALL drawers and closet doors wide open...
THEN you can buy this stuff called Roach Proof...it is a powder that comes in a plastic bottle and you snip the end off and it sort of POOFS out..put that around all the baseboards of the room and anywhere else you think they might run to!
THis stuff is also great for silver fish and spiders....LOVE IT...even had it shipped to Italy to use there...
I wish you luck...and yes everyone should always wash their fabric when they get it...if not for bugs, then the 37 carcinogens that are on it!
